Let's divide 780431 by 43
The aim is to understand the frequency of 43 in 780431.

Moving on to step 1:
The number 43 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 43

Going ahead to step 2:
The number 43 fits into 78 1 times, leaving a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 43 from 78 leaves us with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 43

On to step 3:
43 goes into 350 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 344 away from 350, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 43

Moving on to step 4:
The number 43 fits into 64 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 181.0
Subtracting 43 from 64 leaves us with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 43

On to step 5:
When dividing 213 by 43, we get 4 with a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 1814.0
Subtracting 172 from 213 leaves us with 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 43

On to step 6:
If we divide 411 by 43, we get 9 and a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 18149.0
If we subtract 387 from 411, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
When dividing 240 by 43, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 18149.5
If we take 215 away from 240, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
The number 43 fits into 250 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 18149.55
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 18149.55, with a leftover of 0.035.
