We're dividing 214978 by 43 
The aim is to understand the frequency of 43 in 214978.

Going ahead to step 1:
When dividing 2 by 43, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 43

Going ahead to step 2:
21 divided by 43 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 43

On to step 3:
43 can be fit into 214 4 times, resulting in a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 172 from 214, we get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 43

Let's proceed to step 4:
429 divided by 43 is 9 with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 387 from 429, we get 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 43

On to step 5:
427 divided by 43 is 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 499.0
If we subtract 387 from 427, we get 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 43

Moving on to step 6:
408 divided by 43 is 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 4999.0
The remainder is 21 after subtracting 387 from 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
43 can be fit into 210 4 times, resulting in a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 4999.4
If we take 172 away from 210, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
The number 43 fits into 380 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 4999.48
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 4999.488
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 4999.488 and a remainder of 0.0016.
