We're dividing 404789 by 29 
The aim is to understand the frequency of 29 in 404789.

Advancing to step 1:
The number 29 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 29

Moving on to step 2:
The number 29 fits into 40 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 29 from 40, we get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 29

On to step 3:
The number 29 fits into 114 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 87 away from 114, we end up with 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 29

Step 4:
If we divide 277 by 29, we get 9 and a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 139.0
If we subtract 261 from 277, we get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 29

Moving on to step 5:
The number 29 fits into 168 5 times, leaving a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 1395.0
Subtracting 145 from 168 leaves us with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 29

On to step 6:
29 goes into 239 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 13958.0
If we subtract 232 from 239, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 29 fits into 70 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 13958.2
The remainder is 12 after subtracting 58 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
29 goes into 120 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 13958.24
If we subtract 116 from 120, we 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.

Advancing to step 9:
When dividing 40 by 29, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 13958.241
The remainder is 11 after subtracting 29 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
29 can be fit into 110 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 13958.2413
Subtracting 87 from 110 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.

On to step 11:
230 divided by 29 is 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 13958.24137
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.

On to step 12:
When dividing 270 by 29, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 13958.241379
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.

Going ahead to step 13:
29 goes into 90 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 13958.2413793
If we take 87 away from 90, we end up 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.

Step 14:
30 divided by 29 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 13958.24137931
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.

Our division results in 13958.24137931 with a remaining 1e-09.
