We're dividing 78464075 by 915 
We want to divide 78464075 by 915.

On to step 1:
7 divided by 915 is 0 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.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 915

Moving on to step 2:
When dividing 78 by 915, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 915

Advancing to step 3:
915 goes into 784 0 times with a remainder of 784.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 784 and we're left with 784.
Include the next digit (6) from the dividend after 784, then repeat: 7846 / 915

Going ahead to step 4:
The number 915 fits into 7846 8 times, leaving a remainder of 526.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7320 from 7846 to get 526.
Append the next digit (4) from the dividend to 526 and continue with: 5264 / 915

Let's proceed to step 5:
If we divide 5264 by 915, we get 5 and a remainder of 689.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
If we take 4575 away from 5264, we end up with 689.
Take the next digit (0) from the dividend and append it to 689, then repeat: 6890 / 915

Going ahead to step 6:
The number 915 fits into 6890 7 times, leaving a remainder of 485.
The next digit of our result is 7. 
Result so far: 857.0
Deduct 6405 from 6890 and we're left with 485.
Append the next digit (7) from the dividend to 485 and continue with: 4857 / 915

On to step 7:
4857 divided by 915 is 5 with a remainder of 282.
Record the quotient 5 as the next digit in the result. 
Result so far: 8575.0
If we take 4575 away from 4857, we end up with 282.
Take the next digit (5) from the dividend and append it to 282, then repeat: 2825 / 915

Step 8:
2825 divided by 915 is 3 with a remainder of 80.
The number 3 becomes the next digit in our result. 
Result so far: 85753.0
If we take 2745 away from 2825, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
800 divided by 915 is 0 with a remainder of 800.
The next digit of our result is 0. 
Result so far: 85753.0
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 10:
915 goes into 8000 8 times with a remainder of 680.
The number 8 becomes the next digit in our result. 
Result so far: 85753.08
Subtract 7320 from 8000 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 11:
915 goes into 6800 7 times with a remainder of 395.
Write down 7 as next digit of the result. 
Result so far: 85753.087
Deduct 6405 from 6800 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 12:
915 can be fit into 3950 4 times, resulting in a remainder of 290.
Put 4 as the next digit of the answer. 
Result so far: 85753.0874
Subtracting 3660 from 3950 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 13:
The number 915 fits into 2900 3 times, leaving a remainder of 155.
Write down 3 as next digit of the result. 
Result so far: 85753.08743
Subtracting 2745 from 2900 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 14:
The number 915 fits into 1550 1 times, leaving a remainder of 635.
Use 1 as the next digit of our solution. 
Result so far: 85753.087431
If we take 915 away from 1550, 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.

Step 15:
6350 divided by 915 is 6 with a remainder of 860.
The next digit of our result is 6. 
Result so far: 85753.0874316
If we take 5490 away from 6350, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Going ahead to step 16:
When dividing 8600 by 915, we get 9 with a remainder of 365.
Record the quotient 9 as the next digit in the result. 
Result so far: 85753.08743169
The remainder is 365 after subtracting 8235 from 8600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The final result is 85753.08743169 with a remainder of 3.65e-07.
