48381223 divided by 43 
The aim is to understand the frequency of 43 in 48381223.

Step 1:
The number 43 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 43

Moving on to step 2:
48 divided by 43 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 43 from 48, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 43

On to step 3:
43 can be fit into 53 1 times, resulting in a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 10 after subtracting 43 from 53.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 43

Step 4:
43 can be fit into 108 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Deduct 86 from 108 and we're left with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 43

Step 5:
221 divided by 43 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 1125.0
The remainder is 6 after subtracting 215 from 221.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 43

Let's proceed to step 6:
When dividing 62 by 43, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11251.0
If we subtract 43 from 62, we get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 43

Moving on to step 7:
192 divided by 43 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 112514.0
Deduct 172 from 192 and we're left with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 43

Let's proceed to step 8:
43 can be fit into 203 4 times, resulting in a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 1125144.0
The remainder is 31 after subtracting 172 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
310 divided by 43 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 1125144.7
Subtract 301 from 310 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
43 can be fit into 90 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 1125144.72
The remainder is 4 after subtracting 86 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
When dividing 40 by 43, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1125144.72
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
400 divided by 43 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 1125144.7209
Subtracting 387 from 400 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
If we divide 130 by 43, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1125144.72093
The remainder is 1 after subtracting 129 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
10 divided by 43 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1125144.72093
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
100 divided by 43 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 1125144.7209302
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 16:
43 can be fit into 140 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 1125144.72093023
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 1125144.72093023 and a remainder of 1.1e-08.
