649693 divided by 78 
The aim is to understand the frequency of 78 in 649693.

Moving on to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 78

Advancing to step 2:
When dividing 64 by 78, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 78

Let's proceed to step 3:
The number 78 fits into 649 8 times, leaving a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 624 from 649 to get 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 78

Moving on to step 4:
When dividing 256 by 78, we get 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 83.0
If we take 234 away from 256, we end up with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 78

Going ahead to step 5:
If we divide 229 by 78, we get 2 and a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 832.0
If we subtract 156 from 229, we get 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 78

Moving on to step 6:
733 divided by 78 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 8329.0
Subtracting 702 from 733 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
78 can be fit into 310 3 times, resulting in a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 8329.3
Subtracting 234 from 310 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 8:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 8329.39
Subtracting 702 from 760 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 8329.397
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 78, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 8329.3974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
When dividing 280 by 78, we get 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 8329.39743
Subtracting 234 from 280 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 8329.397435
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 8329.3974358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
78 goes into 760 9 times with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 8329.39743589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 8329.39743589 with a remaining 5.8e-08.
