Let's divide 79286084 by 280
The aim is to understand the frequency of 280 in 79286084.

Going ahead to step 1:
When dividing 7 by 280, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 280

Going ahead to step 2:
79 divided by 280 is 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 280

Moving on to step 3:
When dividing 792 by 280, we get 2 with a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 560 from 792 and we're left with 232.
Include the next digit (8) from the dividend after 232, then repeat: 2328 / 280

Moving on to step 4:
280 goes into 2328 8 times with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 2240 from 2328 and we're left with 88.
Take the next digit (6) from the dividend and append it to 88, then repeat: 886 / 280

Going ahead to step 5:
886 divided by 280 is 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 283.0
If we take 840 away from 886, we end up with 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 280

Step 6:
280 goes into 460 1 times with a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 2831.0
Deduct 280 from 460 and we're left with 180.
Bring next digit (8) of the dividend behind the 180 and repeat the process: 1808 / 280

Moving on to step 7:
280 can be fit into 1808 6 times, resulting in a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 28316.0
Subtracting 1680 from 1808 leaves us with 128.
Bring next digit (4) of the dividend behind the 128 and repeat the process: 1284 / 280

Going ahead to step 8:
1284 divided by 280 is 4 with a remainder of 164.
The next digit of our result is 4. 
Result so far: 283164.0
If we subtract 1120 from 1284, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 9:
If we divide 1640 by 280, we get 5 and a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 283164.5
Deduct 1400 from 1640 and we're left 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 10:
The number 280 fits into 2400 8 times, leaving a remainder of 160.
The next digit of our result is 8. 
Result so far: 283164.58
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.

Moving on to step 11:
When dividing 1600 by 280, we get 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 283164.585
If we take 1400 away from 1600, we end up 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.

Let's proceed to step 12:
280 goes into 2000 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 283164.5857
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.

Moving on to step 13:
If we divide 400 by 280, we get 1 and a remainder of 120.
The number 1 becomes the next digit in our result. 
Result so far: 283164.58571
The remainder is 120 after subtracting 280 from 400.
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 14:
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: 283164.585714
Deduct 1120 from 1200 and we're left with 80.
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 15:
If we divide 800 by 280, we get 2 and a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 283164.5857142
Subtracting 560 from 800 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.

Let's proceed to step 16:
2400 divided by 280 is 8 with a remainder of 160.
The next digit of our result is 8. 
Result so far: 283164.58571428
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.

The final outcome is 283164.58571428, with a leftover of 1.6e-07.
