We're dividing 868520 by 55 
We want to figure out the number of times 868520 can be divided by 55.

Step 1:
55 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 55

Going ahead to step 2:
86 divided by 55 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 55 from 86, we get 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 55

Moving on to step 3:
When dividing 318 by 55, we get 5 with a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 275 from 318 leaves us with 43.
Bring next digit (5) of the dividend behind the 43 and repeat the process: 435 / 55

On to step 4:
55 goes into 435 7 times with a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Deduct 385 from 435 and we're left with 50.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 55

Advancing to step 5:
55 goes into 502 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1579.0
If we subtract 495 from 502, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 55

Step 6:
70 divided by 55 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 15791.0
The remainder is 15 after subtracting 55 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
150 divided by 55 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 15791.2
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.

Going ahead to step 8:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 15791.27
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 9:
55 goes into 150 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 15791.272
If we subtract 110 from 150, we 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 10:
The number 55 fits into 400 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 15791.2727
If we take 385 away from 400, we end up 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.

Going ahead to step 11:
55 goes into 150 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 15791.27272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

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: 15791.272727
If we take 385 away from 400, we end up 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.

Advancing to step 13:
If we divide 150 by 55, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 15791.2727272
Subtracting 110 from 150 leaves us 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.

Let's proceed to step 14:
55 goes into 400 7 times with a remainder of 15.
The next digit of our result is 7. 
Result so far: 15791.27272727
If we take 385 away from 400, we end up 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.

Our division results in 15791.27272727 with a remaining 1.5e-08.
