We look at the division of 12792254 by 155 
Let's see how many times 155 fits into 12792254.

Step 1:
155 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 155

Advancing to step 2:
When dividing 12 by 155, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 155

On to step 3:
If we divide 127 by 155, we get 0 and a remainder of 127.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Grab the next digit (9) from the dividend, add it to 127, then carry on: 1279 / 155

On to step 4:
The number 155 fits into 1279 8 times, leaving a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 1240 from 1279 to get 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 155

Let's proceed to step 5:
392 divided by 155 is 2 with a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 310 from 392, we get 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 155

Moving on to step 6:
The number 155 fits into 822 5 times, leaving a remainder of 47.
The next digit of our result is 5. 
Result so far: 825.0
Deduct 775 from 822 and we're left with 47.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 155

Moving on to step 7:
475 divided by 155 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 8253.0
The remainder is 10 after subtracting 465 from 475.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 155

Going ahead to step 8:
The number 155 fits into 104 0 times, leaving a remainder of 104.
Write down 0 as next digit of the result. 
Result so far: 82530.0
Deduct 0 from 104 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 9:
155 can be fit into 1040 6 times, resulting in a remainder of 110.
Put 6 as the next digit of the answer. 
Result so far: 82530.6
Subtracting 930 from 1040 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
1100 divided by 155 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 82530.67
The remainder is 15 after subtracting 1085 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
When dividing 150 by 155, we get 0 with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 82530.67
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 12:
The number 155 fits into 1500 9 times, leaving a remainder of 105.
Write down 9 as next digit of the result. 
Result so far: 82530.6709
Subtract 1395 from 1500 to get 105.
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 13:
The number 155 fits into 1050 6 times, leaving a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 82530.67096
Subtracting 930 from 1050 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
If we divide 1200 by 155, we get 7 and a remainder of 115.
Use 7 as the next digit of our solution. 
Result so far: 82530.670967
If we subtract 1085 from 1200, we 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.

Step 15:
The number 155 fits into 1150 7 times, leaving a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 82530.6709677
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 82530.6709677 with a remaining 6.5e-07.
