866790 divided by 55 
Let's see how many times 55 fits into 866790.

Moving on to step 1:
When dividing 8 by 55, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
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 / 55

Let's proceed to step 2:
86 divided by 55 is 1 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.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 55

Advancing to step 3:
55 goes into 316 5 times with a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 275 away from 316, we end up with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 55

Moving on to step 4:
55 can be fit into 417 7 times, resulting in a remainder of 32.
The next digit of our result is 7. 
Result so far: 157.0
Subtract 385 from 417 to get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 55

Going ahead to step 5:
When dividing 329 by 55, we get 5 with a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 1575.0
Subtract 275 from 329 to get 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 55

Step 6:
If we divide 540 by 55, we get 9 and a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 15759.0
If we subtract 495 from 540, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 15759.8
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 55, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 15759.81
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
When dividing 450 by 55, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 15759.818
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 55, we get 1 and a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 15759.8181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 15759.81818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
If we divide 100 by 55, we get 1 and a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 15759.818181
Subtracting 55 from 100 leaves us 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.

Moving on to step 13:
450 divided by 55 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 15759.8181818
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
100 divided by 55 is 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 15759.81818181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 15759.81818181 with a balance of 4.5e-08.
