We divide 78485513 by 866
We're looking to find how many times 866 goes into 78485513.

Moving on to step 1:
866 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 866

Let's proceed to step 2:
The number 866 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 866

Let's proceed to step 3:
866 goes into 784 0 times with a remainder of 784.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 784 leaves us with 784.
Fetch the next digit (8) from the dividend, attach it to 784 and continue: 7848 / 866

Step 4:
The number 866 fits into 7848 9 times, leaving a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 7794 from 7848 leaves us with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 866

Advancing to step 5:
The number 866 fits into 545 0 times, leaving a remainder of 545.
Put 0 as the next digit of the answer. 
Result so far: 90.0
If we subtract 0 from 545, we get 545.
Take the next digit (5) from the dividend and append it to 545, then repeat: 5455 / 866

On to step 6:
When dividing 5455 by 866, we get 6 with a remainder of 259.
The next digit of our result is 6. 
Result so far: 906.0
If we take 5196 away from 5455, we end up with 259.
Grab the next digit (1) from the dividend, add it to 259, then carry on: 2591 / 866

Going ahead to step 7:
When dividing 2591 by 866, we get 2 with a remainder of 859.
Record the quotient 2 as the next digit in the result. 
Result so far: 9062.0
If we subtract 1732 from 2591, we get 859.
Bring next digit (3) of the dividend behind the 859 and repeat the process: 8593 / 866

Let's proceed to step 8:
866 can be fit into 8593 9 times, resulting in a remainder of 799.
Write down 9 as next digit of the result. 
Result so far: 90629.0
Subtract 7794 from 8593 to get 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

On to step 9:
866 can be fit into 7990 9 times, resulting in a remainder of 196.
The number 9 becomes the next digit in our result. 
Result so far: 90629.9
If we take 7794 away from 7990, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 10:
If we divide 1960 by 866, we get 2 and a remainder of 228.
Put 2 as the next digit of the answer. 
Result so far: 90629.92
Subtract 1732 from 1960 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
866 can be fit into 2280 2 times, resulting in a remainder of 548.
Use 2 as the next digit of our solution. 
Result so far: 90629.922
The remainder is 548 after subtracting 1732 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

The final result is 90629.922 with a remainder of 0.0548.
