80220516 ÷ 280 
The aim is to understand the frequency of 280 in 80220516.

On to step 1:
The number 280 fits into 8 0 times, leaving 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.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 280

Let's proceed to step 2:
If we divide 80 by 280, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (2) from the dividend, attach it to 80 and continue: 802 / 280

Going ahead to step 3:
802 divided by 280 is 2 with a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 560 from 802, we get 242.
Bring next digit (2) of the dividend behind the 242 and repeat the process: 2422 / 280

Advancing to step 4:
280 goes into 2422 8 times with a remainder of 182.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 182 after subtracting 2240 from 2422.
Append the next digit (0) from the dividend to 182 and continue with: 1820 / 280

Let's proceed to step 5:
The number 280 fits into 1820 6 times, leaving a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 286.0
Subtracting 1680 from 1820 leaves us with 140.
Append the next digit (5) from the dividend to 140 and continue with: 1405 / 280

Going ahead to step 6:
If we divide 1405 by 280, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 2865.0
If we subtract 1400 from 1405, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 280

On to step 7:
The number 280 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 28650.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 280

Step 8:
280 goes into 516 1 times with a remainder of 236.
The next digit of our result is 1. 
Result so far: 286501.0
Subtracting 280 from 516 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 9:
If we divide 2360 by 280, we get 8 and a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 286501.8
Subtract 2240 from 2360 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
If we divide 1200 by 280, we get 4 and a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 286501.84
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
When dividing 800 by 280, we get 2 with a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 286501.842
If we take 560 away from 800, we end up 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.

On to step 12:
If we divide 2400 by 280, we get 8 and a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 286501.8428
If we subtract 2240 from 2400, 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:
If we divide 1600 by 280, we get 5 and a remainder of 200.
The next digit of our result is 5. 
Result so far: 286501.84285
Subtracting 1400 from 1600 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
280 can be fit into 2000 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 286501.842857
Subtracting 1960 from 2000 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
When dividing 400 by 280, we get 1 with a remainder of 120.
The next digit of our result is 1. 
Result so far: 286501.8428571
If we subtract 280 from 400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
The next digit of our result is 4. 
Result so far: 286501.84285714
Subtract 1120 from 1200 to 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.

The final result is 286501.84285714 with a remainder of 8e-08.
