44018523 ÷ 678 
The aim is to understand the frequency of 678 in 44018523.

Going ahead to step 1:
If we divide 4 by 678, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 678

Step 2:
678 goes into 44 0 times with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 678

Moving on to step 3:
678 can be fit into 440 0 times, resulting in a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 440, we get 440.
Append the next digit (1) from the dividend to 440 and continue with: 4401 / 678

Moving on to step 4:
When dividing 4401 by 678, we get 6 with a remainder of 333.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 4068 away from 4401, we end up with 333.
Include the next digit (8) from the dividend after 333, then repeat: 3338 / 678

Let's proceed to step 5:
3338 divided by 678 is 4 with a remainder of 626.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtract 2712 from 3338 to get 626.
Bring next digit (5) of the dividend behind the 626 and repeat the process: 6265 / 678

Advancing to step 6:
If we divide 6265 by 678, we get 9 and a remainder of 163.
The next digit of our result is 9. 
Result so far: 649.0
Subtracting 6102 from 6265 leaves us with 163.
Append the next digit (2) from the dividend to 163 and continue with: 1632 / 678

Step 7:
678 goes into 1632 2 times with a remainder of 276.
Write down 2 as next digit of the result. 
Result so far: 6492.0
Deduct 1356 from 1632 and we're left with 276.
Append the next digit (3) from the dividend to 276 and continue with: 2763 / 678

Going ahead to step 8:
When dividing 2763 by 678, we get 4 with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 64924.0
If we subtract 2712 from 2763, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
If we divide 510 by 678, we get 0 and a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 64924.0
Deduct 0 from 510 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 10:
678 goes into 5100 7 times with a remainder of 354.
Put 7 as the next digit of the answer. 
Result so far: 64924.07
Subtracting 4746 from 5100 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 11:
If we divide 3540 by 678, we get 5 and a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 64924.075
Deduct 3390 from 3540 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
678 can be fit into 1500 2 times, resulting in a remainder of 144.
The next digit of our result is 2. 
Result so far: 64924.0752
If we subtract 1356 from 1500, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 13:
If we divide 1440 by 678, we get 2 and a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 64924.07522
The remainder is 84 after subtracting 1356 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 64924.07522 with a remainder of 8.4e-05.
