Let's divide 861668 by 55
We're looking to find how many times 55 goes into 861668.

On to step 1:
55 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 55

Advancing to step 2:
55 can be fit into 86 1 times, resulting in a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 31 after subtracting 55 from 86.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 55

On to step 3:
55 can be fit into 311 5 times, resulting in a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 275 from 311 and we're left with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 55

On to step 4:
When dividing 366 by 55, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
If we take 330 away from 366, we end up with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 55

Advancing to step 5:
If we divide 366 by 55, we get 6 and a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 1566.0
If we take 330 away from 366, we end up with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 55

Advancing to step 6:
55 goes into 368 6 times with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 15666.0
The remainder is 38 after subtracting 330 from 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
The number 55 fits into 380 6 times, leaving a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 15666.6
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
When dividing 500 by 55, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 15666.69
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 55 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 15666.69
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
When dividing 500 by 55, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 15666.6909
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 15666.6909
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
500 divided by 55 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 15666.690909
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
55 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 15666.690909
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
The number 55 fits into 500 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 15666.69090909
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 15666.69090909 with a remaining 5e-09.
