We look at the division of 14997202 by 231 
The aim is to understand the frequency of 231 in 14997202.

Let's proceed to step 1:
If we divide 1 by 231, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 231

Step 2:
If we divide 14 by 231, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 231

Moving on to step 3:
231 can be fit into 149 0 times, resulting in a remainder of 149.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 149 leaves us with 149.
Grab the next digit (9) from the dividend, add it to 149, then carry on: 1499 / 231

Advancing to step 4:
231 goes into 1499 6 times with a remainder of 113.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 1386 from 1499, we get 113.
Fetch the next digit (7) from the dividend, attach it to 113 and continue: 1137 / 231

Let's proceed to step 5:
231 can be fit into 1137 4 times, resulting in a remainder of 213.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 924 from 1137 to get 213.
Take the next digit (2) from the dividend and append it to 213, then repeat: 2132 / 231

Step 6:
2132 divided by 231 is 9 with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 649.0
If we take 2079 away from 2132, we end up with 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 231

Going ahead to step 7:
The number 231 fits into 530 2 times, leaving a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 6492.0
If we subtract 462 from 530, we get 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 231

Advancing to step 8:
If we divide 682 by 231, we get 2 and a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 64922.0
If we subtract 462 from 682, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 9:
2200 divided by 231 is 9 with a remainder of 121.
Write down 9 as next digit of the result. 
Result so far: 64922.9
If we subtract 2079 from 2200, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 10:
231 can be fit into 1210 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 64922.95
Deduct 1155 from 1210 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
The number 231 fits into 550 2 times, leaving a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 64922.952
Deduct 462 from 550 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 12:
When dividing 880 by 231, we get 3 with a remainder of 187.
Write down 3 as next digit of the result. 
Result so far: 64922.9523
The remainder is 187 after subtracting 693 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 13:
231 can be fit into 1870 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 64922.95238
If we take 1848 away from 1870, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
231 goes into 220 0 times with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 64922.95238
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 15:
When dividing 2200 by 231, we get 9 with a remainder of 121.
Write down 9 as next digit of the result. 
Result so far: 64922.9523809
Deduct 2079 from 2200 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 16:
231 can be fit into 1210 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 64922.95238095
If we subtract 1155 from 1210, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 64922.95238095 with a remainder of 5.5e-08.
