Let's divide 715495 by 21
Our goal is to divide 715495 by 21.

Going ahead to step 1:
21 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 21

Let's proceed to step 2:
When dividing 71 by 21, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 63 from 71 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 21

Moving on to step 3:
The number 21 fits into 85 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 84 from 85, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

Step 4:
14 divided by 21 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 340.0
Subtract 0 from 14 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 21

Moving on to step 5:
The number 21 fits into 149 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 3407.0
If we subtract 147 from 149, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 21

Going ahead to step 6:
25 divided by 21 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 34071.0
Subtracting 21 from 25 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.

Moving on to step 7:
21 goes into 40 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 34071.1
Subtract 21 from 40 to 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.

On to step 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 34071.19
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 34071.19
Subtract 0 from 10 to 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.

Going ahead to step 10:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 34071.1904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 21, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 34071.19047
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.

Moving on to step 12:
If we divide 130 by 21, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 34071.190476
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.

Advancing to step 13:
40 divided by 21 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 34071.1904761
Subtracting 21 from 40 leaves us 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.

Let's proceed to step 14:
190 divided by 21 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 34071.19047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 34071.19047619 with a remainder of 1e-09.
