Let's divide 87078531 by 855
We're looking to find how many times 855 goes into 87078531.

Going ahead to step 1:
855 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 855

Advancing to step 2:
When dividing 87 by 855, we get 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 855

Advancing to step 3:
855 can be fit into 870 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 855 away from 870, we end up with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 855

Step 4:
157 divided by 855 is 0 with a remainder of 157.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 157 to get 157.
Grab the next digit (8) from the dividend, add it to 157, then carry on: 1578 / 855

Let's proceed to step 5:
The number 855 fits into 1578 1 times, leaving a remainder of 723.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Deduct 855 from 1578 and we're left with 723.
Grab the next digit (5) from the dividend, add it to 723, then carry on: 7235 / 855

On to step 6:
The number 855 fits into 7235 8 times, leaving a remainder of 395.
Record the quotient 8 as the next digit in the result. 
Result so far: 1018.0
If we take 6840 away from 7235, we end up with 395.
Append the next digit (3) from the dividend to 395 and continue with: 3953 / 855

Advancing to step 7:
855 can be fit into 3953 4 times, resulting in a remainder of 533.
Write down 4 as next digit of the result. 
Result so far: 10184.0
Subtracting 3420 from 3953 leaves us with 533.
Fetch the next digit (1) from the dividend, attach it to 533 and continue: 5331 / 855

On to step 8:
855 goes into 5331 6 times with a remainder of 201.
Use 6 as the next digit of our solution. 
Result so far: 101846.0
The remainder is 201 after subtracting 5130 from 5331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 9:
The number 855 fits into 2010 2 times, leaving a remainder of 300.
The next digit of our result is 2. 
Result so far: 101846.2
If we subtract 1710 from 2010, 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.

On to step 10:
855 can be fit into 3000 3 times, resulting in a remainder of 435.
Use 3 as the next digit of our solution. 
Result so far: 101846.23
Subtract 2565 from 3000 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 11:
855 can be fit into 4350 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 101846.235
Deduct 4275 from 4350 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
If we divide 750 by 855, we get 0 and a remainder of 750.
The next digit of our result is 0. 
Result so far: 101846.235
Subtract 0 from 750 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Advancing to step 13:
7500 divided by 855 is 8 with a remainder of 660.
Use 8 as the next digit of our solution. 
Result so far: 101846.23508
Subtracting 6840 from 7500 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 14:
6600 divided by 855 is 7 with a remainder of 615.
The next digit of our result is 7. 
Result so far: 101846.235087
Deduct 5985 from 6600 and we're left with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Let's proceed to step 15:
6150 divided by 855 is 7 with a remainder of 165.
Record the quotient 7 as the next digit in the result. 
Result so far: 101846.2350877
Subtract 5985 from 6150 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Our division results in 101846.2350877 with a remaining 1.65e-06.
