Let's divide 71124178 by 280
The aim is to understand the frequency of 280 in 71124178.

Let's proceed to step 1:
280 can be fit into 7 0 times, resulting in 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 / 280

On to step 2:
280 can be fit into 71 0 times, resulting in a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 280

Step 3:
280 goes into 711 2 times with a remainder of 151.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 560 from 711 to get 151.
Append the next digit (2) from the dividend to 151 and continue with: 1512 / 280

Moving on to step 4:
When dividing 1512 by 280, we get 5 with a remainder of 112.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 1400 from 1512 to get 112.
Fetch the next digit (4) from the dividend, attach it to 112 and continue: 1124 / 280

Advancing to step 5:
When dividing 1124 by 280, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 254.0
If we subtract 1120 from 1124, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 280

On to step 6:
280 goes into 41 0 times with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 2540.0
Deduct 0 from 41 and we're left with 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 280

Moving on to step 7:
If we divide 417 by 280, we get 1 and a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 25401.0
The remainder is 137 after subtracting 280 from 417.
Bring next digit (8) of the dividend behind the 137 and repeat the process: 1378 / 280

Step 8:
When dividing 1378 by 280, we get 4 with a remainder of 258.
Write down 4 as next digit of the result. 
Result so far: 254014.0
The remainder is 258 after subtracting 1120 from 1378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 9:
2580 divided by 280 is 9 with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 254014.9
The remainder is 60 after subtracting 2520 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
600 divided by 280 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 254014.92
Subtract 560 from 600 to 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.

Going ahead to step 11:
400 divided by 280 is 1 with a remainder of 120.
Record the quotient 1 as the next digit in the result. 
Result so far: 254014.921
Subtract 280 from 400 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.

Going ahead to step 12:
1200 divided by 280 is 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 254014.9214
If we take 1120 away from 1200, we end up 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 13:
280 can be fit into 800 2 times, resulting in a remainder of 240.
The next digit of our result is 2. 
Result so far: 254014.92142
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.

Moving on to step 14:
280 goes into 2400 8 times with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 254014.921428
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 15:
The number 280 fits into 1600 5 times, leaving a remainder of 200.
The next digit of our result is 5. 
Result so far: 254014.9214285
Subtract 1400 from 1600 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 16:
280 can be fit into 2000 7 times, resulting in a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 254014.92142857
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.

Our division results in 254014.92142857 with a remaining 4e-08.
