We're dividing 966182 by 21 
We're looking to find how many times 21 goes into 966182.

Advancing to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 21

Moving on to step 2:
If we divide 96 by 21, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 84 away from 96, we end up with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 21

Moving on to step 3:
If we divide 126 by 21, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 0 after subtracting 126 from 126.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 21

Going ahead to step 4:
The number 21 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 460.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 21

Going ahead to step 5:
18 divided by 21 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 4600.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 21

Moving on to step 6:
21 goes into 182 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 46008.0
Subtract 168 from 182 to get 14.
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 7:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 46008.6
If we take 126 away from 140, we end up with 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 8:
When dividing 140 by 21, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 46008.66
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 46008.66, with a leftover of 0.014.
