Let's divide 991970 by 10
We want to divide 991970 by 10.

Going ahead to step 1:
10 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 10

Going ahead to step 2:
If we divide 99 by 10, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 90 from 99 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 10

Going ahead to step 3:
If we divide 91 by 10, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 99.0
Subtract 90 from 91 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 10

Advancing to step 4:
The number 10 fits into 19 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 991.0
Deduct 10 from 19 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 10

Step 5:
10 can be fit into 97 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 9919.0
If we take 90 away from 97, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 10

On to step 6:
When dividing 70 by 10, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 99197.0
Subtracting 70 from 70 leaves us 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 7:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 99197.0
The remainder is 0 after subtracting 0 from 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 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 99197.0
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.

After the division, we end up with 99197.0 and a remainder of 0.0.
