623137 ÷ 29 
The aim is to understand the frequency of 29 in 623137.

On to step 1:
6 divided by 29 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 29

Moving on to step 2:
If we divide 62 by 29, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 4 after subtracting 58 from 62.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 29

On to step 3:
The number 29 fits into 43 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 29 from 43 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 29

On to step 4:
141 divided by 29 is 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 214.0
The remainder is 25 after subtracting 116 from 141.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 29

Moving on to step 5:
The number 29 fits into 253 8 times, leaving a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 2148.0
Subtracting 232 from 253 leaves us with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 29

Advancing to step 6:
The number 29 fits into 217 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 21487.0
The remainder is 14 after subtracting 203 from 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
29 can be fit into 140 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 21487.4
If we subtract 116 from 140, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
29 goes into 240 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 21487.48
If we take 232 away from 240, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 29, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 21487.482
Deduct 58 from 80 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
29 goes into 220 7 times with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 21487.4827
If we take 203 away from 220, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
170 divided by 29 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 21487.48275
Deduct 145 from 170 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
29 can be fit into 250 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 21487.482758
If we subtract 232 from 250, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
When dividing 180 by 29, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 21487.4827586
Deduct 174 from 180 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.

Moving on to step 14:
If we divide 60 by 29, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 21487.48275862
If we take 58 away from 60, we end up 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.

In conclusion, the division gives 21487.48275862 with a balance of 2e-09.
