We're dividing 451816 by 78 
The aim is to understand the frequency of 78 in 451816.

Let's proceed to step 1:
4 divided by 78 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 78

Moving on to step 2:
78 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 78

Going ahead to step 3:
78 can be fit into 451 5 times, resulting in a remainder of 61.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 390 from 451 leaves us with 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 78

Let's proceed to step 4:
78 goes into 618 7 times with a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 57.0
The remainder is 72 after subtracting 546 from 618.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 78

Let's proceed to step 5:
The number 78 fits into 721 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 579.0
If we take 702 away from 721, we end up with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 78

On to step 6:
The number 78 fits into 196 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 5792.0
If we subtract 156 from 196, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5792.5
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.

Step 8:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 5792.51
Subtract 78 from 100 to get 22.
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 9:
The number 78 fits into 220 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 5792.512
If we subtract 156 from 220, we get 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 10:
78 goes into 640 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 5792.5128
Deduct 624 from 640 and we're left 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 11:
78 goes into 160 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 5792.51282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 5792.51282
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5792.5128205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
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: 5792.51282051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 5792.51282051 with a remainder of 2.2e-08.
