We look at the division of 86871228 by 55 
We want to figure out the number of times 86871228 can be divided by 55.

On to step 1:
55 can be fit into 8 0 times, resulting in 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.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 55

On to step 2:
55 goes into 86 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 31 after subtracting 55 from 86.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 55

Step 3:
318 divided by 55 is 5 with a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 275 from 318 leaves us with 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 55

On to step 4:
If we divide 437 by 55, we get 7 and a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
Deduct 385 from 437 and we're left with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 55

Let's proceed to step 5:
If we divide 521 by 55, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 1579.0
Subtract 495 from 521 to get 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 55

Advancing to step 6:
262 divided by 55 is 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 15794.0
Subtracting 220 from 262 leaves us with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 55

Going ahead to step 7:
55 goes into 422 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 157947.0
The remainder is 37 after subtracting 385 from 422.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 55

Let's proceed to step 8:
55 can be fit into 378 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1579476.0
If we take 330 away from 378, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
The number 55 fits into 480 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 1579476.8
Subtract 440 from 480 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.

Let's proceed to step 10:
400 divided by 55 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 1579476.87
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
55 can be fit into 150 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 1579476.872
Subtract 110 from 150 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 12:
If we divide 400 by 55, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 1579476.8727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
150 divided by 55 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 1579476.87272
If we take 110 away from 150, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 1579476.872727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 15:
The number 55 fits into 150 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 1579476.8727272
Subtract 110 from 150 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.

Step 16:
55 goes into 400 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 1579476.87272727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 1579476.87272727, with a leftover of 1.5e-08.
