78 divided by 43 
The aim is to understand the frequency of 43 in 78.

Going ahead to step 1:
43 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 43

Advancing to step 2:
78 divided by 43 is 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 43 from 78 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 3:
If we divide 350 by 43, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 1.8
Subtract 344 from 350 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 4:
The number 43 fits into 60 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.81
The remainder is 17 after subtracting 43 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 5:
If we divide 170 by 43, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 1.813
Subtracting 129 from 170 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 6:
If we divide 410 by 43, we get 9 and a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 1.8139
If we subtract 387 from 410, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
43 can be fit into 230 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1.81395
Subtract 215 from 230 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
43 goes into 150 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 1.813953
If we subtract 129 from 150, we get 21.
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 9:
43 can be fit into 210 4 times, resulting in a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 1.8139534
Deduct 172 from 210 and we're left 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.

Advancing to step 10:
43 can be fit into 380 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 1.81395348
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 1.81395348 and a remainder of 3.6e-08.
