We look at the division of 80779442 by 155 
We're looking to find how many times 155 goes into 80779442.

On to step 1:
The number 155 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 155

Moving on to step 2:
155 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 155

Going ahead to step 3:
807 divided by 155 is 5 with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 775 from 807 leaves us with 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 155

On to step 4:
The number 155 fits into 327 2 times, leaving a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 310 from 327, we get 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 155

Moving on to step 5:
179 divided by 155 is 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 521.0
If we subtract 155 from 179, we get 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 155

Advancing to step 6:
When dividing 244 by 155, we get 1 with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 5211.0
The remainder is 89 after subtracting 155 from 244.
Bring next digit (4) of the dividend behind the 89 and repeat the process: 894 / 155

Going ahead to step 7:
155 goes into 894 5 times with a remainder of 119.
Write down 5 as next digit of the result. 
Result so far: 52115.0
If we subtract 775 from 894, we get 119.
Bring next digit (2) of the dividend behind the 119 and repeat the process: 1192 / 155

On to step 8:
155 can be fit into 1192 7 times, resulting in a remainder of 107.
The number 7 becomes the next digit in our result. 
Result so far: 521157.0
Subtract 1085 from 1192 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 9:
155 goes into 1070 6 times with a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 521157.6
If we subtract 930 from 1070, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
155 goes into 1400 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 521157.69
If we subtract 1395 from 1400, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
The number 155 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 521157.69
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
The number 155 fits into 500 3 times, leaving a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 521157.6903
If we subtract 465 from 500, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
155 goes into 350 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 521157.69032
Subtract 310 from 350 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
155 goes into 400 2 times with a remainder of 90.
The next digit of our result is 2. 
Result so far: 521157.690322
Subtracting 310 from 400 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 521157.690322 with a remaining 9e-06.
