We divide 378435 by 78
The aim is to understand the frequency of 78 in 378435.

On to step 1:
78 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 78

Advancing to step 2:
78 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 78

Advancing to step 3:
The number 78 fits into 378 4 times, leaving a remainder of 66.
The next digit of our result is 4. 
Result so far: 4.0
If we take 312 away from 378, we end up with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 78

Moving on to step 4:
78 can be fit into 664 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we subtract 624 from 664, we get 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 78

Advancing to step 5:
403 divided by 78 is 5 with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 485.0
Subtract 390 from 403 to get 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 78

Going ahead to step 6:
If we divide 135 by 78, we get 1 and a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 4851.0
The remainder is 57 after subtracting 78 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
The number 78 fits into 570 7 times, leaving a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 4851.7
Deduct 546 from 570 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
If we divide 240 by 78, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 4851.73
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
When dividing 60 by 78, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 4851.73
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
600 divided by 78 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 4851.7307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
When dividing 540 by 78, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 4851.73076
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 4851.730769
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
78 goes into 180 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 4851.7307692
If we subtract 156 from 180, we 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.

Advancing to step 14:
240 divided by 78 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 4851.73076923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 4851.73076923 with a remainder of 6e-09.
