We're dividing 918215 by 10 
We want to figure out the number of times 918215 can be divided by 10.

Moving on to step 1:
10 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 10

On to step 2:
When dividing 91 by 10, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 1 after subtracting 90 from 91.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 10

Advancing to step 3:
10 can be fit into 18 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtract 10 from 18 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 10

On to step 4:
82 divided by 10 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 918.0
The remainder is 2 after subtracting 80 from 82.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 10

Advancing to step 5:
When dividing 21 by 10, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 9182.0
If we subtract 20 from 21, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 10

Going ahead to step 6:
When dividing 15 by 10, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 91821.0
Subtracting 10 from 15 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.

Going ahead to step 7:
10 can be fit into 50 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 91821.5
Subtract 50 from 50 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 10 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 91821.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 91821.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 91821.5, and the remainder is 0.0.
