We divide 324288 by 78
The aim is to understand the frequency of 78 in 324288.

Moving on to step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 78

Advancing to step 2:
78 goes into 32 0 times with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 78

Let's proceed to step 3:
78 can be fit into 324 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 12 after subtracting 312 from 324.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 78

Moving on to step 4:
If we divide 122 by 78, we get 1 and a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 78 from 122 and we're left with 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 78

Advancing to step 5:
The number 78 fits into 448 5 times, leaving a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 415.0
Subtracting 390 from 448 leaves us with 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 78

On to step 6:
If we divide 588 by 78, we get 7 and a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 4157.0
If we take 546 away from 588, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
If we divide 420 by 78, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 4157.5
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 78 fits into 300 3 times, leaving a remainder of 66.
The next digit of our result is 3. 
Result so far: 4157.53
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 4157.538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
If we divide 360 by 78, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 4157.5384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
78 goes into 480 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 4157.53846
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
120 divided by 78 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 4157.538461
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
420 divided by 78 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 4157.5384615
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
If we divide 300 by 78, we get 3 and a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 4157.53846153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 4157.53846153 and a remainder of 6.6e-08.
