Let's divide 738456 by 43
The aim is to understand the frequency of 43 in 738456.

Step 1:
The number 43 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 43

Step 2:
If we divide 73 by 43, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 43 away from 73, we end up with 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 43

Let's proceed to step 3:
If we divide 308 by 43, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 7 after subtracting 301 from 308.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 43

On to step 4:
74 divided by 43 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
If we take 43 away from 74, we end up with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 43

Going ahead to step 5:
43 goes into 315 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 1717.0
Subtract 301 from 315 to get 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 43

Advancing to step 6:
When dividing 146 by 43, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 17173.0
Subtracting 129 from 146 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
170 divided by 43 is 3 with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 17173.3
If we subtract 129 from 170, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 8:
The number 43 fits into 410 9 times, leaving a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 17173.39
If we take 387 away from 410, we end up 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 9:
230 divided by 43 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 17173.395
Deduct 215 from 230 and we're left 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 10:
150 divided by 43 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 17173.3953
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.

Going ahead to step 11:
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: 17173.39534
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.

Going ahead to step 12:
When dividing 380 by 43, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 17173.395348
Subtracting 344 from 380 leaves us 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.

Let's proceed to step 13:
43 can be fit into 360 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 17173.3953488
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 17173.3953488 with a remaining 1.6e-07.
