Let's divide 52104977 by 231
The aim is to understand the frequency of 231 in 52104977.

Step 1:
231 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 231

Let's proceed to step 2:
231 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 231

Moving on to step 3:
521 divided by 231 is 2 with a remainder of 59.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 462 from 521 to get 59.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 231

Step 4:
590 divided by 231 is 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 128 after subtracting 462 from 590.
Include the next digit (4) from the dividend after 128, then repeat: 1284 / 231

Going ahead to step 5:
231 can be fit into 1284 5 times, resulting in a remainder of 129.
Put 5 as the next digit of the answer. 
Result so far: 225.0
If we take 1155 away from 1284, we end up with 129.
Take the next digit (9) from the dividend and append it to 129, then repeat: 1299 / 231

Let's proceed to step 6:
If we divide 1299 by 231, we get 5 and a remainder of 144.
Use 5 as the next digit of our solution. 
Result so far: 2255.0
If we take 1155 away from 1299, we end up with 144.
Bring next digit (7) of the dividend behind the 144 and repeat the process: 1447 / 231

Moving on to step 7:
When dividing 1447 by 231, we get 6 with a remainder of 61.
Record the quotient 6 as the next digit in the result. 
Result so far: 22556.0
Deduct 1386 from 1447 and we're left with 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 231

On to step 8:
The number 231 fits into 617 2 times, leaving a remainder of 155.
Write down 2 as next digit of the result. 
Result so far: 225562.0
Deduct 462 from 617 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
1550 divided by 231 is 6 with a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 225562.6
If we subtract 1386 from 1550, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 10:
231 goes into 1640 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 225562.67
Deduct 1617 from 1640 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
When dividing 230 by 231, we get 0 with a remainder of 230.
The next digit of our result is 0. 
Result so far: 225562.67
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 12:
231 goes into 2300 9 times with a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 225562.6709
Subtract 2079 from 2300 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 13:
The number 231 fits into 2210 9 times, leaving a remainder of 131.
The number 9 becomes the next digit in our result. 
Result so far: 225562.67099
Deduct 2079 from 2210 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

The final result is 225562.67099 with a remainder of 0.000131.
