We divide 153481 by 43
The aim is to understand the frequency of 43 in 153481.

Step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 43

Going ahead to step 2:
43 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 43

Step 3:
If we divide 153 by 43, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 129 from 153 leaves us with 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 43

On to step 4:
43 goes into 244 5 times with a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 215 away from 244, we end up with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 43

Advancing to step 5:
298 divided by 43 is 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 356.0
Subtracting 258 from 298 leaves us with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 43

On to step 6:
401 divided by 43 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 3569.0
If we subtract 387 from 401, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 43 fits into 140 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3569.3
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
If we divide 110 by 43, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 3569.32
If we subtract 86 from 110, we get 24.
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 9:
When dividing 240 by 43, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 3569.325
Subtracting 215 from 240 leaves us 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.

Going ahead to step 10:
43 goes into 250 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3569.3255
If we take 215 away from 250, we end up 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.

Our division results in 3569.3255 with a remaining 0.00035.
