4,024 divided by 68 using Partial qoutients

LiRa [457]

We will use Partial quotients to find the quotient and remainder of 4024 divided by 68.

Step 1: $68 \times 50 = 3400$

Now, we will subtract 3400 from 4024,

we get remainder as 624.

Step 2: $68 \times 5 = 340$

Subtracting 340 from 624,

we get remainder as 284.

Step 3: $68 \times 4 = 272$

Subtracting 272 from 284,

we get remainder as 12.

So, Quotient = $50 + 5+ 4 = 59$ and Remainder is 12.
