We're dividing 85178478 by 855 
Our goal is to divide 85178478 by 855.

Going ahead to step 1:
855 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 855

On to step 2:
When dividing 85 by 855, we get 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 855

Advancing to step 3:
The number 855 fits into 851 0 times, leaving a remainder of 851.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 851 after subtracting 0 from 851.
Fetch the next digit (7) from the dividend, attach it to 851 and continue: 8517 / 855

Going ahead to step 4:
When dividing 8517 by 855, we get 9 with a remainder of 822.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7695 from 8517 and we're left with 822.
Take the next digit (8) from the dividend and append it to 822, then repeat: 8228 / 855

Let's proceed to step 5:
When dividing 8228 by 855, we get 9 with a remainder of 533.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 7695 from 8228 to get 533.
Take the next digit (4) from the dividend and append it to 533, then repeat: 5334 / 855

Going ahead to step 6:
If we divide 5334 by 855, we get 6 and a remainder of 204.
The next digit of our result is 6. 
Result so far: 996.0
If we subtract 5130 from 5334, we get 204.
Bring next digit (7) of the dividend behind the 204 and repeat the process: 2047 / 855

Going ahead to step 7:
If we divide 2047 by 855, we get 2 and a remainder of 337.
Record the quotient 2 as the next digit in the result. 
Result so far: 9962.0
Subtracting 1710 from 2047 leaves us with 337.
Append the next digit (8) from the dividend to 337 and continue with: 3378 / 855

Moving on to step 8:
If we divide 3378 by 855, we get 3 and a remainder of 813.
The number 3 becomes the next digit in our result. 
Result so far: 99623.0
The remainder is 813 after subtracting 2565 from 3378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

On to step 9:
If we divide 8130 by 855, we get 9 and a remainder of 435.
Put 9 as the next digit of the answer. 
Result so far: 99623.9
Subtract 7695 from 8130 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.

Advancing to step 10:
The number 855 fits into 4350 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 99623.95
Subtract 4275 from 4350 to get 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 11:
855 can be fit into 750 0 times, resulting in a remainder of 750.
Record the quotient 0 as the next digit in the result. 
Result so far: 99623.95
Deduct 0 from 750 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 12:
When dividing 7500 by 855, we get 8 with a remainder of 660.
The number 8 becomes the next digit in our result. 
Result so far: 99623.9508
Subtract 6840 from 7500 to get 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 13:
6600 divided by 855 is 7 with a remainder of 615.
Put 7 as the next digit of the answer. 
Result so far: 99623.95087
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.

On to step 14:
When dividing 6150 by 855, we get 7 with a remainder of 165.
Record the quotient 7 as the next digit in the result. 
Result so far: 99623.950877
Deduct 5985 from 6150 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final result is 99623.950877 with a remainder of 1.65e-05.
