We look at the division of 359102 by 43 
The aim is to understand the frequency of 43 in 359102.

Step 1:
When dividing 3 by 43, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 43

On to step 2:
43 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 43

Advancing to step 3:
When dividing 359 by 43, we get 8 with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 344 from 359, we get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 43

Let's proceed to step 4:
The number 43 fits into 151 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtract 129 from 151 to get 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 43

Let's proceed to step 5:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 835.0
Deduct 215 from 220 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 43

Moving on to step 6:
43 can be fit into 52 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 8351.0
If we subtract 43 from 52, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
90 divided by 43 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 8351.2
Subtract 86 from 90 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
43 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8351.2
Deduct 0 from 40 and we're left with 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 9:
If we divide 400 by 43, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 8351.209
The remainder is 13 after subtracting 387 from 400.
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 10:
43 goes into 130 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 8351.2093
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.

Advancing to step 11:
When dividing 10 by 43, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8351.2093
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
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: 8351.209302
Subtract 86 from 100 to 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.

Going ahead to step 13:
The number 43 fits into 140 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 8351.2093023
Deduct 129 from 140 and we're left 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.

Step 14:
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: 8351.20930232
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 8351.20930232, and the remainder is 2.4e-08.
