62086931 ÷ 644 
Our goal is to divide 62086931 by 644.

Moving on to step 1:
644 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 644

Moving on to step 2:
The number 644 fits into 62 0 times, leaving a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 644

Going ahead to step 3:
644 goes into 620 0 times with a remainder of 620.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 620, we end up with 620.
Fetch the next digit (8) from the dividend, attach it to 620 and continue: 6208 / 644

On to step 4:
If we divide 6208 by 644, we get 9 and a remainder of 412.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 5796 from 6208 to get 412.
Grab the next digit (6) from the dividend, add it to 412, then carry on: 4126 / 644

Going ahead to step 5:
When dividing 4126 by 644, we get 6 with a remainder of 262.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 262 after subtracting 3864 from 4126.
Include the next digit (9) from the dividend after 262, then repeat: 2629 / 644

On to step 6:
If we divide 2629 by 644, we get 4 and a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 964.0
If we take 2576 away from 2629, we end up with 53.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 644

Going ahead to step 7:
When dividing 533 by 644, we get 0 with a remainder of 533.
The number 0 becomes the next digit in our result. 
Result so far: 9640.0
Subtracting 0 from 533 leaves us with 533.
Include the next digit (1) from the dividend after 533, then repeat: 5331 / 644

Going ahead to step 8:
5331 divided by 644 is 8 with a remainder of 179.
Write down 8 as next digit of the result. 
Result so far: 96408.0
Subtracting 5152 from 5331 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 9:
If we divide 1790 by 644, we get 2 and a remainder of 502.
Write down 2 as next digit of the result. 
Result so far: 96408.2
The remainder is 502 after subtracting 1288 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

On to step 10:
644 can be fit into 5020 7 times, resulting in a remainder of 512.
Put 7 as the next digit of the answer. 
Result so far: 96408.27
Deduct 4508 from 5020 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 11:
5120 divided by 644 is 7 with a remainder of 612.
The next digit of our result is 7. 
Result so far: 96408.277
If we take 4508 away from 5120, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

The final result is 96408.277 with a remainder of 0.0612.
