Let's divide 57996066 by 231
The aim is to understand the frequency of 231 in 57996066.

Going ahead to step 1:
231 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 231

Step 2:
231 can be fit into 57 0 times, resulting in a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 231

Moving on to step 3:
231 goes into 579 2 times with a remainder of 117.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 117 after subtracting 462 from 579.
Take the next digit (9) from the dividend and append it to 117, then repeat: 1179 / 231

Moving on to step 4:
231 goes into 1179 5 times with a remainder of 24.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 1155 from 1179 and we're left with 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 231

Going ahead to step 5:
246 divided by 231 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 251.0
If we take 231 away from 246, we end up with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 231

Going ahead to step 6:
231 goes into 150 0 times with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 2510.0
Subtract 0 from 150 to get 150.
Include the next digit (6) from the dividend after 150, then repeat: 1506 / 231

On to step 7:
1506 divided by 231 is 6 with a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 25106.0
Subtract 1386 from 1506 to get 120.
Bring next digit (6) of the dividend behind the 120 and repeat the process: 1206 / 231

Step 8:
231 can be fit into 1206 5 times, resulting in a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 251065.0
If we subtract 1155 from 1206, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
When dividing 510 by 231, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 251065.2
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
231 goes into 480 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 251065.22
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 251065.22 with a balance of 0.018.
