We're dividing 597645 by 43 
The aim is to understand the frequency of 43 in 597645.

On to step 1:
43 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 43

Moving on to step 2:
59 divided by 43 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 43 away from 59, we end up with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 43

Step 3:
43 can be fit into 167 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 38 after subtracting 129 from 167.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 43

Advancing to step 4:
43 can be fit into 386 8 times, resulting in a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Deduct 344 from 386 and we're left with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 43

Step 5:
424 divided by 43 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 1389.0
Deduct 387 from 424 and we're left with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 43

On to step 6:
The number 43 fits into 375 8 times, leaving a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 13898.0
Deduct 344 from 375 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
43 can be fit into 310 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 13898.7
If we take 301 away from 310, we end up 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.

On to step 8:
When dividing 90 by 43, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 13898.72
Subtracting 86 from 90 leaves us 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.

Let's proceed to step 9:
43 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 13898.72
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 43 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 13898.7209
If we subtract 387 from 400, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
If we divide 130 by 43, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 13898.72093
Subtract 129 from 130 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.

Going ahead to step 12:
43 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13898.72093
If we subtract 0 from 10, we 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.

On to step 13:
When dividing 100 by 43, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 13898.7209302
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 13898.72093023
Subtract 129 from 140 to 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.

The quotient of the division is 13898.72093023, and the remainder is 1.1e-08.
