Let's divide 102321 by 12
Let's see how many times 12 fits into 102321.

Going ahead to step 1:
1 divided by 12 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 12

On to step 2:
10 divided by 12 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 12

Advancing to step 3:
102 divided by 12 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 96 from 102 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 12

Moving on to step 4:
63 divided by 12 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 60 from 63 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 12

Going ahead to step 5:
If we divide 32 by 12, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 852.0
If we take 24 away from 32, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 12

Advancing to step 6:
12 goes into 81 6 times with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 8526.0
If we subtract 72 from 81, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
12 can be fit into 90 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 8526.7
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8526.75
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8526.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8526.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8526.75 and a remainder of 0.0.
