We're dividing 86496866 by 878 
Let's see how many times 878 fits into 86496866.

Let's proceed to step 1:
If we divide 8 by 878, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 878

Step 2:
86 divided by 878 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 878

Advancing to step 3:
The number 878 fits into 864 0 times, leaving a remainder of 864.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 864 and we're left with 864.
Grab the next digit (9) from the dividend, add it to 864, then carry on: 8649 / 878

Step 4:
When dividing 8649 by 878, we get 9 with a remainder of 747.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7902 away from 8649, we end up with 747.
Take the next digit (6) from the dividend and append it to 747, then repeat: 7476 / 878

On to step 5:
The number 878 fits into 7476 8 times, leaving a remainder of 452.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 7024 from 7476 and we're left with 452.
Append the next digit (8) from the dividend to 452 and continue with: 4528 / 878

Going ahead to step 6:
878 can be fit into 4528 5 times, resulting in a remainder of 138.
The number 5 becomes the next digit in our result. 
Result so far: 985.0
Subtracting 4390 from 4528 leaves us with 138.
Grab the next digit (6) from the dividend, add it to 138, then carry on: 1386 / 878

Moving on to step 7:
If we divide 1386 by 878, we get 1 and a remainder of 508.
The next digit of our result is 1. 
Result so far: 9851.0
Subtracting 878 from 1386 leaves us with 508.
Include the next digit (6) from the dividend after 508, then repeat: 5086 / 878

Going ahead to step 8:
The number 878 fits into 5086 5 times, leaving a remainder of 696.
Record the quotient 5 as the next digit in the result. 
Result so far: 98515.0
Subtract 4390 from 5086 to get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 9:
878 goes into 6960 7 times with a remainder of 814.
The number 7 becomes the next digit in our result. 
Result so far: 98515.7
If we take 6146 away from 6960, we end up with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Moving on to step 10:
878 goes into 8140 9 times with a remainder of 238.
Record the quotient 9 as the next digit in the result. 
Result so far: 98515.79
Subtract 7902 from 8140 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 11:
2380 divided by 878 is 2 with a remainder of 624.
Record the quotient 2 as the next digit in the result. 
Result so far: 98515.792
Subtract 1756 from 2380 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 12:
878 goes into 6240 7 times with a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 98515.7927
The remainder is 94 after subtracting 6146 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 13:
The number 878 fits into 940 1 times, leaving a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 98515.79271
If we subtract 878 from 940, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
The number 878 fits into 620 0 times, leaving a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 98515.79271
Deduct 0 from 620 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 15:
The number 878 fits into 6200 7 times, leaving a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 98515.7927107
The remainder is 54 after subtracting 6146 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 16:
When dividing 540 by 878, we get 0 with a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 98515.7927107
If we subtract 0 from 540, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

After the division, we end up with 98515.7927107 and a remainder of 5.4e-07.
