We look at the division of 90244780 by 731 
The aim is to understand the frequency of 731 in 90244780.

Advancing to step 1:
When dividing 9 by 731, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 731

Going ahead to step 2:
731 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (2) from the dividend after 90, then repeat: 902 / 731

Going ahead to step 3:
When dividing 902 by 731, we get 1 with a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 731 from 902, we get 171.
Bring next digit (4) of the dividend behind the 171 and repeat the process: 1714 / 731

On to step 4:
If we divide 1714 by 731, we get 2 and a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 1462 from 1714 leaves us with 252.
Grab the next digit (4) from the dividend, add it to 252, then carry on: 2524 / 731

Moving on to step 5:
2524 divided by 731 is 3 with a remainder of 331.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we take 2193 away from 2524, we end up with 331.
Bring next digit (7) of the dividend behind the 331 and repeat the process: 3317 / 731

Going ahead to step 6:
3317 divided by 731 is 4 with a remainder of 393.
The number 4 becomes the next digit in our result. 
Result so far: 1234.0
Subtracting 2924 from 3317 leaves us with 393.
Take the next digit (8) from the dividend and append it to 393, then repeat: 3938 / 731

Step 7:
3938 divided by 731 is 5 with a remainder of 283.
The number 5 becomes the next digit in our result. 
Result so far: 12345.0
Subtract 3655 from 3938 to get 283.
Append the next digit (0) from the dividend to 283 and continue with: 2830 / 731

Let's proceed to step 8:
If we divide 2830 by 731, we get 3 and a remainder of 637.
Put 3 as the next digit of the answer. 
Result so far: 123453.0
The remainder is 637 after subtracting 2193 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Step 9:
The number 731 fits into 6370 8 times, leaving a remainder of 522.
Write down 8 as next digit of the result. 
Result so far: 123453.8
Subtracting 5848 from 6370 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 10:
5220 divided by 731 is 7 with a remainder of 103.
Use 7 as the next digit of our solution. 
Result so far: 123453.87
Subtracting 5117 from 5220 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 11:
When dividing 1030 by 731, we get 1 with a remainder of 299.
Write down 1 as next digit of the result. 
Result so far: 123453.871
If we take 731 away from 1030, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 12:
If we divide 2990 by 731, we get 4 and a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 123453.8714
Subtract 2924 from 2990 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
731 can be fit into 660 0 times, resulting in a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 123453.8714
If we take 0 away from 660, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 14:
When dividing 6600 by 731, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 123453.871409
If we subtract 6579 from 6600, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 15:
731 can be fit into 210 0 times, resulting in a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 123453.871409
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 16:
2100 divided by 731 is 2 with a remainder of 638.
The number 2 becomes the next digit in our result. 
Result so far: 123453.87140902
The remainder is 638 after subtracting 1462 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

In conclusion, the division gives 123453.87140902 with a balance of 6.38e-07.
