927353 ÷ 21 
We're looking to find how many times 21 goes into 927353.

Going ahead 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
If we subtract 0 from 9, we get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 21

Moving on to step 2:
If we divide 92 by 21, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 84 away from 92, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 21

Moving on to step 3:
When dividing 87 by 21, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 84 from 87 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 21

Step 4:
21 can be fit into 33 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 441.0
Subtract 21 from 33 to get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 21

Moving on to step 5:
The number 21 fits into 125 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 4415.0
Deduct 105 from 125 and we're left with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 21

On to step 6:
The number 21 fits into 203 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 44159.0
Deduct 189 from 203 and we're left 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 7:
If we divide 140 by 21, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 44159.6
Subtract 126 from 140 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.

Step 8:
21 goes into 140 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 44159.66
Subtracting 126 from 140 leaves us 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.

After the division, we end up with 44159.66 and a remainder of 0.014.
