We look at the division of 718362 by 21 
We're looking to find how many times 21 goes into 718362.

Advancing to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
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:
21 goes into 71 3 times 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.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 21

Moving on to step 3:
21 goes into 88 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 84 from 88 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 21

Step 4:
21 can be fit into 43 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 342.0
If we take 42 away from 43, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 21

On to step 5:
21 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 3420.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 21

Step 6:
21 goes into 162 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 34207.0
If we subtract 147 from 162, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 21, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 34207.7
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
21 goes into 30 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 34207.71
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 34207.714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
60 divided by 21 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 34207.7142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
180 divided by 21 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 34207.71428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 34207.714285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
When dividing 150 by 21, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 34207.7142857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
30 divided by 21 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 34207.71428571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 34207.71428571 and a remainder of 9e-09.
