We divide 955402 by 21
Our goal is to divide 955402 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
The remainder is 9 after subtracting 0 from 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 21

Going ahead to step 2:
If we divide 95 by 21, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 84 from 95 leaves us with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 21

Advancing to step 3:
If we divide 115 by 21, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 105 from 115 to get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 21

Advancing to step 4:
21 can be fit into 104 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 454.0
Subtract 84 from 104 to get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 21

Step 5:
If we divide 200 by 21, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 4549.0
Deduct 189 from 200 and we're left with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 21

Let's proceed to step 6:
21 goes into 112 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 45495.0
Subtract 105 from 112 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 21 fits into 70 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 45495.3
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
If we divide 70 by 21, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 45495.33
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 45495.33 with a balance of 0.007.
