We divide 537737 by 43
The aim is to understand the frequency of 43 in 537737.

Step 1:
43 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 43

Advancing to step 2:
If we divide 53 by 43, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 10 after subtracting 43 from 53.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 43

Moving on to step 3:
107 divided by 43 is 2 with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 86 from 107 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 43

Going ahead to step 4:
43 can be fit into 217 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 125.0
Subtract 215 from 217 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 43

Going ahead to step 5:
When dividing 23 by 43, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 1250.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 43

Step 6:
43 can be fit into 237 5 times, resulting in a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 12505.0
The remainder is 22 after subtracting 215 from 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
43 goes into 220 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 12505.5
If we take 215 away from 220, we end up 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.

Let's proceed to step 8:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 12505.51
If we take 43 away from 50, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
The number 43 fits into 70 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 12505.511
If we subtract 43 from 70, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 12505.511 with a balance of 0.0027.
