We're dividing 107621 by 43 
The aim is to understand the frequency of 43 in 107621.

Going ahead to step 1:
If we divide 1 by 43, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 43

Advancing to step 2:
43 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 43

Advancing to step 3:
43 can be fit into 107 2 times, resulting in a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 86 from 107 leaves us with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 43

Moving on to step 4:
If we divide 216 by 43, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 215 from 216, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 43

Moving on to step 5:
If we divide 12 by 43, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 43

On to step 6:
121 divided by 43 is 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 2502.0
Deduct 86 from 121 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.

Advancing to step 7:
43 goes into 350 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 2502.8
The remainder is 6 after subtracting 344 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 43 fits into 60 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 2502.81
If we take 43 away from 60, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
The number 43 fits into 170 3 times, leaving a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 2502.813
The remainder is 41 after subtracting 129 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
410 divided by 43 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 2502.8139
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
If we divide 230 by 43, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 2502.81395
Subtract 215 from 230 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
If we divide 150 by 43, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 2502.813953
If we subtract 129 from 150, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
210 divided by 43 is 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 2502.8139534
If we take 172 away from 210, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
380 divided by 43 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 2502.81395348
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 2502.81395348, and the remainder is 3.6e-08.
