We look at the division of 809645 by 29 
The aim is to understand the frequency of 29 in 809645.

Step 1:
8 divided by 29 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 29

On to step 2:
When dividing 80 by 29, we get 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 58 from 80 and we're left with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 29

On to step 3:
29 can be fit into 229 7 times, resulting in a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 203 away from 229, we end up with 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 29

Moving on to step 4:
The number 29 fits into 266 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.0
If we subtract 261 from 266, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 29

On to step 5:
When dividing 54 by 29, we get 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 2791.0
Subtract 29 from 54 to get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 29

Moving on to step 6:
When dividing 255 by 29, we get 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 27918.0
Subtracting 232 from 255 leaves us 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.

Let's proceed to step 7:
If we divide 230 by 29, we get 7 and a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 27918.7
If we subtract 203 from 230, we get 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 8:
29 goes into 270 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 27918.79
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.

Let's proceed to step 9:
The number 29 fits into 90 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 27918.793
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.

Going ahead to step 10:
When dividing 30 by 29, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 27918.7931
Subtracting 29 from 30 leaves us 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.

On to step 11:
10 divided by 29 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 27918.7931
If we take 0 away from 10, we end up 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.

Let's proceed to step 12:
If we divide 100 by 29, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 27918.793103
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.

On to step 13:
130 divided by 29 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 27918.7931034
Subtract 116 from 130 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
The number 29 fits into 140 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 27918.79310344
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.

After the division, we end up with 27918.79310344 and a remainder of 2.4e-08.
