Let's divide 198522 by 21
We want to divide 198522 by 21.

On to step 1:
1 divided by 21 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 21

Moving on to step 2:
If we divide 19 by 21, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 21

Advancing to step 3:
If we divide 198 by 21, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 189 from 198 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 21

Step 4:
21 can be fit into 95 4 times, resulting in a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 94.0
The remainder is 11 after subtracting 84 from 95.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 21

Moving on to step 5:
If we divide 112 by 21, we get 5 and a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 945.0
If we subtract 105 from 112, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 21

On to step 6:
21 goes into 72 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 9453.0
The remainder is 9 after subtracting 63 from 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 9453.4
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 9453.42
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
When dividing 180 by 21, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 9453.428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
If we divide 120 by 21, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 9453.4285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
150 divided by 21 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 9453.42857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
21 goes into 30 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 9453.428571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
If we divide 90 by 21, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 9453.4285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 9453.42857142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 9453.42857142 with a balance of 1.8e-08.
