Let's divide 123396 by 23
We're looking to find how many times 23 goes into 123396.

Going ahead to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 23

On to step 2:
When dividing 12 by 23, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 23

Advancing to step 3:
23 can be fit into 123 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
If we take 115 away from 123, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 23

Moving on to step 4:
23 can be fit into 83 3 times, resulting in a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we subtract 69 from 83, we get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 23

Moving on to step 5:
149 divided by 23 is 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 536.0
The remainder is 11 after subtracting 138 from 149.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 23

Advancing to step 6:
When dividing 116 by 23, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5365.0
Deduct 115 from 116 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 23 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 5365.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 23, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5365.04
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
23 goes into 80 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 5365.043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
23 goes into 110 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 5365.0434
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
23 goes into 180 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 5365.04347
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
If we divide 190 by 23, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 5365.043478
If we take 184 away from 190, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
23 can be fit into 60 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 5365.0434782
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
The number 23 fits into 140 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 5365.04347826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 5365.04347826, and the remainder is 2e-09.
