We look at the division of 73768425 by 231 
The aim is to understand the frequency of 231 in 73768425.

Going ahead to step 1:
The number 231 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 231

Step 2:
If we divide 73 by 231, we get 0 and a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 231

Let's proceed to step 3:
The number 231 fits into 737 3 times, leaving a remainder of 44.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 44 after subtracting 693 from 737.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 231

On to step 4:
If we divide 446 by 231, we get 1 and a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 215 after subtracting 231 from 446.
Append the next digit (8) from the dividend to 215 and continue with: 2158 / 231

Advancing to step 5:
2158 divided by 231 is 9 with a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 319.0
Subtracting 2079 from 2158 leaves us with 79.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 231

Step 6:
When dividing 794 by 231, we get 3 with a remainder of 101.
Write down 3 as next digit of the result. 
Result so far: 3193.0
Deduct 693 from 794 and we're left with 101.
Include the next digit (2) from the dividend after 101, then repeat: 1012 / 231

Moving on to step 7:
The number 231 fits into 1012 4 times, leaving a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 31934.0
If we take 924 away from 1012, we end up with 88.
Append the next digit (5) from the dividend to 88 and continue with: 885 / 231

Moving on to step 8:
231 can be fit into 885 3 times, resulting in a remainder of 192.
The number 3 becomes the next digit in our result. 
Result so far: 319343.0
The remainder is 192 after subtracting 693 from 885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 9:
When dividing 1920 by 231, we get 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 319343.8
Subtract 1848 from 1920 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
231 goes into 720 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 319343.83
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
231 goes into 270 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 319343.831
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 12:
231 goes into 390 1 times with a remainder of 159.
Record the quotient 1 as the next digit in the result. 
Result so far: 319343.8311
If we subtract 231 from 390, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The final outcome is 319343.8311, with a leftover of 0.00159.
