We're dividing 86452036 by 855 
Let's see how many times 855 fits into 86452036.

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
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 855

Step 2:
If we divide 86 by 855, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 855

Moving on to step 3:
The number 855 fits into 864 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 855 from 864, we get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 855

Advancing to step 4:
The number 855 fits into 95 0 times, leaving a remainder of 95.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 95 leaves us with 95.
Bring next digit (2) of the dividend behind the 95 and repeat the process: 952 / 855

Advancing to step 5:
855 can be fit into 952 1 times, resulting in a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 855 from 952 and we're left with 97.
Bring next digit (0) of the dividend behind the 97 and repeat the process: 970 / 855

On to step 6:
When dividing 970 by 855, we get 1 with a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 1011.0
Subtracting 855 from 970 leaves us with 115.
Take the next digit (3) from the dividend and append it to 115, then repeat: 1153 / 855

Moving on to step 7:
The number 855 fits into 1153 1 times, leaving a remainder of 298.
Record the quotient 1 as the next digit in the result. 
Result so far: 10111.0
Subtract 855 from 1153 to get 298.
Bring next digit (6) of the dividend behind the 298 and repeat the process: 2986 / 855

Going ahead to step 8:
The number 855 fits into 2986 3 times, leaving a remainder of 421.
Put 3 as the next digit of the answer. 
Result so far: 101113.0
Subtracting 2565 from 2986 leaves us with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 9:
The number 855 fits into 4210 4 times, leaving a remainder of 790.
Use 4 as the next digit of our solution. 
Result so far: 101113.4
Subtracting 3420 from 4210 leaves us with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 10:
The number 855 fits into 7900 9 times, leaving a remainder of 205.
Record the quotient 9 as the next digit in the result. 
Result so far: 101113.49
Subtracting 7695 from 7900 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 11:
2050 divided by 855 is 2 with a remainder of 340.
Write down 2 as next digit of the result. 
Result so far: 101113.492
If we take 1710 away from 2050, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 12:
855 goes into 3400 3 times with a remainder of 835.
The next digit of our result is 3. 
Result so far: 101113.4923
The remainder is 835 after subtracting 2565 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Going ahead to step 13:
When dividing 8350 by 855, we get 9 with a remainder of 655.
Use 9 as the next digit of our solution. 
Result so far: 101113.49239
If we take 7695 away from 8350, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Going ahead to step 14:
When dividing 6550 by 855, we get 7 with a remainder of 565.
Use 7 as the next digit of our solution. 
Result so far: 101113.492397
Deduct 5985 from 6550 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Let's proceed to step 15:
When dividing 5650 by 855, we get 6 with a remainder of 520.
Use 6 as the next digit of our solution. 
Result so far: 101113.4923976
If we subtract 5130 from 5650, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 16:
855 goes into 5200 6 times with a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 101113.49239766
Subtract 5130 from 5200 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 101113.49239766 and a remainder of 7e-08.
