Let's divide 303290 by 29
The aim is to understand the frequency of 29 in 303290.

Advancing to step 1:
3 divided by 29 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 29

Moving on to step 2:
The number 29 fits into 30 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 29 from 30 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 29

Step 3:
When dividing 13 by 29, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 29

Let's proceed to step 4:
29 goes into 132 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 104.0
If we take 116 away from 132, we end up with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 29

Let's proceed to step 5:
29 can be fit into 169 5 times, resulting in a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 1045.0
If we take 145 away from 169, we end up with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 29

On to step 6:
If we divide 240 by 29, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 10458.0
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.

On to step 7:
80 divided by 29 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 10458.2
Subtracting 58 from 80 leaves us 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.

Moving on to step 8:
If we divide 220 by 29, we get 7 and a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 10458.27
The remainder is 17 after subtracting 203 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
29 goes into 170 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10458.275
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 10:
When dividing 250 by 29, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 10458.2758
The remainder is 18 after subtracting 232 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
29 can be fit into 180 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 10458.27586
If we subtract 174 from 180, we 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.

Advancing to step 12:
29 goes into 60 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 10458.275862
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.

Step 13:
29 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10458.275862
Subtract 0 from 20 to get 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 14:
29 goes into 200 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 10458.27586206
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.

The quotient of the division is 10458.27586206, and the remainder is 2.6e-08.
