869569 ÷ 29 
The aim is to understand the frequency of 29 in 869569.

Advancing to step 1:
The number 29 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 29

Moving on to step 2:
86 divided by 29 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 58 from 86 leaves us with 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 29

Going ahead to step 3:
29 goes into 289 9 times with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 261 from 289 leaves us with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 29

Moving on to step 4:
29 goes into 285 9 times with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 299.0
If we take 261 away from 285, we end up with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 29

Going ahead to step 5:
246 divided by 29 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 2998.0
The remainder is 14 after subtracting 232 from 246.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 29

Advancing to step 6:
If we divide 149 by 29, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 29985.0
The remainder is 4 after subtracting 145 from 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
The number 29 fits into 40 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 29985.1
If we take 29 away from 40, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
110 divided by 29 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 29985.13
The remainder is 23 after subtracting 87 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
29 goes into 230 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 29985.137
Subtracting 203 from 230 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
The number 29 fits into 270 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 29985.1379
If we take 261 away from 270, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
The number 29 fits into 90 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 29985.13793
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
The number 29 fits into 30 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 29985.137931
Subtract 29 from 30 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
29 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 29985.137931
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.

Advancing to step 14:
The number 29 fits into 100 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 29985.13793103
Subtract 87 from 100 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 29985.13793103 with a remainder of 1.3e-08.
