We look at the division of 72725246 by 280 
The aim is to understand the frequency of 280 in 72725246.

Going ahead to step 1:
7 divided by 280 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 280

On to step 2:
If we divide 72 by 280, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (7) from the dividend, add it to 72, then carry on: 727 / 280

Going ahead to step 3:
If we divide 727 by 280, we get 2 and a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 560 away from 727, we end up with 167.
Grab the next digit (2) from the dividend, add it to 167, then carry on: 1672 / 280

Advancing to step 4:
280 goes into 1672 5 times with a remainder of 272.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 1400 from 1672 and we're left with 272.
Grab the next digit (5) from the dividend, add it to 272, then carry on: 2725 / 280

Let's proceed to step 5:
280 can be fit into 2725 9 times, resulting in a remainder of 205.
Record the quotient 9 as the next digit in the result. 
Result so far: 259.0
If we take 2520 away from 2725, we end up with 205.
Bring next digit (2) of the dividend behind the 205 and repeat the process: 2052 / 280

Advancing to step 6:
2052 divided by 280 is 7 with a remainder of 92.
The next digit of our result is 7. 
Result so far: 2597.0
The remainder is 92 after subtracting 1960 from 2052.
Bring next digit (4) of the dividend behind the 92 and repeat the process: 924 / 280

Moving on to step 7:
When dividing 924 by 280, we get 3 with a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 25973.0
The remainder is 84 after subtracting 840 from 924.
Include the next digit (6) from the dividend after 84, then repeat: 846 / 280

Going ahead to step 8:
The number 280 fits into 846 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 259733.0
If we subtract 840 from 846, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
60 divided by 280 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 259733.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
If we divide 600 by 280, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 259733.02
If we subtract 560 from 600, 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.

Let's proceed to step 11:
400 divided by 280 is 1 with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 259733.021
Subtracting 280 from 400 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.

On to step 12:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 259733.0214
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.

On to step 13:
If we divide 800 by 280, we get 2 and a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 259733.02142
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.

Step 14:
280 goes into 2400 8 times with a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 259733.021428
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.

Advancing to step 15:
1600 divided by 280 is 5 with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 259733.0214285
If we subtract 1400 from 1600, we 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.

Advancing to step 16:
The number 280 fits into 2000 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 259733.02142857
Deduct 1960 from 2000 and we're left 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.

The final outcome is 259733.02142857, with a leftover of 4e-08.
