612238 divided by 29 
The aim is to understand the frequency of 29 in 612238.

On to step 1:
29 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 29

Moving on to step 2:
When dividing 61 by 29, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 58 away from 61, we end up with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 29

On to step 3:
The number 29 fits into 32 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 29 from 32 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 29

Let's proceed to step 4:
When dividing 32 by 29, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 211.0
Deduct 29 from 32 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 29

Let's proceed to step 5:
33 divided by 29 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 2111.0
Deduct 29 from 33 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 29

Advancing to step 6:
48 divided by 29 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 21111.0
If we subtract 29 from 48, 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.

Let's proceed to step 7:
29 goes into 190 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 21111.6
Deduct 174 from 190 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
29 goes into 160 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 21111.65
Subtracting 145 from 160 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
If we divide 150 by 29, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 21111.655
Deduct 145 from 150 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 21111.655 with a remaining 0.0005.
