1775441 divided by 231 
The aim is to understand the frequency of 231 in 1775441.

On to step 1:
If we divide 1 by 231, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 231

Advancing to step 2:
The number 231 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 231

Let's proceed to step 3:
When dividing 177 by 231, we get 0 with a remainder of 177.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 177 after subtracting 0 from 177.
Bring next digit (5) of the dividend behind the 177 and repeat the process: 1775 / 231

Advancing to step 4:
If we divide 1775 by 231, we get 7 and a remainder of 158.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 1617 from 1775, we get 158.
Grab the next digit (4) from the dividend, add it to 158, then carry on: 1584 / 231

Let's proceed to step 5:
1584 divided by 231 is 6 with a remainder of 198.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 1386 away from 1584, we end up with 198.
Grab the next digit (4) from the dividend, add it to 198, then carry on: 1984 / 231

Going ahead to step 6:
231 can be fit into 1984 8 times, resulting in a remainder of 136.
The next digit of our result is 8. 
Result so far: 768.0
Deduct 1848 from 1984 and we're left with 136.
Append the next digit (1) from the dividend to 136 and continue with: 1361 / 231

Step 7:
231 can be fit into 1361 5 times, resulting in a remainder of 206.
Use 5 as the next digit of our solution. 
Result so far: 7685.0
If we take 1155 away from 1361, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 8:
When dividing 2060 by 231, we get 8 with a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 7685.8
Subtracting 1848 from 2060 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 9:
The number 231 fits into 2120 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 7685.89
The remainder is 41 after subtracting 2079 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
The number 231 fits into 410 1 times, leaving a remainder of 179.
Put 1 as the next digit of the answer. 
Result so far: 7685.891
Subtracting 231 from 410 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 11:
1790 divided by 231 is 7 with a remainder of 173.
The number 7 becomes the next digit in our result. 
Result so far: 7685.8917
If we take 1617 away from 1790, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 12:
When dividing 1730 by 231, we get 7 with a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 7685.89177
If we subtract 1617 from 1730, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

In conclusion, the division gives 7685.89177 with a balance of 0.000113.
