12490637 ÷ 628 
We want to divide 12490637 by 628.

Moving on to step 1:
1 divided by 628 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 628

Step 2:
When dividing 12 by 628, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 628

Going ahead to step 3:
When dividing 124 by 628, we get 0 with a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Bring next digit (9) of the dividend behind the 124 and repeat the process: 1249 / 628

On to step 4:
628 can be fit into 1249 1 times, resulting in a remainder of 621.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 628 away from 1249, we end up with 621.
Grab the next digit (0) from the dividend, add it to 621, then carry on: 6210 / 628

Going ahead to step 5:
When dividing 6210 by 628, we get 9 with a remainder of 558.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 5652 away from 6210, we end up with 558.
Grab the next digit (6) from the dividend, add it to 558, then carry on: 5586 / 628

On to step 6:
When dividing 5586 by 628, we get 8 with a remainder of 562.
Put 8 as the next digit of the answer. 
Result so far: 198.0
Deduct 5024 from 5586 and we're left with 562.
Take the next digit (3) from the dividend and append it to 562, then repeat: 5623 / 628

Moving on to step 7:
628 goes into 5623 8 times with a remainder of 599.
Use 8 as the next digit of our solution. 
Result so far: 1988.0
If we take 5024 away from 5623, we end up with 599.
Append the next digit (7) from the dividend to 599 and continue with: 5997 / 628

Moving on to step 8:
The number 628 fits into 5997 9 times, leaving a remainder of 345.
Record the quotient 9 as the next digit in the result. 
Result so far: 19889.0
If we take 5652 away from 5997, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Going ahead to step 9:
When dividing 3450 by 628, we get 5 with a remainder of 310.
The next digit of our result is 5. 
Result so far: 19889.5
If we subtract 3140 from 3450, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
628 goes into 3100 4 times with a remainder of 588.
The next digit of our result is 4. 
Result so far: 19889.54
The remainder is 588 after subtracting 2512 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 11:
When dividing 5880 by 628, we get 9 with a remainder of 228.
Use 9 as the next digit of our solution. 
Result so far: 19889.549
The remainder is 228 after subtracting 5652 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 12:
The number 628 fits into 2280 3 times, leaving a remainder of 396.
Write down 3 as next digit of the result. 
Result so far: 19889.5493
The remainder is 396 after subtracting 1884 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 13:
The number 628 fits into 3960 6 times, leaving a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 19889.54936
If we take 3768 away from 3960, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 14:
If we divide 1920 by 628, we get 3 and a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 19889.549363
Subtracting 1884 from 1920 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 15:
The number 628 fits into 360 0 times, leaving a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 19889.549363
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 16:
If we divide 3600 by 628, we get 5 and a remainder of 460.
Record the quotient 5 as the next digit in the result. 
Result so far: 19889.54936305
Subtracting 3140 from 3600 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 19889.54936305, with a leftover of 4.6e-07.
