We're dividing 80715270 by 155 
We want to figure out the number of times 80715270 can be divided by 155.

Let's proceed to step 1:
The number 155 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 155

On to step 2:
The number 155 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 155

Step 3:
155 goes into 807 5 times with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 775 from 807 to get 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 155

Advancing to step 4:
155 goes into 321 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 52.0
The remainder is 11 after subtracting 310 from 321.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 155

On to step 5:
If we divide 115 by 155, we get 0 and a remainder of 115.
Write down 0 as next digit of the result. 
Result so far: 520.0
Deduct 0 from 115 and we're left with 115.
Append the next digit (2) from the dividend to 115 and continue with: 1152 / 155

Going ahead to step 6:
If we divide 1152 by 155, we get 7 and a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 5207.0
Subtract 1085 from 1152 to get 67.
Fetch the next digit (7) from the dividend, attach it to 67 and continue: 677 / 155

Advancing to step 7:
The number 155 fits into 677 4 times, leaving a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 52074.0
If we subtract 620 from 677, we get 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 155

Advancing to step 8:
When dividing 570 by 155, we get 3 with a remainder of 105.
The next digit of our result is 3. 
Result so far: 520743.0
The remainder is 105 after subtracting 465 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 9:
The number 155 fits into 1050 6 times, leaving a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 520743.6
The remainder is 120 after subtracting 930 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
When dividing 1200 by 155, we get 7 with a remainder of 115.
The next digit of our result is 7. 
Result so far: 520743.67
Subtract 1085 from 1200 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 11:
155 can be fit into 1150 7 times, resulting in a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 520743.677
Deduct 1085 from 1150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 520743.677 with a remaining 0.0065.
