We divide 30722340 by 280
The aim is to understand the frequency of 280 in 30722340.

Moving on to step 1:
3 divided by 280 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 280

On to step 2:
When dividing 30 by 280, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 280

Step 3:
280 goes into 307 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 280 from 307 to get 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 280

Going ahead to step 4:
272 divided by 280 is 0 with a remainder of 272.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 272, we end up with 272.
Bring next digit (2) of the dividend behind the 272 and repeat the process: 2722 / 280

Going ahead to step 5:
280 goes into 2722 9 times with a remainder of 202.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtracting 2520 from 2722 leaves us with 202.
Bring next digit (3) of the dividend behind the 202 and repeat the process: 2023 / 280

Let's proceed to step 6:
2023 divided by 280 is 7 with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 1097.0
Deduct 1960 from 2023 and we're left with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 280

On to step 7:
If we divide 634 by 280, we get 2 and a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 10972.0
If we take 560 away from 634, we end up with 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 280

Moving on to step 8:
The number 280 fits into 740 2 times, leaving a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 109722.0
The remainder is 180 after subtracting 560 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 9:
The number 280 fits into 1800 6 times, leaving a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 109722.6
Subtract 1680 from 1800 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.

Moving on to step 10:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 109722.64
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.

Advancing 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: 109722.642
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.

Advancing to step 12:
When dividing 2400 by 280, we get 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 109722.6428
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 13:
When dividing 1600 by 280, we get 5 with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 109722.64285
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.

Going ahead to step 14:
If we divide 2000 by 280, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 109722.642857
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.

Step 15:
The number 280 fits into 400 1 times, leaving a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 109722.6428571
Deduct 280 from 400 and we're left 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.

Moving on to step 16:
When dividing 1200 by 280, we get 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 109722.64285714
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.

The final result is 109722.64285714 with a remainder of 8e-08.
