We look at the division of 8317991 by 10 
We want to figure out the number of times 8317991 can be divided by 10.

Going ahead to step 1:
The number 10 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 10

Moving on to step 2:
If we divide 83 by 10, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 80 from 83 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 10

On to step 3:
If we divide 31 by 10, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 1 after subtracting 30 from 31.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 10

Advancing to step 4:
10 can be fit into 17 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 831.0
Subtract 10 from 17 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 10

Moving on to step 5:
If we divide 79 by 10, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 8317.0
If we take 70 away from 79, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 10

Moving on to step 6:
10 can be fit into 99 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 83179.0
The remainder is 9 after subtracting 90 from 99.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 10

Going ahead to step 7:
91 divided by 10 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 831799.0
Subtract 90 from 91 to 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.

On to step 8:
10 divided by 10 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 831799.1
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 831799.1
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 831799.1
If we take 0 away from 0, we end up with 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 final result is 831799.1 with a remainder of 0.0.
