We divide 666649 by 78
The aim is to understand the frequency of 78 in 666649.

Going ahead to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 78

Step 2:
When dividing 66 by 78, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 78

On to step 3:
If we divide 666 by 78, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 624 from 666 and we're left with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 78

Step 4:
The number 78 fits into 426 5 times, leaving a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 85.0
The remainder is 36 after subtracting 390 from 426.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 78

Going ahead to step 5:
78 can be fit into 364 4 times, resulting in a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 854.0
If we subtract 312 from 364, we get 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 78

Let's proceed to step 6:
When dividing 529 by 78, we get 6 with a remainder of 61.
Record the quotient 6 as the next digit in the result. 
Result so far: 8546.0
Deduct 468 from 529 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
78 can be fit into 610 7 times, resulting in a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 8546.7
Subtracting 546 from 610 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.

Going ahead to step 8:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8546.78
Subtracting 624 from 640 leaves us 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.

Advancing to step 9:
If we divide 160 by 78, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 8546.782
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.

Advancing to step 10:
40 divided by 78 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8546.782
Deduct 0 from 40 and we're left 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.

Moving on to step 11:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 8546.78205
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.

Going ahead to step 12:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 8546.782051
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.

Step 13:
If we divide 220 by 78, we get 2 and a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 8546.7820512
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
78 goes into 640 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 8546.78205128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 8546.78205128 with a remaining 1.6e-08.
