Let's divide 77412646 by 637
Our goal is to divide 77412646 by 637.

Going ahead to step 1:
If we divide 7 by 637, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 637

Let's proceed to step 2:
When dividing 77 by 637, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 637

Moving on to step 3:
774 divided by 637 is 1 with a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 137 after subtracting 637 from 774.
Grab the next digit (1) from the dividend, add it to 137, then carry on: 1371 / 637

Moving on to step 4:
The number 637 fits into 1371 2 times, leaving a remainder of 97.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1274 from 1371, we get 97.
Include the next digit (2) from the dividend after 97, then repeat: 972 / 637

Going ahead to step 5:
The number 637 fits into 972 1 times, leaving a remainder of 335.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
The remainder is 335 after subtracting 637 from 972.
Append the next digit (6) from the dividend to 335 and continue with: 3356 / 637

On to step 6:
637 goes into 3356 5 times with a remainder of 171.
Write down 5 as next digit of the result. 
Result so far: 1215.0
Subtracting 3185 from 3356 leaves us with 171.
Fetch the next digit (4) from the dividend, attach it to 171 and continue: 1714 / 637

Step 7:
When dividing 1714 by 637, we get 2 with a remainder of 440.
The number 2 becomes the next digit in our result. 
Result so far: 12152.0
Subtracting 1274 from 1714 leaves us with 440.
Include the next digit (6) from the dividend after 440, then repeat: 4406 / 637

Moving on to step 8:
637 can be fit into 4406 6 times, resulting in a remainder of 584.
The next digit of our result is 6. 
Result so far: 121526.0
If we take 3822 away from 4406, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 9:
5840 divided by 637 is 9 with a remainder of 107.
The next digit of our result is 9. 
Result so far: 121526.9
Deduct 5733 from 5840 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 10:
637 goes into 1070 1 times with a remainder of 433.
The number 1 becomes the next digit in our result. 
Result so far: 121526.91
Deduct 637 from 1070 and we're left 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 11:
If we divide 4330 by 637, we get 6 and a remainder of 508.
The next digit of our result is 6. 
Result so far: 121526.916
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.

Going ahead to step 12:
If we divide 5080 by 637, we get 7 and a remainder of 621.
The number 7 becomes the next digit in our result. 
Result so far: 121526.9167
If we subtract 4459 from 5080, we get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

On to step 13:
6210 divided by 637 is 9 with a remainder of 477.
Use 9 as the next digit of our solution. 
Result so far: 121526.91679
Subtracting 5733 from 6210 leaves us with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

On to step 14:
637 goes into 4770 7 times with a remainder of 311.
Put 7 as the next digit of the answer. 
Result so far: 121526.916797
The remainder is 311 after subtracting 4459 from 4770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 15:
3110 divided by 637 is 4 with a remainder of 562.
Record the quotient 4 as the next digit in the result. 
Result so far: 121526.9167974
The remainder is 562 after subtracting 2548 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 16:
5620 divided by 637 is 8 with a remainder of 524.
The next digit of our result is 8. 
Result so far: 121526.91679748
If we take 5096 away from 5620, we end up 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.

The final outcome is 121526.91679748, with a leftover of 5.24e-07.
