743938 divided by 29 
The aim is to understand the frequency of 29 in 743938.

On to step 1:
7 divided by 29 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 29

Step 2:
If we divide 74 by 29, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 58 from 74 leaves us with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 29

Step 3:
29 goes into 163 5 times with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 145 from 163, we get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 29

On to step 4:
If we divide 189 by 29, we get 6 and a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 256.0
Subtracting 174 from 189 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 29

On to step 5:
153 divided by 29 is 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 2565.0
Deduct 145 from 153 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 29

Let's proceed to step 6:
29 goes into 88 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 25653.0
Subtracting 87 from 88 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.

Moving on to step 7:
29 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 25653.0
If we subtract 0 from 10, we 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.

Moving on to step 8:
The number 29 fits into 100 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 25653.03
Subtracting 87 from 100 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
If we divide 130 by 29, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 25653.034
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.

Step 10:
29 goes into 140 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 25653.0344
If we subtract 116 from 140, we 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.

Our division results in 25653.0344 with a remaining 0.00024.
