Let's divide 955724 by 21
Let's see how many times 21 fits into 955724.

Going ahead to step 1:
21 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 21

Let's proceed to step 2:
The number 21 fits into 95 4 times, leaving 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

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
If we subtract 105 from 115, we get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 21

Moving on to step 4:
If we divide 107 by 21, we get 5 and a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 455.0
Deduct 105 from 107 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 21

Let's proceed to step 5:
The number 21 fits into 22 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 4551.0
Deduct 21 from 22 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 21

Going ahead to step 6:
When dividing 14 by 21, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 45510.0
The remainder is 14 after subtracting 0 from 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
21 goes into 140 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 45510.6
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 45510.66
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 45510.66, with a leftover of 0.014.
