Let's divide 20004199 by 921
We want to divide 20004199 by 921.

On to step 1:
The number 921 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 921

On to step 2:
20 divided by 921 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 921

Advancing to step 3:
The number 921 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 200 after subtracting 0 from 200.
Append the next digit (0) from the dividend to 200 and continue with: 2000 / 921

Going ahead to step 4:
921 goes into 2000 2 times with a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1842 from 2000 leaves us with 158.
Fetch the next digit (4) from the dividend, attach it to 158 and continue: 1584 / 921

On to step 5:
If we divide 1584 by 921, we get 1 and a remainder of 663.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 663 after subtracting 921 from 1584.
Grab the next digit (1) from the dividend, add it to 663, then carry on: 6631 / 921

On to step 6:
The number 921 fits into 6631 7 times, leaving a remainder of 184.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
Deduct 6447 from 6631 and we're left with 184.
Bring next digit (9) of the dividend behind the 184 and repeat the process: 1849 / 921

On to step 7:
921 goes into 1849 2 times with a remainder of 7.
The next digit of our result is 2. 
Result so far: 2172.0
Subtract 1842 from 1849 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 921

On to step 8:
921 goes into 79 0 times with a remainder of 79.
The next digit of our result is 0. 
Result so far: 21720.0
Subtract 0 from 79 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 9:
921 can be fit into 790 0 times, resulting in a remainder of 790.
The next digit of our result is 0. 
Result so far: 21720.0
The remainder is 790 after subtracting 0 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 10:
The number 921 fits into 7900 8 times, leaving a remainder of 532.
The next digit of our result is 8. 
Result so far: 21720.08
Subtracting 7368 from 7900 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 11:
921 goes into 5320 5 times with a remainder of 715.
The number 5 becomes the next digit in our result. 
Result so far: 21720.085
If we take 4605 away from 5320, we end up with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Moving on to step 12:
When dividing 7150 by 921, we get 7 with a remainder of 703.
Record the quotient 7 as the next digit in the result. 
Result so far: 21720.0857
Deduct 6447 from 7150 and we're left with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Going ahead to step 13:
The number 921 fits into 7030 7 times, leaving a remainder of 583.
The number 7 becomes the next digit in our result. 
Result so far: 21720.08577
The remainder is 583 after subtracting 6447 from 7030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

In conclusion, the division gives 21720.08577 with a balance of 0.000583.
