We divide 307018 by 78
The aim is to understand the frequency of 78 in 307018.

Step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 78

On to step 2:
30 divided by 78 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 78

Moving on to step 3:
78 can be fit into 307 3 times, resulting in a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 73 after subtracting 234 from 307.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 78

Advancing to step 4:
The number 78 fits into 730 9 times, leaving a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 702 from 730 to get 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 78

Advancing to step 5:
78 goes into 281 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 393.0
Subtracting 234 from 281 leaves us with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 78

Advancing to step 6:
The number 78 fits into 478 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 3936.0
Subtracting 468 from 478 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
When dividing 100 by 78, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 3936.1
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
220 divided by 78 is 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 3936.12
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
78 goes into 640 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3936.128
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
The number 78 fits into 160 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 3936.1282
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
78 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 3936.1282
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
78 goes into 400 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3936.128205
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
The number 78 fits into 100 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 3936.1282051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
220 divided by 78 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 3936.12820512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 3936.12820512 with a remainder of 6.4e-08.
