We're dividing 865378 by 55 
We want to divide 865378 by 55.

On to step 1:
55 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 55

Moving on to step 2:
If we divide 86 by 55, we get 1 and a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 55 from 86 and we're left with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 55

Step 3:
When dividing 315 by 55, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 275 away from 315, we end up with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 55

Advancing to step 4:
55 goes into 403 7 times with a remainder of 18.
The next digit of our result is 7. 
Result so far: 157.0
If we take 385 away from 403, we end up with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 55

Advancing to step 5:
187 divided by 55 is 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 1573.0
Subtracting 165 from 187 leaves us with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 55

On to step 6:
228 divided by 55 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 15734.0
Subtracting 220 from 228 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
If we divide 80 by 55, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 15734.1
Subtracting 55 from 80 leaves us 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.

Moving on to step 8:
When dividing 250 by 55, we get 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 15734.14
If we subtract 220 from 250, 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.

Let's proceed to step 9:
300 divided by 55 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15734.145
Deduct 275 from 300 and we're left 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 10:
If we divide 250 by 55, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 15734.1454
Subtracting 220 from 250 leaves us 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.

Moving on to step 11:
When dividing 300 by 55, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 15734.14545
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 12:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 15734.145454
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 13:
55 goes into 300 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15734.1454545
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.

Let's proceed to step 14:
When dividing 250 by 55, we get 4 with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 15734.14545454
Deduct 220 from 250 and we're left 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.

Our division results in 15734.14545454 with a remaining 3e-08.
