We look at the division of 37908 by 29 
The aim is to understand the frequency of 29 in 37908.

Step 1:
If we divide 3 by 29, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 29

Moving on to step 2:
29 can be fit into 37 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 29 from 37 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 29

Let's proceed to step 3:
29 can be fit into 89 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 87 from 89 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 29

On to step 4:
29 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 130.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 29

Moving on to step 5:
208 divided by 29 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 1307.0
The remainder is 5 after subtracting 203 from 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 6:
29 can be fit into 50 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1307.1
If we subtract 29 from 50, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
When dividing 210 by 29, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 1307.17
If we take 203 away from 210, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
70 divided by 29 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1307.172
If we subtract 58 from 70, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
120 divided by 29 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1307.1724
Deduct 116 from 120 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 29 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1307.17241
Subtracting 29 from 40 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
29 goes into 110 3 times with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 1307.172413
Subtract 87 from 110 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
If we divide 230 by 29, we get 7 and a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 1307.1724137
Subtract 203 from 230 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
29 goes into 270 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1307.17241379
Subtracting 261 from 270 leaves us 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.

The final outcome is 1307.17241379, with a leftover of 9e-09.
