We look at the division of 428040 by 29 
The aim is to understand the frequency of 29 in 428040.

On to step 1:
The number 29 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 29

On to step 2:
The number 29 fits into 42 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 29 from 42 leaves us with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 29

Advancing to step 3:
29 goes into 138 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 116 from 138 and we're left with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 29

Step 4:
When dividing 220 by 29, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 147.0
If we subtract 203 from 220, we get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 29

Going ahead to step 5:
29 can be fit into 174 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1476.0
Subtracting 174 from 174 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 29

Let's proceed to step 6:
29 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14760.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
The number 29 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 14760.0
Subtracting 0 from 0 leaves us 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.

Going ahead to step 8:
If we divide 0 by 29, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 14760.0
Deduct 0 from 0 and we're left 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.

The quotient of the division is 14760.0, and the remainder is 0.0.
