Let's divide 99175650 by 21
Our goal is to divide 99175650 by 21.

On to step 1:
When dividing 9 by 21, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 21

On to step 2:
99 divided by 21 is 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 84 away from 99, we end up with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 21

Step 3:
If we divide 151 by 21, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 147 from 151 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 21

Moving on to step 4:
When dividing 47 by 21, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 472.0
If we subtract 42 from 47, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 21

On to step 5:
The number 21 fits into 55 2 times, leaving a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 4722.0
Subtract 42 from 55 to get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 21

Moving on to step 6:
When dividing 136 by 21, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 47226.0
Deduct 126 from 136 and we're left with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 21

Going ahead to step 7:
105 divided by 21 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 472265.0
If we take 105 away from 105, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 21

Going ahead to step 8:
21 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4722650.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
21 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4722650.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 21 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4722650.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4722650.0, with a leftover of 0.0.
