We're dividing 78511113 by 868 
We want to divide 78511113 by 868.

Advancing to step 1:
If we divide 7 by 868, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 868

Going ahead to step 2:
The number 868 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 868

Advancing to step 3:
The number 868 fits into 785 0 times, leaving a remainder of 785.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 785 leaves us with 785.
Append the next digit (1) from the dividend to 785 and continue with: 7851 / 868

Going ahead to step 4:
The number 868 fits into 7851 9 times, leaving a remainder of 39.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7812 from 7851 and we're left with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 868

Going ahead to step 5:
391 divided by 868 is 0 with a remainder of 391.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
The remainder is 391 after subtracting 0 from 391.
Grab the next digit (1) from the dividend, add it to 391, then carry on: 3911 / 868

Moving on to step 6:
The number 868 fits into 3911 4 times, leaving a remainder of 439.
Put 4 as the next digit of the answer. 
Result so far: 904.0
The remainder is 439 after subtracting 3472 from 3911.
Fetch the next digit (1) from the dividend, attach it to 439 and continue: 4391 / 868

Step 7:
868 goes into 4391 5 times with a remainder of 51.
The next digit of our result is 5. 
Result so far: 9045.0
Subtracting 4340 from 4391 leaves us with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 868

Advancing to step 8:
868 goes into 513 0 times with a remainder of 513.
The number 0 becomes the next digit in our result. 
Result so far: 90450.0
Deduct 0 from 513 and we're left with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Let's proceed to step 9:
868 goes into 5130 5 times with a remainder of 790.
The next digit of our result is 5. 
Result so far: 90450.5
Subtract 4340 from 5130 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 10:
If we divide 7900 by 868, we get 9 and a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 90450.59
Deduct 7812 from 7900 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
The number 868 fits into 880 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 90450.591
Subtracting 868 from 880 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
868 goes into 120 0 times with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 90450.591
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
1200 divided by 868 is 1 with a remainder of 332.
Put 1 as the next digit of the answer. 
Result so far: 90450.59101
Subtracting 868 from 1200 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 14:
868 can be fit into 3320 3 times, resulting in a remainder of 716.
Put 3 as the next digit of the answer. 
Result so far: 90450.591013
Subtract 2604 from 3320 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Moving on to step 15:
When dividing 7160 by 868, we get 8 with a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 90450.5910138
The remainder is 216 after subtracting 6944 from 7160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 16:
2160 divided by 868 is 2 with a remainder of 424.
Write down 2 as next digit of the result. 
Result so far: 90450.59101382
Subtract 1736 from 2160 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Our division results in 90450.59101382 with a remaining 4.24e-07.
