80654980 divided by 278 
The aim is to understand the frequency of 278 in 80654980.

Moving on to step 1:
278 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 278

On to step 2:
When dividing 80 by 278, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (6) from the dividend, attach it to 80 and continue: 806 / 278

Step 3:
278 can be fit into 806 2 times, resulting in a remainder of 250.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 250 after subtracting 556 from 806.
Append the next digit (5) from the dividend to 250 and continue with: 2505 / 278

Step 4:
If we divide 2505 by 278, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 2502 away from 2505, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 278

Moving on to step 5:
If we divide 34 by 278, we get 0 and a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 290.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 278

On to step 6:
278 can be fit into 349 1 times, resulting in a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 2901.0
Deduct 278 from 349 and we're left with 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 278

Step 7:
If we divide 718 by 278, we get 2 and a remainder of 162.
Use 2 as the next digit of our solution. 
Result so far: 29012.0
Subtract 556 from 718 to get 162.
Grab the next digit (0) from the dividend, add it to 162, then carry on: 1620 / 278

Step 8:
278 can be fit into 1620 5 times, resulting in a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 290125.0
If we take 1390 away from 1620, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
278 goes into 2300 8 times with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 290125.8
Subtracting 2224 from 2300 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
The number 278 fits into 760 2 times, leaving a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 290125.82
If we subtract 556 from 760, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 11:
When dividing 2040 by 278, we get 7 with a remainder of 94.
Use 7 as the next digit of our solution. 
Result so far: 290125.827
Subtract 1946 from 2040 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 12:
If we divide 940 by 278, we get 3 and a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 290125.8273
Subtracting 834 from 940 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 13:
The number 278 fits into 1060 3 times, leaving a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 290125.82733
Subtract 834 from 1060 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

In conclusion, the division gives 290125.82733 with a balance of 0.000226.
