We look at the division of 790902 by 43 
The aim is to understand the frequency of 43 in 790902.

Step 1:
If we divide 7 by 43, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 43

Going ahead to step 2:
When dividing 79 by 43, we get 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 43 away from 79, we end up with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 43

Step 3:
43 can be fit into 360 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 16 after subtracting 344 from 360.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 43

Moving on to step 4:
When dividing 169 by 43, we get 3 with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
Deduct 129 from 169 and we're left with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 43

Going ahead to step 5:
400 divided by 43 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 1839.0
If we subtract 387 from 400, we get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 43

Step 6:
The number 43 fits into 132 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 18393.0
The remainder is 3 after subtracting 129 from 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 43, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 18393.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
The number 43 fits into 300 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 18393.06
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
420 divided by 43 is 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 18393.069
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
43 goes into 330 7 times with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 18393.0697
If we take 301 away from 330, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
43 can be fit into 290 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 18393.06976
Deduct 258 from 290 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
If we divide 320 by 43, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 18393.069767
The remainder is 19 after subtracting 301 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 18393.0697674
Deduct 172 from 190 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
43 can be fit into 180 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 18393.06976744
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 18393.06976744 with a remaining 8e-09.
