We look at the division of 80865374 by 320 
The aim is to understand the frequency of 320 in 80865374.

Moving on to step 1:
320 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 320

On to step 2:
The number 320 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 320

Step 3:
320 goes into 808 2 times with a remainder of 168.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 640 from 808, we get 168.
Include the next digit (6) from the dividend after 168, then repeat: 1686 / 320

Let's proceed to step 4:
320 goes into 1686 5 times with a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 1600 from 1686, we get 86.
Fetch the next digit (5) from the dividend, attach it to 86 and continue: 865 / 320

Going ahead to step 5:
If we divide 865 by 320, we get 2 and a remainder of 225.
The next digit of our result is 2. 
Result so far: 252.0
Deduct 640 from 865 and we're left with 225.
Append the next digit (3) from the dividend to 225 and continue with: 2253 / 320

Moving on to step 6:
If we divide 2253 by 320, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 2527.0
If we subtract 2240 from 2253, we get 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 320

Advancing to step 7:
The number 320 fits into 137 0 times, leaving a remainder of 137.
Record the quotient 0 as the next digit in the result. 
Result so far: 25270.0
If we take 0 away from 137, we end up with 137.
Fetch the next digit (4) from the dividend, attach it to 137 and continue: 1374 / 320

Step 8:
320 can be fit into 1374 4 times, resulting in a remainder of 94.
Write down 4 as next digit of the result. 
Result so far: 252704.0
Subtracting 1280 from 1374 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 9:
320 goes into 940 2 times with a remainder of 300.
Use 2 as the next digit of our solution. 
Result so far: 252704.2
If we subtract 640 from 940, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 10:
When dividing 3000 by 320, we get 9 with a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 252704.29
Subtracting 2880 from 3000 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
When dividing 1200 by 320, we get 3 with a remainder of 240.
Put 3 as the next digit of the answer. 
Result so far: 252704.293
Subtracting 960 from 1200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
2400 divided by 320 is 7 with a remainder of 160.
The next digit of our result is 7. 
Result so far: 252704.2937
Deduct 2240 from 2400 and we're left 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.

On to step 13:
When dividing 1600 by 320, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 252704.29375
The remainder is 0 after subtracting 1600 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
320 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 252704.29375
If we take 0 away from 0, we end up 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.

Let's proceed to step 15:
320 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 252704.29375
If we subtract 0 from 0, 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.

The quotient of the division is 252704.29375, and the remainder is 0.0.
