We're dividing 80564536 by 278 
The aim is to understand the frequency of 278 in 80564536.

On to step 1:
If we divide 8 by 278, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 278

Step 2:
80 divided by 278 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 278

On to step 3:
278 goes into 805 2 times with a remainder of 249.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 556 away from 805, we end up with 249.
Append the next digit (6) from the dividend to 249 and continue with: 2496 / 278

On to step 4:
278 can be fit into 2496 8 times, resulting in a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 2224 away from 2496, we end up with 272.
Fetch the next digit (4) from the dividend, attach it to 272 and continue: 2724 / 278

Going ahead to step 5:
The number 278 fits into 2724 9 times, leaving a remainder of 222.
The next digit of our result is 9. 
Result so far: 289.0
If we subtract 2502 from 2724, we get 222.
Grab the next digit (5) from the dividend, add it to 222, then carry on: 2225 / 278

Advancing to step 6:
278 goes into 2225 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 2898.0
If we subtract 2224 from 2225, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 278

Going ahead to step 7:
278 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 28980.0
If we take 0 away from 13, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 278

Going ahead to step 8:
136 divided by 278 is 0 with a remainder of 136.
Put 0 as the next digit of the answer. 
Result so far: 289800.0
If we take 0 away from 136, we end up 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.

Moving on to step 9:
If we divide 1360 by 278, we get 4 and a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 289800.4
Subtracting 1112 from 1360 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 10:
2480 divided by 278 is 8 with a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 289800.48
Subtracting 2224 from 2480 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 11:
When dividing 2560 by 278, we get 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 289800.489
Subtract 2502 from 2560 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
278 can be fit into 580 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 289800.4892
Subtract 556 from 580 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
240 divided by 278 is 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 289800.4892
If we take 0 away from 240, we end up 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.

On to step 14:
278 goes into 2400 8 times with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 289800.489208
Subtracting 2224 from 2400 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 15:
When dividing 1760 by 278, we get 6 with a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 289800.4892086
Subtracting 1668 from 1760 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 16:
If we divide 920 by 278, we get 3 and a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 289800.48920863
Subtract 834 from 920 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 289800.48920863 and a remainder of 8.6e-08.
