We're dividing 169335 by 43 
The aim is to understand the frequency of 43 in 169335.

On to step 1:
43 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.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 43

Going ahead to step 2:
43 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 43

Advancing to step 3:
The number 43 fits into 169 3 times, leaving a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 129 from 169 and we're left with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 43

Step 4:
If we divide 403 by 43, we get 9 and a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 387 away from 403, we end up with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 43

On to step 5:
When dividing 163 by 43, we get 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 393.0
Subtract 129 from 163 to get 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 43

On to step 6:
The number 43 fits into 345 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 3938.0
Subtract 344 from 345 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 43, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 3938.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 43 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 3938.02
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3938.023
If we take 129 away from 140, we end up 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.

Advancing to step 10:
110 divided by 43 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 3938.0232
The remainder is 24 after subtracting 86 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
240 divided by 43 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 3938.02325
If we take 215 away from 240, 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.

Advancing to step 12:
43 goes into 250 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 3938.023255
Deduct 215 from 250 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 3938.023255, with a leftover of 3.5e-06.
