We're dividing 29600123 by 123 
The aim is to understand the frequency of 123 in 29600123.

Going ahead to step 1:
When dividing 2 by 123, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 123

Advancing to step 2:
When dividing 29 by 123, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 123

Going ahead to step 3:
The number 123 fits into 296 2 times, leaving a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 246 from 296 leaves us with 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 123

Moving on to step 4:
123 can be fit into 500 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 492 from 500 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 123

On to step 5:
80 divided by 123 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 240.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 123

Let's proceed to step 6:
When dividing 801 by 123, we get 6 with a remainder of 63.
Record the quotient 6 as the next digit in the result. 
Result so far: 2406.0
Subtracting 738 from 801 leaves us with 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 123

Moving on to step 7:
123 can be fit into 632 5 times, resulting in a remainder of 17.
The next digit of our result is 5. 
Result so far: 24065.0
Subtract 615 from 632 to get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 123

Let's proceed to step 8:
The number 123 fits into 173 1 times, leaving a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 240651.0
If we take 123 away from 173, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
123 can be fit into 500 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 240651.4
Deduct 492 from 500 and we're left 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.

Let's proceed to step 10:
The number 123 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 240651.4
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
123 can be fit into 800 6 times, resulting in a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 240651.406
If we subtract 738 from 800, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
When dividing 620 by 123, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 240651.4065
If we take 615 away from 620, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
123 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 240651.4065
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
123 can be fit into 500 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 240651.406504
Deduct 492 from 500 and we're left 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.

Advancing to step 15:
123 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 240651.406504
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
800 divided by 123 is 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 240651.40650406
Subtracting 738 from 800 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 240651.40650406 and a remainder of 6.2e-08.
