We're dividing 45318594 by 43 
The aim is to understand the frequency of 43 in 45318594.

Step 1:
43 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 43

Step 2:
45 divided by 43 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 43 from 45 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 43

Going ahead to step 3:
23 divided by 43 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 23, we end up with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 43

Going ahead to step 4:
If we divide 231 by 43, we get 5 and a remainder of 16.
The next digit of our result is 5. 
Result so far: 105.0
Subtracting 215 from 231 leaves us with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 43

Let's proceed to step 5:
The number 43 fits into 168 3 times, leaving a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 1053.0
Subtract 129 from 168 to get 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 43

Moving on to step 6:
When dividing 395 by 43, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 10539.0
The remainder is 8 after subtracting 387 from 395.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 43

Let's proceed to step 7:
43 can be fit into 89 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 105392.0
The remainder is 3 after subtracting 86 from 89.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 43

On to step 8:
When dividing 34 by 43, we get 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 1053920.0
Deduct 0 from 34 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
When dividing 340 by 43, we get 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 1053920.7
Subtract 301 from 340 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 10:
When dividing 390 by 43, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 1053920.79
The remainder is 3 after subtracting 387 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
43 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 1053920.79
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead 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: 1053920.7906
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
The number 43 fits into 420 9 times, leaving a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 1053920.79069
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
43 goes into 330 7 times with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 1053920.790697
If we take 301 away from 330, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 15:
The number 43 fits into 290 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 1053920.7906976
Subtract 258 from 290 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
320 divided by 43 is 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 1053920.79069767
If we subtract 301 from 320, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 1053920.79069767 with a balance of 1.9e-08.
