We look at the division of 78905321 by 923 
The aim is to understand the frequency of 923 in 78905321.

Going ahead to step 1:
If we divide 7 by 923, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 923

Advancing to step 2:
If we divide 78 by 923, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 923

Moving on to step 3:
If we divide 789 by 923, we get 0 and a remainder of 789.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 789 after subtracting 0 from 789.
Include the next digit (0) from the dividend after 789, then repeat: 7890 / 923

Step 4:
923 can be fit into 7890 8 times, resulting in a remainder of 506.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7384 from 7890 and we're left with 506.
Include the next digit (5) from the dividend after 506, then repeat: 5065 / 923

Let's proceed to step 5:
The number 923 fits into 5065 5 times, leaving a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 450 after subtracting 4615 from 5065.
Append the next digit (3) from the dividend to 450 and continue with: 4503 / 923

Going ahead to step 6:
4503 divided by 923 is 4 with a remainder of 811.
The number 4 becomes the next digit in our result. 
Result so far: 854.0
Subtracting 3692 from 4503 leaves us with 811.
Append the next digit (2) from the dividend to 811 and continue with: 8112 / 923

Step 7:
The number 923 fits into 8112 8 times, leaving a remainder of 728.
Record the quotient 8 as the next digit in the result. 
Result so far: 8548.0
If we subtract 7384 from 8112, we get 728.
Fetch the next digit (1) from the dividend, attach it to 728 and continue: 7281 / 923

Let's proceed to step 8:
If we divide 7281 by 923, we get 7 and a remainder of 820.
The number 7 becomes the next digit in our result. 
Result so far: 85487.0
The remainder is 820 after subtracting 6461 from 7281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Step 9:
When dividing 8200 by 923, we get 8 with a remainder of 816.
Record the quotient 8 as the next digit in the result. 
Result so far: 85487.8
Deduct 7384 from 8200 and we're left with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Going ahead to step 10:
When dividing 8160 by 923, we get 8 with a remainder of 776.
Use 8 as the next digit of our solution. 
Result so far: 85487.88
Subtract 7384 from 8160 to get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

In conclusion, the division gives 85487.88 with a balance of 0.776.
