We're dividing 15532733 by 231 
The aim is to understand the frequency of 231 in 15532733.

Advancing to step 1:
If we divide 1 by 231, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 231

Let's proceed to step 2:
When dividing 15 by 231, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 231

Let's proceed to step 3:
If we divide 155 by 231, we get 0 and a remainder of 155.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 155 after subtracting 0 from 155.
Bring next digit (3) of the dividend behind the 155 and repeat the process: 1553 / 231

Going ahead to step 4:
231 goes into 1553 6 times with a remainder of 167.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 1386 from 1553 to get 167.
Grab the next digit (2) from the dividend, add it to 167, then carry on: 1672 / 231

Step 5:
1672 divided by 231 is 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtracting 1617 from 1672 leaves us with 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 231

Let's proceed to step 6:
557 divided by 231 is 2 with a remainder of 95.
Put 2 as the next digit of the answer. 
Result so far: 672.0
The remainder is 95 after subtracting 462 from 557.
Fetch the next digit (3) from the dividend, attach it to 95 and continue: 953 / 231

On to step 7:
231 can be fit into 953 4 times, resulting in a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 6724.0
The remainder is 29 after subtracting 924 from 953.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 231

Moving on to step 8:
293 divided by 231 is 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 67241.0
Subtracting 231 from 293 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
620 divided by 231 is 2 with a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 67241.2
Subtracting 462 from 620 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 10:
When dividing 1580 by 231, we get 6 with a remainder of 194.
Write down 6 as next digit of the result. 
Result so far: 67241.26
If we take 1386 away from 1580, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 11:
The number 231 fits into 1940 8 times, leaving a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 67241.268
The remainder is 92 after subtracting 1848 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 12:
920 divided by 231 is 3 with a remainder of 227.
The number 3 becomes the next digit in our result. 
Result so far: 67241.2683
Subtract 693 from 920 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 13:
If we divide 2270 by 231, we get 9 and a remainder of 191.
Put 9 as the next digit of the answer. 
Result so far: 67241.26839
If we subtract 2079 from 2270, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 14:
231 goes into 1910 8 times with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 67241.268398
If we take 1848 away from 1910, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 15:
231 can be fit into 620 2 times, resulting in a remainder of 158.
Put 2 as the next digit of the answer. 
Result so far: 67241.2683982
Deduct 462 from 620 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 16:
When dividing 1580 by 231, we get 6 with a remainder of 194.
Put 6 as the next digit of the answer. 
Result so far: 67241.26839826
If we subtract 1386 from 1580, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final outcome is 67241.26839826, with a leftover of 1.94e-07.
