We look at the division of 783895 by 43 
The aim is to understand the frequency of 43 in 783895.

Moving on to step 1:
The number 43 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 43

Going ahead to step 2:
43 goes into 78 1 times with a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
If we take 43 away from 78, we end up with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 43

Going ahead to step 3:
43 goes into 353 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 344 from 353 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 43

On to step 4:
If we divide 98 by 43, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 182.0
If we take 86 away from 98, we end up with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 43

Going ahead to step 5:
If we divide 129 by 43, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 1823.0
Deduct 129 from 129 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 43

Moving on to step 6:
When dividing 5 by 43, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 18230.0
If we subtract 0 from 5, 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.

Advancing to step 7:
When dividing 50 by 43, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 18230.1
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
When dividing 70 by 43, we get 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 18230.11
If we subtract 43 from 70, we get 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 quotient of the division is 18230.11, and the remainder is 0.027.
