864878 ÷ 55 
Our goal is to divide 864878 by 55.

Step 1:
When dividing 8 by 55, we get 0 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.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 55

Advancing to step 2:
The number 55 fits into 86 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 55 from 86, we get 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 55

Step 3:
The number 55 fits into 314 5 times, leaving a remainder of 39.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 275 from 314 to get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 55

Moving on to step 4:
55 goes into 398 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 157.0
Deduct 385 from 398 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 55

Advancing to step 5:
The number 55 fits into 137 2 times, leaving a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 1572.0
Subtract 110 from 137 to get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 55

Step 6:
55 goes into 278 5 times with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 15725.0
Subtracting 275 from 278 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 55, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 15725.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 55, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 15725.05
Subtract 275 from 300 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
55 can be fit into 250 4 times, resulting in a remainder of 30.
The next digit of our result is 4. 
Result so far: 15725.054
The remainder is 30 after subtracting 220 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
The number 55 fits into 300 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15725.0545
If we take 275 away from 300, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 15725.05454
The remainder is 30 after subtracting 220 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
The number 55 fits into 300 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15725.054545
The remainder is 25 after subtracting 275 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
55 goes into 250 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 15725.0545454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
If we divide 300 by 55, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15725.05454545
If we subtract 275 from 300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 15725.05454545, and the remainder is 2.5e-08.
