We're dividing 19996604 by 629 
We want to divide 19996604 by 629.

Step 1:
629 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 629

Step 2:
The number 629 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 629

Step 3:
629 can be fit into 199 0 times, resulting in a remainder of 199.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 199 leaves us with 199.
Grab the next digit (9) from the dividend, add it to 199, then carry on: 1999 / 629

Let's proceed to step 4:
629 can be fit into 1999 3 times, resulting in a remainder of 112.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1887 from 1999 to get 112.
Fetch the next digit (6) from the dividend, attach it to 112 and continue: 1126 / 629

Going ahead to step 5:
1126 divided by 629 is 1 with a remainder of 497.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 629 from 1126 to get 497.
Append the next digit (6) from the dividend to 497 and continue with: 4976 / 629

Let's proceed to step 6:
4976 divided by 629 is 7 with a remainder of 573.
Use 7 as the next digit of our solution. 
Result so far: 317.0
Deduct 4403 from 4976 and we're left with 573.
Bring next digit (0) of the dividend behind the 573 and repeat the process: 5730 / 629

Moving on to step 7:
The number 629 fits into 5730 9 times, leaving a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 3179.0
Deduct 5661 from 5730 and we're left with 69.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 629

Advancing to step 8:
629 can be fit into 694 1 times, resulting in a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 31791.0
Subtracting 629 from 694 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
629 goes into 650 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 31791.1
Subtracting 629 from 650 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
210 divided by 629 is 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 31791.1
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 11:
The number 629 fits into 2100 3 times, leaving a remainder of 213.
Put 3 as the next digit of the answer. 
Result so far: 31791.103
Subtracting 1887 from 2100 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 12:
629 goes into 2130 3 times with a remainder of 243.
Write down 3 as next digit of the result. 
Result so far: 31791.1033
If we take 1887 away from 2130, we end up with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

After the division, we end up with 31791.1033 and a remainder of 0.00243.
