We look at the division of 727337 by 21 
We want to divide 727337 by 21.

Going ahead to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 21

Let's proceed to step 2:
72 divided by 21 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 63 from 72 to get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 21

Advancing to step 3:
21 can be fit into 97 4 times, resulting in a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 84 from 97, we get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 21

Let's proceed to step 4:
21 can be fit into 133 6 times, resulting in a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 346.0
Subtract 126 from 133 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 21

Going ahead to step 5:
21 can be fit into 73 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3463.0
Deduct 63 from 73 and we're left with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 21

Going ahead to step 6:
21 goes into 107 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 34635.0
If we take 105 away from 107, we end up with 2.
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 7:
When dividing 20 by 21, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 34635.0
If we take 0 away from 20, we end up 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.

Let's proceed to step 8:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 34635.09
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.

Advancing to step 9:
When dividing 110 by 21, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 34635.095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 34635.0952
If we subtract 42 from 50, we 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.

Going ahead to step 11:
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: 34635.09523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
The number 21 fits into 170 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 34635.095238
Deduct 168 from 170 and we're left with 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 13:
When dividing 20 by 21, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 34635.095238
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.

Let's proceed to step 14:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 34635.09523809
Subtract 189 from 200 to get 11.
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 34635.09523809, and the remainder is 1.1e-08.
