We look at the division of 23240163 by 431 
The aim is to understand the frequency of 431 in 23240163.

Moving on to step 1:
If we divide 2 by 431, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 431

On to step 2:
When dividing 23 by 431, we get 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 431

Moving on to step 3:
431 goes into 232 0 times with a remainder of 232.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 232, we get 232.
Include the next digit (4) from the dividend after 232, then repeat: 2324 / 431

Step 4:
The number 431 fits into 2324 5 times, leaving a remainder of 169.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 2155 from 2324 to get 169.
Bring next digit (0) of the dividend behind the 169 and repeat the process: 1690 / 431

Advancing to step 5:
431 goes into 1690 3 times with a remainder of 397.
Put 3 as the next digit of the answer. 
Result so far: 53.0
If we take 1293 away from 1690, we end up with 397.
Include the next digit (1) from the dividend after 397, then repeat: 3971 / 431

Going ahead to step 6:
3971 divided by 431 is 9 with a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 539.0
Subtracting 3879 from 3971 leaves us with 92.
Append the next digit (6) from the dividend to 92 and continue with: 926 / 431

Step 7:
If we divide 926 by 431, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 5392.0
If we subtract 862 from 926, we get 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 431

Going ahead to step 8:
If we divide 643 by 431, we get 1 and a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 53921.0
If we take 431 away from 643, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 9:
2120 divided by 431 is 4 with a remainder of 396.
Write down 4 as next digit of the result. 
Result so far: 53921.4
Subtracting 1724 from 2120 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 10:
3960 divided by 431 is 9 with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 53921.49
The remainder is 81 after subtracting 3879 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 11:
431 can be fit into 810 1 times, resulting in a remainder of 379.
The number 1 becomes the next digit in our result. 
Result so far: 53921.491
If we take 431 away from 810, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 12:
431 goes into 3790 8 times with a remainder of 342.
Write down 8 as next digit of the result. 
Result so far: 53921.4918
Subtracting 3448 from 3790 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 13:
When dividing 3420 by 431, we get 7 with a remainder of 403.
Use 7 as the next digit of our solution. 
Result so far: 53921.49187
Deduct 3017 from 3420 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Advancing to step 14:
431 goes into 4030 9 times with a remainder of 151.
The next digit of our result is 9. 
Result so far: 53921.491879
The remainder is 151 after subtracting 3879 from 4030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 15:
If we divide 1510 by 431, we get 3 and a remainder of 217.
Put 3 as the next digit of the answer. 
Result so far: 53921.4918793
Subtracting 1293 from 1510 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 16:
431 goes into 2170 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 53921.49187935
Subtract 2155 from 2170 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 53921.49187935, with a leftover of 1.5e-08.
