We look at the division of 310122 by 29 
The aim is to understand the frequency of 29 in 310122.

On to step 1:
3 divided by 29 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 29

Advancing to step 2:
29 goes into 31 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 29 from 31.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 29

Moving on to step 3:
If we divide 20 by 29, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 29

Going ahead to step 4:
When dividing 201 by 29, we get 6 with a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we subtract 174 from 201, we get 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 29

Moving on to step 5:
29 can be fit into 272 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1069.0
Subtract 261 from 272 to get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 29

On to step 6:
The number 29 fits into 112 3 times, leaving a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 10693.0
If we subtract 87 from 112, we get 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:
When dividing 250 by 29, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 10693.8
Subtract 232 from 250 to get 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:
180 divided by 29 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 10693.86
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
When dividing 60 by 29, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 10693.862
If we subtract 58 from 60, we get 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 10:
29 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10693.862
Deduct 0 from 20 and we're left 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:
When dividing 200 by 29, we get 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 10693.86206
Subtracting 174 from 200 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
When dividing 260 by 29, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 10693.862068
Deduct 232 from 260 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
29 can be fit into 280 9 times, resulting in a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 10693.8620689
Subtracting 261 from 280 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
29 goes into 190 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 10693.86206896
If we subtract 174 from 190, we 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.

Our division results in 10693.86206896 with a remaining 1.6e-08.
