Let's divide 75817181 by 878
We want to divide 75817181 by 878.

Step 1:
878 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 878

Moving on to step 2:
If we divide 75 by 878, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 878

Step 3:
The number 878 fits into 758 0 times, leaving a remainder of 758.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 758, we end up with 758.
Grab the next digit (1) from the dividend, add it to 758, then carry on: 7581 / 878

On to step 4:
When dividing 7581 by 878, we get 8 with a remainder of 557.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 557 after subtracting 7024 from 7581.
Append the next digit (7) from the dividend to 557 and continue with: 5577 / 878

Let's proceed to step 5:
878 goes into 5577 6 times with a remainder of 309.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 309 after subtracting 5268 from 5577.
Include the next digit (1) from the dividend after 309, then repeat: 3091 / 878

Moving on to step 6:
If we divide 3091 by 878, we get 3 and a remainder of 457.
The number 3 becomes the next digit in our result. 
Result so far: 863.0
The remainder is 457 after subtracting 2634 from 3091.
Append the next digit (8) from the dividend to 457 and continue with: 4578 / 878

On to step 7:
878 can be fit into 4578 5 times, resulting in a remainder of 188.
Use 5 as the next digit of our solution. 
Result so far: 8635.0
Deduct 4390 from 4578 and we're left with 188.
Take the next digit (1) from the dividend and append it to 188, then repeat: 1881 / 878

Step 8:
The number 878 fits into 1881 2 times, leaving a remainder of 125.
Use 2 as the next digit of our solution. 
Result so far: 86352.0
Subtracting 1756 from 1881 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 9:
When dividing 1250 by 878, we get 1 with a remainder of 372.
Record the quotient 1 as the next digit in the result. 
Result so far: 86352.1
The remainder is 372 after subtracting 878 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 10:
The number 878 fits into 3720 4 times, leaving a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 86352.14
Subtract 3512 from 3720 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 11:
2080 divided by 878 is 2 with a remainder of 324.
Record the quotient 2 as the next digit in the result. 
Result so far: 86352.142
If we take 1756 away from 2080, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 12:
If we divide 3240 by 878, we get 3 and a remainder of 606.
Use 3 as the next digit of our solution. 
Result so far: 86352.1423
Subtracting 2634 from 3240 leaves us with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Step 13:
The number 878 fits into 6060 6 times, leaving a remainder of 792.
Use 6 as the next digit of our solution. 
Result so far: 86352.14236
Deduct 5268 from 6060 and we're left with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

On to step 14:
878 goes into 7920 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 86352.142369
Deduct 7902 from 7920 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 15:
878 goes into 180 0 times with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 86352.142369
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 16:
If we divide 1800 by 878, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 86352.14236902
If we subtract 1756 from 1800, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 86352.14236902 with a remainder of 4.4e-08.
