78278817 divided by 328 
The aim is to understand the frequency of 328 in 78278817.

Advancing to step 1:
If we divide 7 by 328, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 328

Moving on to step 2:
If we divide 78 by 328, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 328

Step 3:
If we divide 782 by 328, we get 2 and a remainder of 126.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 656 from 782 and we're left with 126.
Fetch the next digit (7) from the dividend, attach it to 126 and continue: 1267 / 328

Going ahead to step 4:
When dividing 1267 by 328, we get 3 with a remainder of 283.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 984 from 1267, we get 283.
Include the next digit (8) from the dividend after 283, then repeat: 2838 / 328

Moving on to step 5:
2838 divided by 328 is 8 with a remainder of 214.
Put 8 as the next digit of the answer. 
Result so far: 238.0
Subtract 2624 from 2838 to get 214.
Include the next digit (8) from the dividend after 214, then repeat: 2148 / 328

Moving on to step 6:
The number 328 fits into 2148 6 times, leaving a remainder of 180.
The next digit of our result is 6. 
Result so far: 2386.0
Subtract 1968 from 2148 to get 180.
Bring next digit (1) of the dividend behind the 180 and repeat the process: 1801 / 328

Going ahead to step 7:
328 goes into 1801 5 times with a remainder of 161.
Record the quotient 5 as the next digit in the result. 
Result so far: 23865.0
Deduct 1640 from 1801 and we're left with 161.
Take the next digit (7) from the dividend and append it to 161, then repeat: 1617 / 328

Moving on to step 8:
328 can be fit into 1617 4 times, resulting in a remainder of 305.
The next digit of our result is 4. 
Result so far: 238654.0
The remainder is 305 after subtracting 1312 from 1617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 9:
When dividing 3050 by 328, we get 9 with a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 238654.9
If we take 2952 away from 3050, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
The number 328 fits into 980 2 times, leaving a remainder of 324.
The next digit of our result is 2. 
Result so far: 238654.92
Subtracting 656 from 980 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 11:
If we divide 3240 by 328, we get 9 and a remainder of 288.
Write down 9 as next digit of the result. 
Result so far: 238654.929
Subtract 2952 from 3240 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 12:
328 goes into 2880 8 times with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 238654.9298
If we subtract 2624 from 2880, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 13:
328 can be fit into 2560 7 times, resulting in a remainder of 264.
Record the quotient 7 as the next digit in the result. 
Result so far: 238654.92987
If we take 2296 away from 2560, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 14:
2640 divided by 328 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 238654.929878
If we take 2624 away from 2640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 15:
If we divide 160 by 328, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 238654.929878
If we subtract 0 from 160, 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.

Moving on to step 16:
When dividing 1600 by 328, we get 4 with a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 238654.92987804
The remainder is 288 after subtracting 1312 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

After the division, we end up with 238654.92987804 and a remainder of 2.88e-07.
