Let's divide 1983225 by 21
We want to figure out the number of times 1983225 can be divided by 21.

On to step 1:
The number 21 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 21

Let's proceed to step 2:
21 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 21

Let's proceed 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
Subtracting 189 from 198 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 21

Moving on to step 4:
21 can be fit into 93 4 times, resulting in a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Subtracting 84 from 93 leaves us with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 21

Advancing to step 5:
21 goes into 92 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 944.0
If we take 84 away from 92, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 21

Moving on to step 6:
21 can be fit into 82 3 times, resulting in a remainder of 19.
The next digit of our result is 3. 
Result so far: 9443.0
If we take 63 away from 82, we end up with 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 21

Step 7:
If we divide 195 by 21, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 94439.0
Deduct 189 from 195 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead 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: 94439.2
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 94439.28
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 94439.285
If we take 105 away from 120, we end up 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.

Moving on to step 11:
21 goes into 150 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 94439.2857
Subtracting 147 from 150 leaves us with 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 can be fit into 30 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 94439.28571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
When dividing 90 by 21, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 94439.285714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 94439.2857142
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.

On to step 15:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 94439.28571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 94439.28571428, and the remainder is 1.2e-08.
