We look at the division of 18010660 by 320 
The aim is to understand the frequency of 320 in 18010660.

On to step 1:
If we divide 1 by 320, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 320

Going ahead to step 2:
320 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 320

On to step 3:
If we divide 180 by 320, we get 0 and a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 180, we get 180.
Include the next digit (1) from the dividend after 180, then repeat: 1801 / 320

Going ahead to step 4:
320 can be fit into 1801 5 times, resulting in a remainder of 201.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 1600 from 1801, we get 201.
Bring next digit (0) of the dividend behind the 201 and repeat the process: 2010 / 320

Step 5:
320 can be fit into 2010 6 times, resulting in a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Deduct 1920 from 2010 and we're left with 90.
Append the next digit (6) from the dividend to 90 and continue with: 906 / 320

Let's proceed to step 6:
906 divided by 320 is 2 with a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 562.0
Deduct 640 from 906 and we're left with 266.
Grab the next digit (6) from the dividend, add it to 266, then carry on: 2666 / 320

On to step 7:
If we divide 2666 by 320, we get 8 and a remainder of 106.
Record the quotient 8 as the next digit in the result. 
Result so far: 5628.0
Deduct 2560 from 2666 and we're left with 106.
Take the next digit (0) from the dividend and append it to 106, then repeat: 1060 / 320

Going ahead to step 8:
When dividing 1060 by 320, we get 3 with a remainder of 100.
Write down 3 as next digit of the result. 
Result so far: 56283.0
If we subtract 960 from 1060, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 9:
320 can be fit into 1000 3 times, resulting in a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 56283.3
If we subtract 960 from 1000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
400 divided by 320 is 1 with a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 56283.31
If we subtract 320 from 400, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
When dividing 800 by 320, we get 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 56283.312
Subtracting 640 from 800 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.

Going ahead to step 12:
If we divide 1600 by 320, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 56283.3125
If we subtract 1600 from 1600, we 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 13:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 56283.3125
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.

Moving on to step 14:
When dividing 0 by 320, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 56283.3125
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 56283.3125 with a balance of 0.0.
