We divide 53697 by 21
We want to divide 53697 by 21.

Step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 21

Going ahead to step 2:
53 divided by 21 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 42 from 53 to get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 21

Let's proceed to step 3:
The number 21 fits into 116 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 105 away from 116, we end up with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 21

On to step 4:
When dividing 119 by 21, we get 5 with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 255.0
Subtract 105 from 119 to get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 21

Advancing to step 5:
When dividing 147 by 21, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 2557.0
If we subtract 147 from 147, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 6:
If we divide 0 by 21, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2557.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
21 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2557.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 2557.0, with a leftover of 0.0.
