We're dividing 503378 by 29 
The aim is to understand the frequency of 29 in 503378.

Advancing to step 1:
29 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 29

On to step 2:
The number 29 fits into 50 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 29 from 50 leaves us with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 29

Let's proceed to step 3:
29 can be fit into 213 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 10 after subtracting 203 from 213.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 29

Step 4:
103 divided by 29 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 173.0
Subtract 87 from 103 to get 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 29

Advancing to step 5:
29 can be fit into 167 5 times, resulting in a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 1735.0
If we subtract 145 from 167, we get 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 29

On to step 6:
If we divide 228 by 29, we get 7 and a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 17357.0
If we take 203 away from 228, we end up 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.

Going ahead to step 7:
29 goes into 250 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 17357.8
Deduct 232 from 250 and we're left with 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 8:
When dividing 180 by 29, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 17357.86
Subtract 174 from 180 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 29, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 17357.862
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.

Let's proceed to step 10:
The number 29 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 17357.862
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
200 divided by 29 is 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 17357.86206
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
260 divided by 29 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 17357.862068
Subtract 232 from 260 to 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.

Moving on to step 13:
280 divided by 29 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 17357.8620689
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
190 divided by 29 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 17357.86206896
Subtract 174 from 190 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 17357.86206896 with a remainder of 1.6e-08.
