We look at the division of 688611 by 29 
The aim is to understand the frequency of 29 in 688611.

Step 1:
29 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 29

On to step 2:
When dividing 68 by 29, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 10 after subtracting 58 from 68.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 29

Going ahead to step 3:
29 goes into 108 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 87 from 108, we get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 29

Moving on to step 4:
29 can be fit into 216 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 237.0
Subtract 203 from 216 to get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 29

Moving on to step 5:
If we divide 131 by 29, we get 4 and a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 2374.0
The remainder is 15 after subtracting 116 from 131.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 29

Advancing to step 6:
29 can be fit into 151 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 23745.0
Deduct 145 from 151 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 29 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 23745.2
Subtracting 58 from 60 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 29 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 23745.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
29 goes into 200 6 times with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 23745.206
Subtracting 174 from 200 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
When dividing 260 by 29, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 23745.2068
If we subtract 232 from 260, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
29 can be fit into 280 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 23745.20689
If we take 261 away from 280, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
29 can be fit into 190 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 23745.206896
Subtracting 174 from 190 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
29 can be fit into 160 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 23745.2068965
The remainder is 15 after subtracting 145 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
29 can be fit into 150 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 23745.20689655
Subtract 145 from 150 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 23745.20689655 with a remainder of 5e-09.
