We look at the division of 20900661 by 624 
We want to divide 20900661 by 624.

Advancing to step 1:
When dividing 2 by 624, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 624

On to step 2:
When dividing 20 by 624, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 624

On to step 3:
209 divided by 624 is 0 with a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Append the next digit (0) from the dividend to 209 and continue with: 2090 / 624

On to step 4:
624 goes into 2090 3 times with a remainder of 218.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 218 after subtracting 1872 from 2090.
Grab the next digit (0) from the dividend, add it to 218, then carry on: 2180 / 624

Moving on to step 5:
When dividing 2180 by 624, we get 3 with a remainder of 308.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 1872 from 2180 leaves us with 308.
Take the next digit (6) from the dividend and append it to 308, then repeat: 3086 / 624

Going ahead to step 6:
When dividing 3086 by 624, we get 4 with a remainder of 590.
The next digit of our result is 4. 
Result so far: 334.0
If we take 2496 away from 3086, we end up with 590.
Include the next digit (6) from the dividend after 590, then repeat: 5906 / 624

On to step 7:
624 goes into 5906 9 times with a remainder of 290.
The next digit of our result is 9. 
Result so far: 3349.0
If we subtract 5616 from 5906, we get 290.
Include the next digit (1) from the dividend after 290, then repeat: 2901 / 624

Let's proceed to step 8:
624 goes into 2901 4 times with a remainder of 405.
Use 4 as the next digit of our solution. 
Result so far: 33494.0
If we subtract 2496 from 2901, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 9:
The number 624 fits into 4050 6 times, leaving a remainder of 306.
Write down 6 as next digit of the result. 
Result so far: 33494.6
Subtracting 3744 from 4050 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 10:
624 can be fit into 3060 4 times, resulting in a remainder of 564.
Put 4 as the next digit of the answer. 
Result so far: 33494.64
Deduct 2496 from 3060 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 11:
624 can be fit into 5640 9 times, resulting in a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 33494.649
If we subtract 5616 from 5640, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
240 divided by 624 is 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 33494.649
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
624 can be fit into 2400 3 times, resulting in a remainder of 528.
Use 3 as the next digit of our solution. 
Result so far: 33494.64903
If we subtract 1872 from 2400, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 14:
624 can be fit into 5280 8 times, resulting in a remainder of 288.
Put 8 as the next digit of the answer. 
Result so far: 33494.649038
Subtracting 4992 from 5280 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 15:
The number 624 fits into 2880 4 times, leaving a remainder of 384.
The next digit of our result is 4. 
Result so far: 33494.6490384
Deduct 2496 from 2880 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 16:
The number 624 fits into 3840 6 times, leaving a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 33494.64903846
The remainder is 96 after subtracting 3744 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 33494.64903846 and a remainder of 9.6e-08.
