We're dividing 903636 by 29 
The aim is to understand the frequency of 29 in 903636.

Step 1:
When dividing 9 by 29, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 29

Let's proceed to step 2:
29 goes into 90 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 87 from 90, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 29

Going ahead to step 3:
When dividing 33 by 29, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 29 from 33, we get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 29

Let's proceed to step 4:
When dividing 46 by 29, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 311.0
If we take 29 away from 46, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 29

Going ahead to step 5:
29 goes into 173 5 times with a remainder of 28.
The next digit of our result is 5. 
Result so far: 3115.0
If we take 145 away from 173, we end up with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 29

Step 6:
When dividing 286 by 29, we get 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 31159.0
If we take 261 away from 286, we end up 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.

Moving on to step 7:
The number 29 fits into 250 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 31159.8
Deduct 232 from 250 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
If we divide 180 by 29, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 31159.86
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.

Let's proceed 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: 31159.862
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.

Advancing to step 10:
The number 29 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 31159.862
If we subtract 0 from 20, we 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.

Going ahead to step 11:
29 goes into 200 6 times with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 31159.86206
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:
260 divided by 29 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 31159.862068
The remainder is 28 after subtracting 232 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
280 divided by 29 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 31159.8620689
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.

On 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: 31159.86206896
If we take 174 away from 190, we end up 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.

After the division, we end up with 31159.86206896 and a remainder of 1.6e-08.
