71284402 divided by 320 
The aim is to understand the frequency of 320 in 71284402.

Advancing to step 1:
7 divided by 320 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 320

Going ahead to step 2:
320 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 320

Step 3:
The number 320 fits into 712 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 640 from 712 leaves us with 72.
Grab the next digit (8) from the dividend, add it to 72, then carry on: 728 / 320

On to step 4:
728 divided by 320 is 2 with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 640 away from 728, we end up with 88.
Fetch the next digit (4) from the dividend, attach it to 88 and continue: 884 / 320

Step 5:
320 can be fit into 884 2 times, resulting in a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 222.0
The remainder is 244 after subtracting 640 from 884.
Include the next digit (4) from the dividend after 244, then repeat: 2444 / 320

On to step 6:
320 goes into 2444 7 times with a remainder of 204.
Put 7 as the next digit of the answer. 
Result so far: 2227.0
Deduct 2240 from 2444 and we're left with 204.
Bring next digit (0) of the dividend behind the 204 and repeat the process: 2040 / 320

On to step 7:
The number 320 fits into 2040 6 times, leaving a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 22276.0
Subtract 1920 from 2040 to get 120.
Grab the next digit (2) from the dividend, add it to 120, then carry on: 1202 / 320

Step 8:
If we divide 1202 by 320, we get 3 and a remainder of 242.
The next digit of our result is 3. 
Result so far: 222763.0
The remainder is 242 after subtracting 960 from 1202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 9:
320 goes into 2420 7 times with a remainder of 180.
Write down 7 as next digit of the result. 
Result so far: 222763.7
Deduct 2240 from 2420 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
The number 320 fits into 1800 5 times, leaving a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 222763.75
Subtract 1600 from 1800 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
2000 divided by 320 is 6 with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 222763.756
The remainder is 80 after subtracting 1920 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
800 divided by 320 is 2 with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 222763.7562
If we subtract 640 from 800, we get 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:
When dividing 1600 by 320, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 222763.75625
Subtracting 1600 from 1600 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.

Going ahead to step 14:
0 divided by 320 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 222763.75625
Subtract 0 from 0 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.

Going ahead to step 15:
The number 320 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 222763.75625
Subtract 0 from 0 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.

After the division, we end up with 222763.75625 and a remainder of 0.0.
