We're dividing 712170 by 80 
Let's see how many times 80 fits into 712170.

Going ahead to step 1:
80 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 80

Moving on to step 2:
71 divided by 80 is 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 80

Advancing to step 3:
80 can be fit into 712 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 640 from 712 leaves us with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 80

On to step 4:
80 goes into 721 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Deduct 720 from 721 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 80

Let's proceed to step 5:
80 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 890.0
If we subtract 0 from 17, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 80

Let's proceed to step 6:
80 can be fit into 170 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 8902.0
Subtract 160 from 170 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.

Advancing to step 7:
80 goes into 100 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 8902.1
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 80 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 8902.12
Subtracting 160 from 200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 8902.125
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8902.125
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.

Going ahead to step 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8902.125
Subtracting 0 from 0 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.

The quotient of the division is 8902.125, and the remainder is 0.0.
