We're dividing 20120659 by 280 
The aim is to understand the frequency of 280 in 20120659.

Going ahead to step 1:
2 divided by 280 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 280

Going ahead to step 2:
When dividing 20 by 280, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 280

Going ahead to step 3:
280 goes into 201 0 times with a remainder of 201.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 201 leaves us with 201.
Fetch the next digit (2) from the dividend, attach it to 201 and continue: 2012 / 280

Step 4:
The number 280 fits into 2012 7 times, leaving a remainder of 52.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 1960 from 2012 leaves us with 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 280

Going ahead to step 5:
When dividing 520 by 280, we get 1 with a remainder of 240.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we take 280 away from 520, we end up with 240.
Grab the next digit (6) from the dividend, add it to 240, then carry on: 2406 / 280

On to step 6:
280 goes into 2406 8 times with a remainder of 166.
Write down 8 as next digit of the result. 
Result so far: 718.0
Subtracting 2240 from 2406 leaves us with 166.
Grab the next digit (5) from the dividend, add it to 166, then carry on: 1665 / 280

Moving on to step 7:
If we divide 1665 by 280, we get 5 and a remainder of 265.
The next digit of our result is 5. 
Result so far: 7185.0
If we take 1400 away from 1665, we end up with 265.
Fetch the next digit (9) from the dividend, attach it to 265 and continue: 2659 / 280

On to step 8:
280 can be fit into 2659 9 times, resulting in a remainder of 139.
The next digit of our result is 9. 
Result so far: 71859.0
Subtract 2520 from 2659 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 9:
When dividing 1390 by 280, we get 4 with a remainder of 270.
Write down 4 as next digit of the result. 
Result so far: 71859.4
Subtract 1120 from 1390 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
280 can be fit into 2700 9 times, resulting in a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 71859.49
Deduct 2520 from 2700 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
1800 divided by 280 is 6 with a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 71859.496
If we subtract 1680 from 1800, we 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.

Advancing to step 12:
280 goes into 1200 4 times with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 71859.4964
Subtracting 1120 from 1200 leaves us 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.

Let's proceed to step 13:
280 can be fit into 800 2 times, resulting in a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 71859.49642
The remainder is 240 after subtracting 560 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
If we divide 2400 by 280, we get 8 and a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 71859.496428
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.

On to step 15:
1600 divided by 280 is 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 71859.4964285
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.

On to step 16:
When dividing 2000 by 280, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 71859.49642857
If we take 1960 away from 2000, we end up 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 71859.49642857 with a remaining 4e-08.
