715726 ÷ 21 
We want to divide 715726 by 21.

Going ahead to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 21

On to step 2:
When dividing 71 by 21, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 8 after subtracting 63 from 71.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 21

Going ahead to step 3:
If we divide 85 by 21, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 84 from 85 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 21

Let's proceed to step 4:
17 divided by 21 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 340.0
Subtract 0 from 17 to get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 21

Advancing to step 5:
When dividing 172 by 21, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 3408.0
If we take 168 away from 172, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 21

Step 6:
The number 21 fits into 46 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 34082.0
Subtracting 42 from 46 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 34082.1
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 34082.19
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 34082.19
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 21, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 34082.1904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 21, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 34082.19047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 34082.190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 34082.1904761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 34082.19047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 34082.19047619 with a balance of 1e-09.
