We look at the division of 99867 by 86 
We want to figure out the number of times 99867 can be divided by 86.

Let's proceed to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 86

Step 2:
86 goes into 99 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 86 from 99 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 86

Let's proceed to step 3:
When dividing 138 by 86, we get 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 86 from 138 and we're left with 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 86

Going ahead to step 4:
When dividing 526 by 86, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we take 516 away from 526, we end up with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 86

Advancing to step 5:
107 divided by 86 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1161.0
If we take 86 away from 107, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 6:
86 can be fit into 210 2 times, resulting in a remainder of 38.
The next digit of our result is 2. 
Result so far: 1161.2
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
86 goes into 380 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 1161.24
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
360 divided by 86 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1161.244
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1161.244, with a leftover of 0.0016.
