We look at the division of 86661556 by 550 
We're looking to find how many times 550 goes into 86661556.

Moving on to step 1:
550 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 550

Let's proceed to step 2:
550 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 550

Step 3:
866 divided by 550 is 1 with a remainder of 316.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 550 from 866 to get 316.
Include the next digit (6) from the dividend after 316, then repeat: 3166 / 550

Advancing to step 4:
550 goes into 3166 5 times with a remainder of 416.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 2750 from 3166 and we're left with 416.
Bring next digit (1) of the dividend behind the 416 and repeat the process: 4161 / 550

Going ahead to step 5:
4161 divided by 550 is 7 with a remainder of 311.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
The remainder is 311 after subtracting 3850 from 4161.
Take the next digit (5) from the dividend and append it to 311, then repeat: 3115 / 550

On to step 6:
550 can be fit into 3115 5 times, resulting in a remainder of 365.
The next digit of our result is 5. 
Result so far: 1575.0
Subtract 2750 from 3115 to get 365.
Include the next digit (5) from the dividend after 365, then repeat: 3655 / 550

Let's proceed to step 7:
3655 divided by 550 is 6 with a remainder of 355.
Use 6 as the next digit of our solution. 
Result so far: 15756.0
Subtracting 3300 from 3655 leaves us with 355.
Fetch the next digit (6) from the dividend, attach it to 355 and continue: 3556 / 550

On to step 8:
3556 divided by 550 is 6 with a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 157566.0
Deduct 3300 from 3556 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 9:
550 can be fit into 2560 4 times, resulting in a remainder of 360.
Put 4 as the next digit of the answer. 
Result so far: 157566.4
If we take 2200 away from 2560, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 10:
3600 divided by 550 is 6 with a remainder of 300.
Use 6 as the next digit of our solution. 
Result so far: 157566.46
Subtract 3300 from 3600 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
3000 divided by 550 is 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 157566.465
Deduct 2750 from 3000 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 12:
When dividing 2500 by 550, we get 4 with a remainder of 300.
The number 4 becomes the next digit in our result. 
Result so far: 157566.4654
Deduct 2200 from 2500 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
The number 550 fits into 3000 5 times, leaving a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 157566.46545
If we take 2750 away from 3000, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 14:
When dividing 2500 by 550, we get 4 with a remainder of 300.
Put 4 as the next digit of the answer. 
Result so far: 157566.465454
Deduct 2200 from 2500 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
550 goes into 3000 5 times with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 157566.4654545
Subtracting 2750 from 3000 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 16:
When dividing 2500 by 550, we get 4 with a remainder of 300.
Write down 4 as next digit of the result. 
Result so far: 157566.46545454
If we subtract 2200 from 2500, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 157566.46545454 with a remaining 3e-07.
