We look at the division of 78509300 by 855 
We want to figure out the number of times 78509300 can be divided by 855.

Moving on to step 1:
When dividing 7 by 855, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 855

Advancing to step 2:
When dividing 78 by 855, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 855

Going ahead to step 3:
The number 855 fits into 785 0 times, leaving a remainder of 785.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 785 and we're left with 785.
Bring next digit (0) of the dividend behind the 785 and repeat the process: 7850 / 855

Let's proceed to step 4:
The number 855 fits into 7850 9 times, leaving a remainder of 155.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 155 after subtracting 7695 from 7850.
Include the next digit (9) from the dividend after 155, then repeat: 1559 / 855

Advancing to step 5:
When dividing 1559 by 855, we get 1 with a remainder of 704.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtracting 855 from 1559 leaves us with 704.
Include the next digit (3) from the dividend after 704, then repeat: 7043 / 855

Step 6:
When dividing 7043 by 855, we get 8 with a remainder of 203.
Record the quotient 8 as the next digit in the result. 
Result so far: 918.0
Deduct 6840 from 7043 and we're left with 203.
Take the next digit (0) from the dividend and append it to 203, then repeat: 2030 / 855

On to step 7:
If we divide 2030 by 855, we get 2 and a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 9182.0
Deduct 1710 from 2030 and we're left with 320.
Bring next digit (0) of the dividend behind the 320 and repeat the process: 3200 / 855

Going ahead to step 8:
The number 855 fits into 3200 3 times, leaving a remainder of 635.
Put 3 as the next digit of the answer. 
Result so far: 91823.0
If we take 2565 away from 3200, we end up with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Moving on to step 9:
855 can be fit into 6350 7 times, resulting in a remainder of 365.
Write down 7 as next digit of the result. 
Result so far: 91823.7
If we take 5985 away from 6350, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 10:
The number 855 fits into 3650 4 times, leaving a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 91823.74
Subtracting 3420 from 3650 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 11:
855 goes into 2300 2 times with a remainder of 590.
Write down 2 as next digit of the result. 
Result so far: 91823.742
Deduct 1710 from 2300 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 12:
When dividing 5900 by 855, we get 6 with a remainder of 770.
The next digit of our result is 6. 
Result so far: 91823.7426
Deduct 5130 from 5900 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 13:
When dividing 7700 by 855, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 91823.74269
Deduct 7695 from 7700 and we're left with 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 14:
If we divide 50 by 855, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 91823.74269
Subtract 0 from 50 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.

Going ahead to step 15:
When dividing 500 by 855, we get 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 91823.74269
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 91823.74269 with a remainder of 5e-06.
