We look at the division of 960161 by 43 
The aim is to understand the frequency of 43 in 960161.

Moving on to step 1:
43 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 43

Step 2:
43 goes into 96 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 10 after subtracting 86 from 96.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 43

Advancing to step 3:
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: 22.0
Subtracting 86 from 100 leaves us with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 43

Moving on to step 4:
When dividing 141 by 43, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 223.0
Deduct 129 from 141 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 43

On to step 5:
43 can be fit into 126 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2232.0
The remainder is 40 after subtracting 86 from 126.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 43

Advancing to step 6:
The number 43 fits into 401 9 times, leaving a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 22329.0
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.

Step 7:
43 goes into 140 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 22329.3
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.

On to step 8:
110 divided by 43 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 22329.32
Subtract 86 from 110 to 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.

On to step 9:
43 can be fit into 240 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 22329.325
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.

Moving on to step 10:
When dividing 250 by 43, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 22329.3255
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.

The quotient of the division is 22329.3255, and the remainder is 0.00035.
