Let's divide 438393 by 43
The aim is to understand the frequency of 43 in 438393.

Advancing to step 1:
If we divide 4 by 43, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 43

Step 2:
43 divided by 43 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 43 from 43.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 43

Advancing to step 3:
When dividing 8 by 43, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 43

On to step 4:
43 can be fit into 83 1 times, resulting in a remainder of 40.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 43 from 83 and we're left with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 43

Let's proceed to step 5:
When dividing 409 by 43, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1019.0
Subtracting 387 from 409 leaves us with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 43

Let's proceed to step 6:
43 can be fit into 223 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 10195.0
If we take 215 away from 223, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
80 divided by 43 is 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 10195.1
The remainder is 37 after subtracting 43 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
When dividing 370 by 43, we get 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 10195.18
Subtracting 344 from 370 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
43 can be fit into 260 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 10195.186
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
43 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10195.186
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 43, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 10195.18604
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
43 goes into 280 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 10195.186046
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
220 divided by 43 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 10195.1860465
Subtracting 215 from 220 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
If we divide 50 by 43, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 10195.18604651
If we subtract 43 from 50, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 10195.18604651, with a leftover of 7e-09.
