12118448 ÷ 430 
The aim is to understand the frequency of 430 in 12118448.

Let's proceed to step 1:
430 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 430

Step 2:
430 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 430

Step 3:
When dividing 121 by 430, we get 0 with a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Include the next digit (1) from the dividend after 121, then repeat: 1211 / 430

On to step 4:
The number 430 fits into 1211 2 times, leaving a remainder of 351.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 351 after subtracting 860 from 1211.
Grab the next digit (8) from the dividend, add it to 351, then carry on: 3518 / 430

Going ahead to step 5:
The number 430 fits into 3518 8 times, leaving a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 3440 from 3518, we get 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 430

Advancing to step 6:
430 can be fit into 784 1 times, resulting in a remainder of 354.
Use 1 as the next digit of our solution. 
Result so far: 281.0
If we subtract 430 from 784, we get 354.
Take the next digit (4) from the dividend and append it to 354, then repeat: 3544 / 430

On to step 7:
If we divide 3544 by 430, we get 8 and a remainder of 104.
The next digit of our result is 8. 
Result so far: 2818.0
If we subtract 3440 from 3544, we get 104.
Take the next digit (8) from the dividend and append it to 104, then repeat: 1048 / 430

Step 8:
1048 divided by 430 is 2 with a remainder of 188.
Put 2 as the next digit of the answer. 
Result so far: 28182.0
If we take 860 away from 1048, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 9:
If we divide 1880 by 430, we get 4 and a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 28182.4
The remainder is 160 after subtracting 1720 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
The number 430 fits into 1600 3 times, leaving a remainder of 310.
Record the quotient 3 as the next digit in the result. 
Result so far: 28182.43
The remainder is 310 after subtracting 1290 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 11:
If we divide 3100 by 430, we get 7 and a remainder of 90.
Write down 7 as next digit of the result. 
Result so far: 28182.437
The remainder is 90 after subtracting 3010 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
430 can be fit into 900 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 28182.4372
If we subtract 860 from 900, 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.

Step 13:
430 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 28182.4372
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 14:
430 can be fit into 4000 9 times, resulting in a remainder of 130.
The number 9 becomes the next digit in our result. 
Result so far: 28182.437209
If we take 3870 away from 4000, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 15:
If we divide 1300 by 430, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 28182.4372093
If we subtract 1290 from 1300, 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.

Step 16:
The number 430 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 28182.4372093
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 28182.4372093 and a remainder of 1e-07.
