Let's divide 53068115 by 21
We're looking to find how many times 21 goes into 53068115.

Moving on to step 1:
5 divided by 21 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 21

Moving on to step 2:
53 divided by 21 is 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 42 from 53, we get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 21

On to step 3:
21 goes into 110 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 105 from 110 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 21

Going ahead to step 4:
When dividing 56 by 21, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 252.0
If we subtract 42 from 56, we get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 21

Step 5:
The number 21 fits into 148 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 2527.0
If we subtract 147 from 148, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 21

Step 6:
11 divided by 21 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 25270.0
If we subtract 0 from 11, we get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 21

Step 7:
If we divide 111 by 21, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 252705.0
If we take 105 away from 111, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 21

Step 8:
The number 21 fits into 65 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 2527053.0
The remainder is 2 after subtracting 63 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 2527053.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
21 goes into 200 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2527053.09
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
21 goes into 110 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2527053.095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
21 goes into 50 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2527053.0952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2527053.09523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 2527053.095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 15:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2527053.095238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 16:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2527053.09523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 2527053.09523809, and the remainder is 1.1e-08.
