Let's divide 86566213 by 155
Let's see how many times 155 fits into 86566213.

Step 1:
When dividing 8 by 155, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 155

Step 2:
86 divided by 155 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 155

Going ahead to step 3:
155 can be fit into 865 5 times, resulting in a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 775 from 865, we get 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 155

Step 4:
155 goes into 906 5 times with a remainder of 131.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtracting 775 from 906 leaves us with 131.
Fetch the next digit (6) from the dividend, attach it to 131 and continue: 1316 / 155

Advancing to step 5:
When dividing 1316 by 155, we get 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 558.0
The remainder is 76 after subtracting 1240 from 1316.
Fetch the next digit (2) from the dividend, attach it to 76 and continue: 762 / 155

On to step 6:
155 can be fit into 762 4 times, resulting in a remainder of 142.
Write down 4 as next digit of the result. 
Result so far: 5584.0
If we subtract 620 from 762, we get 142.
Fetch the next digit (1) from the dividend, attach it to 142 and continue: 1421 / 155

Moving on to step 7:
If we divide 1421 by 155, we get 9 and a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 55849.0
Deduct 1395 from 1421 and we're left with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 155

Advancing to step 8:
155 goes into 263 1 times with a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 558491.0
If we take 155 away from 263, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
1080 divided by 155 is 6 with a remainder of 150.
The next digit of our result is 6. 
Result so far: 558491.6
Subtract 930 from 1080 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
155 can be fit into 1500 9 times, resulting in a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 558491.69
The remainder is 105 after subtracting 1395 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 11:
When dividing 1050 by 155, we get 6 with a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 558491.696
Deduct 930 from 1050 and we're left 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.

Moving on to step 12:
155 goes into 1200 7 times with a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 558491.6967
The remainder is 115 after subtracting 1085 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 13:
155 can be fit into 1150 7 times, resulting in a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 558491.69677
If we take 1085 away from 1150, we end up 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 558491.69677 with a remaining 6.5e-05.
