We're dividing 778710 by 43 
The aim is to understand the frequency of 43 in 778710.

Going ahead to step 1:
7 divided by 43 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 43

On to step 2:
If we divide 77 by 43, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 43 from 77 and we're left with 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 43

On to step 3:
When dividing 348 by 43, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 344 from 348, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 43

Moving on to step 4:
When dividing 47 by 43, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 181.0
If we subtract 43 from 47, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 43

Let's proceed to step 5:
43 goes into 41 0 times with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 1810.0
Subtracting 0 from 41 leaves us with 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 43

Let's proceed to step 6:
43 can be fit into 410 9 times, resulting in a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 18109.0
Deduct 387 from 410 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
When dividing 230 by 43, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 18109.5
If we take 215 away from 230, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
The number 43 fits into 150 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 18109.53
Subtract 129 from 150 to 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.

Let's proceed to step 9:
210 divided by 43 is 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 18109.534
Subtracting 172 from 210 leaves us 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:
The number 43 fits into 380 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 18109.5348
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
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: 18109.53488
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 18109.53488 and a remainder of 1.6e-05.
