We're dividing 78310761 by 852 
We want to figure out the number of times 78310761 can be divided by 852.

Step 1:
852 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 852

Moving on to step 2:
852 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 852

Moving on to step 3:
If we divide 783 by 852, we get 0 and a remainder of 783.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 783 to get 783.
Include the next digit (1) from the dividend after 783, then repeat: 7831 / 852

Let's proceed to step 4:
852 can be fit into 7831 9 times, resulting in a remainder of 163.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7668 from 7831, we get 163.
Fetch the next digit (0) from the dividend, attach it to 163 and continue: 1630 / 852

Step 5:
852 goes into 1630 1 times with a remainder of 778.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtract 852 from 1630 to get 778.
Bring next digit (7) of the dividend behind the 778 and repeat the process: 7787 / 852

Going ahead to step 6:
852 goes into 7787 9 times with a remainder of 119.
The next digit of our result is 9. 
Result so far: 919.0
The remainder is 119 after subtracting 7668 from 7787.
Take the next digit (6) from the dividend and append it to 119, then repeat: 1196 / 852

Advancing to step 7:
852 can be fit into 1196 1 times, resulting in a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 9191.0
Subtract 852 from 1196 to get 344.
Take the next digit (1) from the dividend and append it to 344, then repeat: 3441 / 852

Going ahead to step 8:
852 can be fit into 3441 4 times, resulting in a remainder of 33.
The next digit of our result is 4. 
Result so far: 91914.0
If we take 3408 away from 3441, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
If we divide 330 by 852, we get 0 and a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 91914.0
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
852 goes into 3300 3 times with a remainder of 744.
Record the quotient 3 as the next digit in the result. 
Result so far: 91914.03
Subtracting 2556 from 3300 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Step 11:
When dividing 7440 by 852, we get 8 with a remainder of 624.
Write down 8 as next digit of the result. 
Result so far: 91914.038
If we take 6816 away from 7440, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 12:
852 can be fit into 6240 7 times, resulting in a remainder of 276.
The next digit of our result is 7. 
Result so far: 91914.0387
If we subtract 5964 from 6240, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 13:
852 can be fit into 2760 3 times, resulting in a remainder of 204.
Write down 3 as next digit of the result. 
Result so far: 91914.03873
If we subtract 2556 from 2760, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 14:
The number 852 fits into 2040 2 times, leaving a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 91914.038732
Subtract 1704 from 2040 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 15:
852 can be fit into 3360 3 times, resulting in a remainder of 804.
The number 3 becomes the next digit in our result. 
Result so far: 91914.0387323
Deduct 2556 from 3360 and we're left with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

On to step 16:
The number 852 fits into 8040 9 times, leaving a remainder of 372.
Write down 9 as next digit of the result. 
Result so far: 91914.03873239
Subtract 7668 from 8040 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The final outcome is 91914.03873239, with a leftover of 3.72e-07.
