We divide 43518392 by 431
The aim is to understand the frequency of 431 in 43518392.

Moving on to step 1:
If we divide 4 by 431, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 431

Going ahead to step 2:
The number 431 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 431

Going ahead to step 3:
431 can be fit into 435 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 431 from 435 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 431

On to step 4:
41 divided by 431 is 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 41 leaves us with 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 431

Advancing to step 5:
431 can be fit into 418 0 times, resulting in a remainder of 418.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we take 0 away from 418, we end up with 418.
Bring next digit (3) of the dividend behind the 418 and repeat the process: 4183 / 431

Moving on to step 6:
When dividing 4183 by 431, we get 9 with a remainder of 304.
Write down 9 as next digit of the result. 
Result so far: 1009.0
Deduct 3879 from 4183 and we're left with 304.
Take the next digit (9) from the dividend and append it to 304, then repeat: 3049 / 431

Advancing to step 7:
3049 divided by 431 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 10097.0
Subtracting 3017 from 3049 leaves us with 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 431

Let's proceed to step 8:
431 can be fit into 322 0 times, resulting in a remainder of 322.
Record the quotient 0 as the next digit in the result. 
Result so far: 100970.0
Subtracting 0 from 322 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 9:
When dividing 3220 by 431, we get 7 with a remainder of 203.
Write down 7 as next digit of the result. 
Result so far: 100970.7
Deduct 3017 from 3220 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 10:
2030 divided by 431 is 4 with a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 100970.74
If we take 1724 away from 2030, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 11:
431 can be fit into 3060 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 100970.747
If we subtract 3017 from 3060, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 12:
If we divide 430 by 431, we get 0 and a remainder of 430.
Write down 0 as next digit of the result. 
Result so far: 100970.747
Subtracting 0 from 430 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 13:
4300 divided by 431 is 9 with a remainder of 421.
The next digit of our result is 9. 
Result so far: 100970.74709
Deduct 3879 from 4300 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Moving on to step 14:
4210 divided by 431 is 9 with a remainder of 331.
Put 9 as the next digit of the answer. 
Result so far: 100970.747099
If we take 3879 away from 4210, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The final outcome is 100970.747099, with a leftover of 3.31e-05.
