57722 divided by 21 
We're looking to find how many times 21 goes into 57722.

Moving on to step 1:
When dividing 5 by 21, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 21

On to step 2:
21 goes into 57 2 times with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 42 from 57 leaves us with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 21

On to step 3:
157 divided by 21 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 147 from 157 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 21

Moving on to step 4:
21 can be fit into 102 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 274.0
If we subtract 84 from 102, we get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 21

Going ahead to step 5:
21 goes into 182 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 2748.0
Deduct 168 from 182 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.

Step 6:
When dividing 140 by 21, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 2748.6
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.

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: 2748.66
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 result is 2748.66 with a remainder of 0.014.
