We look at the division of 677405 by 43 
The aim is to understand the frequency of 43 in 677405.

On to step 1:
If we divide 6 by 43, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 43

Going ahead to step 2:
If we divide 67 by 43, we get 1 and a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 43 away from 67, we end up with 24.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 43

Advancing to step 3:
The number 43 fits into 247 5 times, leaving a remainder of 32.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 215 from 247 leaves us with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 43

Advancing to step 4:
43 goes into 324 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 157.0
Deduct 301 from 324 and we're left with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 43

Advancing to step 5:
When dividing 230 by 43, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1575.0
If we take 215 away from 230, we end up with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 43

Going ahead to step 6:
The number 43 fits into 155 3 times, leaving a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 15753.0
If we subtract 129 from 155, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
43 goes into 260 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 15753.6
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 43, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 15753.6
If we take 0 away from 20, we end up with 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 9:
43 goes into 200 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 15753.604
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
When dividing 280 by 43, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 15753.6046
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
If we divide 220 by 43, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 15753.60465
If we subtract 215 from 220, we 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.

Let's proceed to step 12:
If we divide 50 by 43, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 15753.604651
If we take 43 away from 50, we end up 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.

Moving on to step 13:
43 can be fit into 70 1 times, resulting in a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 15753.6046511
The remainder is 27 after subtracting 43 from 70.
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 result is 15753.6046511 with a remainder of 2.7e-07.
