Let's divide 724376 by 21
We want to divide 724376 by 21.

Going ahead to step 1:
7 divided by 21 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 21

Advancing to step 2:
21 can be fit into 72 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 63 from 72, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 21

Step 3:
21 goes into 94 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 84 from 94 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 21

Let's proceed to step 4:
If we divide 103 by 21, we get 4 and a remainder of 19.
The next digit of our result is 4. 
Result so far: 344.0
If we subtract 84 from 103, we get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 21

Step 5:
21 goes into 197 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 3449.0
If we subtract 189 from 197, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 21

Advancing to step 6:
21 goes into 86 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 34494.0
Subtract 84 from 86 to 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 7:
When dividing 20 by 21, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 34494.0
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 8:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 34494.09
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.

Going ahead to step 9:
21 goes into 110 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 34494.095
Deduct 105 from 110 and we're left 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.

Going ahead to step 10:
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: 34494.0952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 34494.09523
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.

Going ahead to step 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 34494.095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
If we divide 20 by 21, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 34494.095238
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.

On to step 14:
If we divide 200 by 21, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 34494.09523809
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 final result is 34494.09523809 with a remainder of 1.1e-08.
