We divide 80799140 by 278
The aim is to understand the frequency of 278 in 80799140.

Let's proceed to step 1:
278 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 278

Step 2:
The number 278 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 278

Moving on to step 3:
807 divided by 278 is 2 with a remainder of 251.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 556 from 807 leaves us with 251.
Take the next digit (9) from the dividend and append it to 251, then repeat: 2519 / 278

Advancing to step 4:
The number 278 fits into 2519 9 times, leaving a remainder of 17.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 17 after subtracting 2502 from 2519.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 278

Let's proceed to step 5:
179 divided by 278 is 0 with a remainder of 179.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
If we take 0 away from 179, we end up with 179.
Take the next digit (1) from the dividend and append it to 179, then repeat: 1791 / 278

Step 6:
If we divide 1791 by 278, we get 6 and a remainder of 123.
The next digit of our result is 6. 
Result so far: 2906.0
Subtracting 1668 from 1791 leaves us with 123.
Bring next digit (4) of the dividend behind the 123 and repeat the process: 1234 / 278

Going ahead to step 7:
278 goes into 1234 4 times with a remainder of 122.
The next digit of our result is 4. 
Result so far: 29064.0
Subtracting 1112 from 1234 leaves us with 122.
Bring next digit (0) of the dividend behind the 122 and repeat the process: 1220 / 278

Step 8:
278 goes into 1220 4 times with a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 290644.0
Subtract 1112 from 1220 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 9:
278 can be fit into 1080 3 times, resulting in a remainder of 246.
The next digit of our result is 3. 
Result so far: 290644.3
Subtract 834 from 1080 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 10:
When dividing 2460 by 278, we get 8 with a remainder of 236.
Write down 8 as next digit of the result. 
Result so far: 290644.38
Subtract 2224 from 2460 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 11:
278 can be fit into 2360 8 times, resulting in a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 290644.388
Subtracting 2224 from 2360 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 290644.388 and a remainder of 0.0136.
