86123 divided by 99 
Our goal is to divide 86123 by 99.

Going ahead to step 1:
99 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 99

Advancing to step 2:
86 divided by 99 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 99

Advancing to step 3:
99 goes into 861 8 times with a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 792 from 861 leaves us with 69.
Take the next digit (2) from the dividend and append it to 69, then repeat: 692 / 99

Let's proceed to step 4:
99 goes into 692 6 times with a remainder of 98.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Subtracting 594 from 692 leaves us with 98.
Fetch the next digit (3) from the dividend, attach it to 98 and continue: 983 / 99

Advancing to step 5:
The number 99 fits into 983 9 times, leaving a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 869.0
Deduct 891 from 983 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 6:
When dividing 920 by 99, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 869.9
Subtract 891 from 920 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
When dividing 290 by 99, we get 2 with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 869.92
The remainder is 92 after subtracting 198 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 8:
If we divide 920 by 99, we get 9 and a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 869.929
If we take 891 away from 920, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
If we divide 290 by 99, we get 2 and a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 869.9292
Subtracting 198 from 290 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
The number 99 fits into 920 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 869.92929
The remainder is 29 after subtracting 891 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
290 divided by 99 is 2 with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 869.929292
If we subtract 198 from 290, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 12:
99 goes into 920 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 869.9292929
If we subtract 891 from 920, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 13:
99 goes into 290 2 times with a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 869.92929292
If we take 198 away from 290, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The quotient of the division is 869.92929292, and the remainder is 9.2e-08.
