We look at the division of 86339161 by 155 
We want to divide 86339161 by 155.

Going ahead to step 1:
155 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 155

Going ahead to step 2:
155 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 155

Advancing to step 3:
863 divided by 155 is 5 with a remainder of 88.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 775 away from 863, we end up with 88.
Include the next digit (3) from the dividend after 88, then repeat: 883 / 155

Step 4:
When dividing 883 by 155, we get 5 with a remainder of 108.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtract 775 from 883 to get 108.
Include the next digit (9) from the dividend after 108, then repeat: 1089 / 155

Going ahead to step 5:
The number 155 fits into 1089 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 557.0
If we take 1085 away from 1089, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 155

Going ahead to step 6:
If we divide 41 by 155, we get 0 and a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 5570.0
The remainder is 41 after subtracting 0 from 41.
Include the next digit (6) from the dividend after 41, then repeat: 416 / 155

Going ahead to step 7:
When dividing 416 by 155, we get 2 with a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 55702.0
If we take 310 away from 416, we end up with 106.
Grab the next digit (1) from the dividend, add it to 106, then carry on: 1061 / 155

Going ahead to step 8:
When dividing 1061 by 155, we get 6 with a remainder of 131.
Use 6 as the next digit of our solution. 
Result so far: 557026.0
Subtracting 930 from 1061 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 9:
If we divide 1310 by 155, we get 8 and a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 557026.8
Subtracting 1240 from 1310 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
700 divided by 155 is 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 557026.84
Subtract 620 from 700 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
The number 155 fits into 800 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 557026.845
Subtracting 775 from 800 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
155 can be fit into 250 1 times, resulting in a remainder of 95.
Write down 1 as next digit of the result. 
Result so far: 557026.8451
If we subtract 155 from 250, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 13:
155 goes into 950 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 557026.84516
If we subtract 930 from 950, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
If we divide 200 by 155, we get 1 and a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 557026.845161
Deduct 155 from 200 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 15:
155 can be fit into 450 2 times, resulting in a remainder of 140.
The next digit of our result is 2. 
Result so far: 557026.8451612
If we take 310 away from 450, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
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: 557026.84516129
If we take 1395 away from 1400, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 557026.84516129, and the remainder is 5e-09.
