688029 ÷ 29 
The aim is to understand the frequency of 29 in 688029.

Advancing to step 1:
If we divide 6 by 29, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 29

Let's proceed to step 2:
29 goes into 68 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 58 from 68, we get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 29

Advancing to step 3:
108 divided by 29 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 87 from 108, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 29

Let's proceed to step 4:
The number 29 fits into 210 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 237.0
The remainder is 7 after subtracting 203 from 210.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 29

Let's proceed to step 5:
If we divide 72 by 29, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2372.0
Subtracting 58 from 72 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 29

On to step 6:
If we divide 149 by 29, we get 5 and a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 23725.0
Subtract 145 from 149 to get 4.
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:
29 can be fit into 40 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 23725.1
Subtracting 29 from 40 leaves us 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.

On to step 8:
If we divide 110 by 29, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 23725.13
If we take 87 away from 110, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
230 divided by 29 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 23725.137
Deduct 203 from 230 and we're left 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.

Moving on to step 10:
If we divide 270 by 29, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 23725.1379
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
When dividing 90 by 29, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 23725.13793
Deduct 87 from 90 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
29 can be fit into 30 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 23725.137931
Deduct 29 from 30 and we're left 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.

Advancing to step 13:
The number 29 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 23725.137931
Subtracting 0 from 10 leaves us with 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:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 23725.13793103
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.

The final result is 23725.13793103 with a remainder of 1.3e-08.
