We look at the division of 290270 by 29 
The aim is to understand the frequency of 29 in 290270.

Advancing to step 1:
29 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 29

Advancing to step 2:
When dividing 29 by 29, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 29 from 29 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 29

Moving on to step 3:
29 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 29

Going ahead to step 4:
The number 29 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 29

Advancing to step 5:
If we divide 27 by 29, we get 0 and a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 1000.0
If we take 0 away from 27, we end up with 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 29

Going ahead to step 6:
If we divide 270 by 29, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 10009.0
Deduct 261 from 270 and we're left 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.

Going ahead to step 7:
When dividing 90 by 29, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 10009.3
Deduct 87 from 90 and we're left 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.

On to step 8:
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: 10009.31
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.

Let's proceed to step 9:
If we divide 10 by 29, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10009.31
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.

On to step 10:
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: 10009.3103
The remainder is 13 after subtracting 87 from 100.
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 11:
When dividing 130 by 29, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 10009.31034
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.

Step 12:
When dividing 140 by 29, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 10009.310344
Deduct 116 from 140 and we're left 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.

The final outcome is 10009.310344, with a leftover of 2.4e-06.
