We look at the division of 748313 by 43 
The aim is to understand the frequency of 43 in 748313.

Advancing to step 1:
The number 43 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 43

Let's proceed to step 2:
74 divided by 43 is 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
If we take 43 away from 74, we end up with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 43

Advancing to step 3:
43 goes into 318 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 301 from 318 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 43

On to step 4:
43 goes into 173 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 174.0
Subtract 172 from 173 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 43

Step 5:
The number 43 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 1740.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 43

Moving on to step 6:
When dividing 113 by 43, we get 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 17402.0
Subtract 86 from 113 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 43 fits into 270 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 17402.6
Subtracting 258 from 270 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
43 can be fit into 120 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 17402.62
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
43 goes into 340 7 times with a remainder of 39.
The next digit of our result is 7. 
Result so far: 17402.627
Subtracting 301 from 340 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 10:
43 goes into 390 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 17402.6279
Deduct 387 from 390 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
43 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 17402.6279
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 43, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 17402.627906
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
When dividing 420 by 43, we get 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 17402.6279069
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 14:
330 divided by 43 is 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 17402.62790697
Subtract 301 from 330 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 17402.62790697, and the remainder is 2.9e-08.
