We're dividing 503480 by 29 
The aim is to understand the frequency of 29 in 503480.

On to step 1:
29 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 29

Step 2:
29 goes into 50 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 29 from 50, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 29

Going ahead to step 3:
When dividing 213 by 29, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 203 from 213 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 29

Advancing to step 4:
The number 29 fits into 104 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
Deduct 87 from 104 and we're left with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 29

Moving on to step 5:
29 goes into 178 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1736.0
Subtract 174 from 178 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 29

Advancing to step 6:
If we divide 40 by 29, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 17361.0
Subtract 29 from 40 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
29 goes into 110 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 17361.3
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.

Advancing to step 8:
29 can be fit into 230 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 17361.37
Subtract 203 from 230 to 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.

Going ahead to step 9:
29 goes into 270 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 17361.379
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 10:
When dividing 90 by 29, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 17361.3793
If we subtract 87 from 90, we 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 11:
30 divided by 29 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 17361.37931
The remainder is 1 after subtracting 29 from 30.
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 12:
When dividing 10 by 29, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 17361.37931
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 17361.3793103
Deduct 87 from 100 and we're left 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.

Let's proceed to step 14:
29 can be fit into 130 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 17361.37931034
The remainder is 14 after subtracting 116 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 17361.37931034 and a remainder of 1.4e-08.
