We look at the division of 148717 by 29 
The aim is to understand the frequency of 29 in 148717.

Advancing to step 1:
The number 29 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 29

Going ahead to step 2:
The number 29 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 29

Step 3:
29 goes into 148 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 145 from 148 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 29

Step 4:
37 divided by 29 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 51.0
Deduct 29 from 37 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 29

Moving on to step 5:
29 can be fit into 81 2 times, resulting in a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 512.0
Subtract 58 from 81 to get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 29

Going ahead to step 6:
The number 29 fits into 237 8 times, leaving a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 5128.0
Subtracting 232 from 237 leaves us 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.

On to step 7:
The number 29 fits into 50 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 5128.1
Subtracting 29 from 50 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
If we divide 210 by 29, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 5128.17
Subtract 203 from 210 to get 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 9:
29 can be fit into 70 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 5128.172
If we take 58 away from 70, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
The number 29 fits into 120 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 5128.1724
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 11:
29 can be fit into 40 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 5128.17241
The remainder is 11 after subtracting 29 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
110 divided by 29 is 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 5128.172413
The remainder is 23 after subtracting 87 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
When dividing 230 by 29, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 5128.1724137
Deduct 203 from 230 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
29 goes into 270 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 5128.17241379
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.

The final outcome is 5128.17241379, with a leftover of 9e-09.
