39979501 ÷ 637 
Our goal is to divide 39979501 by 637.

On to step 1:
If we divide 3 by 637, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 637

On to step 2:
39 divided by 637 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 637

Let's proceed to step 3:
If we divide 399 by 637, we get 0 and a remainder of 399.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 399, we get 399.
Fetch the next digit (7) from the dividend, attach it to 399 and continue: 3997 / 637

Going ahead to step 4:
If we divide 3997 by 637, we get 6 and a remainder of 175.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 175 after subtracting 3822 from 3997.
Include the next digit (9) from the dividend after 175, then repeat: 1759 / 637

Advancing to step 5:
1759 divided by 637 is 2 with a remainder of 485.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Subtract 1274 from 1759 to get 485.
Append the next digit (5) from the dividend to 485 and continue with: 4855 / 637

Advancing to step 6:
637 can be fit into 4855 7 times, resulting in a remainder of 396.
Write down 7 as next digit of the result. 
Result so far: 627.0
Subtract 4459 from 4855 to get 396.
Append the next digit (0) from the dividend to 396 and continue with: 3960 / 637

Moving on to step 7:
3960 divided by 637 is 6 with a remainder of 138.
The next digit of our result is 6. 
Result so far: 6276.0
If we subtract 3822 from 3960, we get 138.
Include the next digit (1) from the dividend after 138, then repeat: 1381 / 637

Going ahead to step 8:
If we divide 1381 by 637, we get 2 and a remainder of 107.
Use 2 as the next digit of our solution. 
Result so far: 62762.0
The remainder is 107 after subtracting 1274 from 1381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 9:
637 can be fit into 1070 1 times, resulting in a remainder of 433.
Write down 1 as next digit of the result. 
Result so far: 62762.1
Subtracting 637 from 1070 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Going ahead to step 10:
If we divide 4330 by 637, we get 6 and a remainder of 508.
Write down 6 as next digit of the result. 
Result so far: 62762.16
If we subtract 3822 from 4330, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 11:
637 goes into 5080 7 times with a remainder of 621.
Write down 7 as next digit of the result. 
Result so far: 62762.167
Deduct 4459 from 5080 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Let's proceed to step 12:
637 goes into 6210 9 times with a remainder of 477.
Write down 9 as next digit of the result. 
Result so far: 62762.1679
The remainder is 477 after subtracting 5733 from 6210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Going ahead to step 13:
The number 637 fits into 4770 7 times, leaving a remainder of 311.
The next digit of our result is 7. 
Result so far: 62762.16797
Subtract 4459 from 4770 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 14:
If we divide 3110 by 637, we get 4 and a remainder of 562.
The next digit of our result is 4. 
Result so far: 62762.167974
Subtract 2548 from 3110 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Advancing to step 15:
637 can be fit into 5620 8 times, resulting in a remainder of 524.
The number 8 becomes the next digit in our result. 
Result so far: 62762.1679748
Deduct 5096 from 5620 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 16:
The number 637 fits into 5240 8 times, leaving a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 62762.16797488
Subtracting 5096 from 5240 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 62762.16797488, with a leftover of 1.44e-07.
