Let's divide 17070802 by 80
We're looking to find how many times 80 goes into 17070802.

Going ahead to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 80

Advancing to step 2:
17 divided by 80 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 80

On to step 3:
80 goes into 170 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 160 from 170 and we're left with 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 80

Step 4:
80 goes into 107 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 80 from 107 to get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 80

Advancing to step 5:
The number 80 fits into 270 3 times, leaving a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 213.0
If we subtract 240 from 270, we get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 80

On to step 6:
The number 80 fits into 308 3 times, leaving a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 2133.0
Subtract 240 from 308 to get 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 80

Step 7:
80 goes into 680 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 21338.0
If we take 640 away from 680, we end up with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 80

Step 8:
The number 80 fits into 402 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 213385.0
Subtracting 400 from 402 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
80 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 213385.0
Subtracting 0 from 20 leaves us 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 10:
80 goes into 200 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 213385.02
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 213385.025
If we subtract 400 from 400, 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.

Advancing to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 213385.025
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.

Let's proceed to step 13:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 213385.025
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.

Our division results in 213385.025 with a remaining 0.0.
