We look at the division of 777270 by 43 
The aim is to understand the frequency of 43 in 777270.

Going ahead to step 1:
If we divide 7 by 43, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 43

Step 2:
When dividing 77 by 43, we get 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 43 from 77 leaves us with 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 43

Step 3:
If we divide 347 by 43, we get 8 and a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 344 from 347, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 43

Step 4:
When dividing 32 by 43, we get 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 180.0
The remainder is 32 after subtracting 0 from 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 43

Advancing to step 5:
The number 43 fits into 327 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 1807.0
If we subtract 301 from 327, we get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 43

Going ahead to step 6:
43 can be fit into 260 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 18076.0
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 43, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 18076.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
43 can be fit into 200 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 18076.04
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
When dividing 280 by 43, we get 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 18076.046
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
The number 43 fits into 220 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 18076.0465
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
50 divided by 43 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 18076.04651
Subtracting 43 from 50 leaves us 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.

Going ahead to step 12:
43 can be fit into 70 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 18076.046511
If we take 43 away from 70, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 18076.046511, with a leftover of 2.7e-06.
