We look at the division of 86789994 by 868 
Let's see how many times 868 fits into 86789994.

Step 1:
8 divided by 868 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 868

Step 2:
868 goes into 86 0 times with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 868

Advancing to step 3:
868 can be fit into 867 0 times, resulting in a remainder of 867.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 867, we get 867.
Fetch the next digit (8) from the dividend, attach it to 867 and continue: 8678 / 868

Moving on to step 4:
868 can be fit into 8678 9 times, resulting in a remainder of 866.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 7812 from 8678 leaves us with 866.
Fetch the next digit (9) from the dividend, attach it to 866 and continue: 8669 / 868

Advancing to step 5:
The number 868 fits into 8669 9 times, leaving a remainder of 857.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtracting 7812 from 8669 leaves us with 857.
Grab the next digit (9) from the dividend, add it to 857, then carry on: 8579 / 868

Let's proceed to step 6:
When dividing 8579 by 868, we get 9 with a remainder of 767.
The number 9 becomes the next digit in our result. 
Result so far: 999.0
If we take 7812 away from 8579, we end up with 767.
Include the next digit (9) from the dividend after 767, then repeat: 7679 / 868

Step 7:
The number 868 fits into 7679 8 times, leaving a remainder of 735.
The number 8 becomes the next digit in our result. 
Result so far: 9998.0
If we subtract 6944 from 7679, we get 735.
Fetch the next digit (4) from the dividend, attach it to 735 and continue: 7354 / 868

On to step 8:
868 can be fit into 7354 8 times, resulting in a remainder of 410.
Record the quotient 8 as the next digit in the result. 
Result so far: 99988.0
If we take 6944 away from 7354, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 9:
4100 divided by 868 is 4 with a remainder of 628.
Put 4 as the next digit of the answer. 
Result so far: 99988.4
Deduct 3472 from 4100 and we're left with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 10:
If we divide 6280 by 868, we get 7 and a remainder of 204.
Use 7 as the next digit of our solution. 
Result so far: 99988.47
Deduct 6076 from 6280 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 11:
The number 868 fits into 2040 2 times, leaving a remainder of 304.
Record the quotient 2 as the next digit in the result. 
Result so far: 99988.472
The remainder is 304 after subtracting 1736 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 12:
868 goes into 3040 3 times with a remainder of 436.
Put 3 as the next digit of the answer. 
Result so far: 99988.4723
If we subtract 2604 from 3040, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 13:
868 goes into 4360 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 99988.47235
If we take 4340 away from 4360, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
868 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 99988.47235
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 15:
868 goes into 2000 2 times with a remainder of 264.
The next digit of our result is 2. 
Result so far: 99988.4723502
Subtracting 1736 from 2000 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 16:
The number 868 fits into 2640 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 99988.47235023
The remainder is 36 after subtracting 2604 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 99988.47235023 and a remainder of 3.6e-08.
