We look at the division of 857369 by 29 
The aim is to understand the frequency of 29 in 857369.

Moving on to step 1:
29 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 29

Advancing to step 2:
The number 29 fits into 85 2 times, leaving a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 27 after subtracting 58 from 85.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 29

Moving on to step 3:
If we divide 277 by 29, we get 9 and a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 16 after subtracting 261 from 277.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 29

Going ahead to step 4:
163 divided by 29 is 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 295.0
Subtract 145 from 163 to get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 29

Going ahead to step 5:
If we divide 186 by 29, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 2956.0
The remainder is 12 after subtracting 174 from 186.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 29

Moving on to step 6:
When dividing 129 by 29, we get 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 29564.0
If we take 116 away from 129, we end up 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.

Let's proceed to step 7:
130 divided by 29 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 29564.4
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.

Advancing to step 8:
140 divided by 29 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 29564.44
Subtracting 116 from 140 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 29564.44, and the remainder is 0.024.
