Let's divide 45644 by 78
The aim is to understand the frequency of 78 in 45644.

Let's proceed to step 1:
78 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 78

On to step 2:
The number 78 fits into 45 0 times, leaving 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.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 78

Moving on to step 3:
78 can be fit into 456 5 times, resulting in a remainder of 66.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 390 from 456 to get 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 78

Step 4:
When dividing 664 by 78, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Deduct 624 from 664 and we're left with 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 78

Let's proceed to step 5:
The number 78 fits into 404 5 times, leaving a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 585.0
If we subtract 390 from 404, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 6:
78 goes into 140 1 times with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 585.1
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
78 goes into 620 7 times with a remainder of 74.
The next digit of our result is 7. 
Result so far: 585.17
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 8:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 585.179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 585.1794
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
If we divide 680 by 78, we get 8 and a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 585.17948
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
When dividing 560 by 78, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 585.179487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
78 goes into 140 1 times with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 585.1794871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 13:
If we divide 620 by 78, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 585.17948717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 585.17948717 with a remainder of 7.4e-08.
