We're dividing 642014 by 43 
The aim is to understand the frequency of 43 in 642014.

Step 1:
43 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 43

On to step 2:
If we divide 64 by 43, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 43 from 64 leaves us with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 43

On to step 3:
When dividing 212 by 43, we get 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 172 from 212, we get 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 43

Moving on to step 4:
When dividing 400 by 43, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
Subtract 387 from 400 to get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 43

Advancing to step 5:
43 goes into 131 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 1493.0
The remainder is 2 after subtracting 129 from 131.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 43

Advancing to step 6:
If we divide 24 by 43, we get 0 and a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 14930.0
Subtract 0 from 24 to 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.
The next digit of our result is 5. 
Result so far: 14930.5
If we subtract 215 from 240, we get 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:
If we divide 250 by 43, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 14930.55
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.

Our division results in 14930.55 with a remaining 0.035.
