123657 ÷ 29 
The aim is to understand the frequency of 29 in 123657.

Let's proceed to step 1:
29 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 29

On to step 2:
29 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 29

Step 3:
29 can be fit into 123 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 116 from 123 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 29

On to step 4:
29 can be fit into 76 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 58 from 76 to get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 29

Advancing to step 5:
185 divided by 29 is 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 426.0
If we take 174 away from 185, we end up with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 29

On to step 6:
If we divide 117 by 29, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4264.0
Subtracting 116 from 117 leaves us 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.

Advancing to step 7:
29 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4264.0
Subtract 0 from 10 to get 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:
29 goes into 100 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 4264.03
The remainder is 13 after subtracting 87 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 29 fits into 130 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4264.034
Subtracting 116 from 130 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
If we divide 140 by 29, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4264.0344
Subtract 116 from 140 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 4264.0344 and a remainder of 0.00024.
