We divide 4999559 by 320
The aim is to understand the frequency of 320 in 4999559.

Moving on to step 1:
The number 320 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 320

On to step 2:
When dividing 49 by 320, we get 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 320

Advancing to step 3:
499 divided by 320 is 1 with a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 320 from 499 to get 179.
Include the next digit (9) from the dividend after 179, then repeat: 1799 / 320

Going ahead to step 4:
The number 320 fits into 1799 5 times, leaving a remainder of 199.
The next digit of our result is 5. 
Result so far: 15.0
If we take 1600 away from 1799, we end up with 199.
Bring next digit (5) of the dividend behind the 199 and repeat the process: 1995 / 320

Going ahead to step 5:
If we divide 1995 by 320, we get 6 and a remainder of 75.
The next digit of our result is 6. 
Result so far: 156.0
If we subtract 1920 from 1995, we get 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 320

Advancing to step 6:
When dividing 755 by 320, we get 2 with a remainder of 115.
Use 2 as the next digit of our solution. 
Result so far: 1562.0
The remainder is 115 after subtracting 640 from 755.
Bring next digit (9) of the dividend behind the 115 and repeat the process: 1159 / 320

On to step 7:
The number 320 fits into 1159 3 times, leaving a remainder of 199.
Put 3 as the next digit of the answer. 
Result so far: 15623.0
Subtract 960 from 1159 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 8:
1990 divided by 320 is 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 15623.6
If we take 1920 away from 1990, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
700 divided by 320 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 15623.62
Subtracting 640 from 700 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
320 goes into 600 1 times with a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 15623.621
If we subtract 320 from 600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 11:
When dividing 2800 by 320, we get 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 15623.6218
The remainder is 240 after subtracting 2560 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
If we divide 2400 by 320, we get 7 and a remainder of 160.
Record the quotient 7 as the next digit in the result. 
Result so far: 15623.62187
Subtracting 2240 from 2400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
The number 320 fits into 1600 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15623.621875
Subtract 1600 from 1600 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 14:
If we divide 0 by 320, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15623.621875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
320 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15623.621875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 15623.621875 and a remainder of 0.0.
