Let's divide 93856903 by 280
The aim is to understand the frequency of 280 in 93856903.

Step 1:
The number 280 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 280

Let's proceed to step 2:
280 goes into 93 0 times with a remainder of 93.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 93 leaves us with 93.
Grab the next digit (8) from the dividend, add it to 93, then carry on: 938 / 280

Going ahead to step 3:
280 can be fit into 938 3 times, resulting in a remainder of 98.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 840 from 938 to get 98.
Bring next digit (5) of the dividend behind the 98 and repeat the process: 985 / 280

Going ahead to step 4:
When dividing 985 by 280, we get 3 with a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtract 840 from 985 to get 145.
Take the next digit (6) from the dividend and append it to 145, then repeat: 1456 / 280

Step 5:
280 goes into 1456 5 times with a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 335.0
If we subtract 1400 from 1456, we get 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 280

On to step 6:
280 goes into 569 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 3352.0
If we subtract 560 from 569, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 280

Moving on to step 7:
The number 280 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 33520.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 280

Let's proceed to step 8:
If we divide 903 by 280, we get 3 and a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 335203.0
Deduct 840 from 903 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
630 divided by 280 is 2 with a remainder of 70.
The next digit of our result is 2. 
Result so far: 335203.2
Subtract 560 from 630 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
The number 280 fits into 700 2 times, leaving a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 335203.22
Subtract 560 from 700 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 335203.22 and a remainder of 0.14.
