86855785 divided by 868 
We want to figure out the number of times 86855785 can be divided by 868.

On to step 1:
868 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 868

On to step 2:
86 divided by 868 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 868

Going ahead to step 3:
If we divide 868 by 868, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 868 away from 868, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 868

Advancing to step 4:
The number 868 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 868

Let's proceed to step 5:
The number 868 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 868

On to step 6:
868 can be fit into 557 0 times, resulting in a remainder of 557.
Write down 0 as next digit of the result. 
Result so far: 1000.0
Deduct 0 from 557 and we're left with 557.
Grab the next digit (8) from the dividend, add it to 557, then carry on: 5578 / 868

Going ahead to step 7:
The number 868 fits into 5578 6 times, leaving a remainder of 370.
The number 6 becomes the next digit in our result. 
Result so far: 10006.0
Deduct 5208 from 5578 and we're left with 370.
Append the next digit (5) from the dividend to 370 and continue with: 3705 / 868

Advancing to step 8:
The number 868 fits into 3705 4 times, leaving a remainder of 233.
Record the quotient 4 as the next digit in the result. 
Result so far: 100064.0
If we subtract 3472 from 3705, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 9:
868 can be fit into 2330 2 times, resulting in a remainder of 594.
Put 2 as the next digit of the answer. 
Result so far: 100064.2
If we subtract 1736 from 2330, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 10:
If we divide 5940 by 868, we get 6 and a remainder of 732.
The next digit of our result is 6. 
Result so far: 100064.26
Subtract 5208 from 5940 to get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

On to step 11:
868 goes into 7320 8 times with a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 100064.268
Subtract 6944 from 7320 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 12:
868 goes into 3760 4 times with a remainder of 288.
The next digit of our result is 4. 
Result so far: 100064.2684
Subtracting 3472 from 3760 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 13:
868 can be fit into 2880 3 times, resulting in a remainder of 276.
The next digit of our result is 3. 
Result so far: 100064.26843
If we subtract 2604 from 2880, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 14:
If we divide 2760 by 868, we get 3 and a remainder of 156.
Use 3 as the next digit of our solution. 
Result so far: 100064.268433
If we subtract 2604 from 2760, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Our division results in 100064.268433 with a remaining 1.56e-05.
