410646 ÷ 78 
The aim is to understand the frequency of 78 in 410646.

Moving on to step 1:
When dividing 4 by 78, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 78

Moving on to step 2:
If we divide 41 by 78, we get 0 and a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 78

Let's proceed to step 3:
The number 78 fits into 410 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 390 from 410, we get 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 78

Let's proceed to step 4:
If we divide 206 by 78, we get 2 and a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we subtract 156 from 206, we get 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 78

On to step 5:
78 can be fit into 504 6 times, resulting in a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 526.0
If we take 468 away from 504, we end up with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 78

Let's proceed to step 6:
The number 78 fits into 366 4 times, leaving a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 5264.0
The remainder is 54 after subtracting 312 from 366.
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 7:
If we divide 540 by 78, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 5264.6
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.

Moving on to step 8:
When dividing 720 by 78, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 5264.69
If we take 702 away from 720, we end up 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.

On to step 9:
If we divide 180 by 78, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 5264.692
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
78 goes into 240 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 5264.6923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
78 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5264.6923
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
The number 78 fits into 600 7 times, leaving a remainder of 54.
The next digit of our result is 7. 
Result so far: 5264.692307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
When dividing 540 by 78, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 5264.6923076
Subtracting 468 from 540 leaves us 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.

Going ahead to step 14:
78 goes into 720 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 5264.69230769
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 5264.69230769 and a remainder of 1.8e-08.
