We're dividing 78151035 by 935 
We want to divide 78151035 by 935.

Going ahead to step 1:
935 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 935

Step 2:
78 divided by 935 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 935

Advancing to step 3:
When dividing 781 by 935, we get 0 with a remainder of 781.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 781 and we're left with 781.
Take the next digit (5) from the dividend and append it to 781, then repeat: 7815 / 935

Let's proceed to step 4:
7815 divided by 935 is 8 with a remainder of 335.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 335 after subtracting 7480 from 7815.
Take the next digit (1) from the dividend and append it to 335, then repeat: 3351 / 935

Moving on to step 5:
The number 935 fits into 3351 3 times, leaving a remainder of 546.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Subtracting 2805 from 3351 leaves us with 546.
Fetch the next digit (0) from the dividend, attach it to 546 and continue: 5460 / 935

Going ahead to step 6:
The number 935 fits into 5460 5 times, leaving a remainder of 785.
The next digit of our result is 5. 
Result so far: 835.0
Deduct 4675 from 5460 and we're left with 785.
Include the next digit (3) from the dividend after 785, then repeat: 7853 / 935

Going ahead to step 7:
935 goes into 7853 8 times with a remainder of 373.
Record the quotient 8 as the next digit in the result. 
Result so far: 8358.0
If we subtract 7480 from 7853, we get 373.
Append the next digit (5) from the dividend to 373 and continue with: 3735 / 935

On to step 8:
The number 935 fits into 3735 3 times, leaving a remainder of 930.
The number 3 becomes the next digit in our result. 
Result so far: 83583.0
If we subtract 2805 from 3735, we get 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9300, and continue the process.

Moving on to step 9:
When dividing 9300 by 935, we get 9 with a remainder of 885.
Put 9 as the next digit of the answer. 
Result so far: 83583.9
Deduct 8415 from 9300 and we're left with 885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8850, and continue the process.

Advancing to step 10:
935 can be fit into 8850 9 times, resulting in a remainder of 435.
Put 9 as the next digit of the answer. 
Result so far: 83583.99
Subtracting 8415 from 8850 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Our division results in 83583.99 with a remaining 0.435.
