We're dividing 103402 by 29 
The aim is to understand the frequency of 29 in 103402.

On to step 1:
29 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 29

On to step 2:
When dividing 10 by 29, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 29

Step 3:
When dividing 103 by 29, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 16 after subtracting 87 from 103.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 29

On to step 4:
164 divided by 29 is 5 with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 145 away from 164, we end up with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 29

Moving on to step 5:
When dividing 190 by 29, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 356.0
Subtracting 174 from 190 leaves us with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 29

Moving on to step 6:
The number 29 fits into 162 5 times, leaving a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 3565.0
Subtracting 145 from 162 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
29 goes into 170 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3565.5
The remainder is 25 after subtracting 145 from 170.
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 8:
250 divided by 29 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 3565.58
The remainder is 18 after subtracting 232 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
When dividing 180 by 29, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 3565.586
Subtract 174 from 180 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
60 divided by 29 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 3565.5862
Deduct 58 from 60 and we're left 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.

Going ahead to step 11:
20 divided by 29 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3565.5862
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.

Moving on to step 12:
If we divide 200 by 29, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 3565.586206
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
If we divide 260 by 29, we get 8 and a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 3565.5862068
If we take 232 away from 260, we end up 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.

Advancing to step 14:
The number 29 fits into 280 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 3565.58620689
Deduct 261 from 280 and we're left 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.

Our division results in 3565.58620689 with a remaining 1.9e-08.
