We divide 902075 by 21
Our goal is to divide 902075 by 21.

Advancing to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 21

Step 2:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 84 from 90 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 21

Going ahead to step 3:
The number 21 fits into 62 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 20 after subtracting 42 from 62.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 21

Advancing to step 4:
21 goes into 200 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 429.0
Subtract 189 from 200 to get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 21

Advancing to step 5:
21 can be fit into 117 5 times, resulting in a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 4295.0
Deduct 105 from 117 and we're left with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 21

Step 6:
21 goes into 125 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 42955.0
Deduct 105 from 125 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
When dividing 200 by 21, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 42955.9
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
If we divide 110 by 21, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 42955.95
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 42955.952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
If we divide 80 by 21, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 42955.9523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
If we divide 170 by 21, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 42955.95238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
20 divided by 21 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 42955.95238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
If we divide 200 by 21, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 42955.9523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
21 goes into 110 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 42955.95238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 42955.95238095 with a remainder of 5e-09.
