64131840 divided by 678 
The aim is to understand the frequency of 678 in 64131840.

On to step 1:
678 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 678

Advancing to step 2:
678 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 678

Let's proceed to step 3:
The number 678 fits into 641 0 times, leaving a remainder of 641.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 641 leaves us with 641.
Append the next digit (3) from the dividend to 641 and continue with: 6413 / 678

Going ahead to step 4:
If we divide 6413 by 678, we get 9 and a remainder of 311.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 6102 from 6413 leaves us with 311.
Include the next digit (1) from the dividend after 311, then repeat: 3111 / 678

Let's proceed to step 5:
When dividing 3111 by 678, we get 4 with a remainder of 399.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we subtract 2712 from 3111, we get 399.
Take the next digit (8) from the dividend and append it to 399, then repeat: 3998 / 678

Step 6:
The number 678 fits into 3998 5 times, leaving a remainder of 608.
Put 5 as the next digit of the answer. 
Result so far: 945.0
Subtract 3390 from 3998 to get 608.
Include the next digit (4) from the dividend after 608, then repeat: 6084 / 678

Let's proceed to step 7:
678 goes into 6084 8 times with a remainder of 660.
Use 8 as the next digit of our solution. 
Result so far: 9458.0
Subtracting 5424 from 6084 leaves us with 660.
Include the next digit (0) from the dividend after 660, then repeat: 6600 / 678

Step 8:
6600 divided by 678 is 9 with a remainder of 498.
Record the quotient 9 as the next digit in the result. 
Result so far: 94589.0
The remainder is 498 after subtracting 6102 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Moving on to step 9:
678 goes into 4980 7 times with a remainder of 234.
Put 7 as the next digit of the answer. 
Result so far: 94589.7
If we take 4746 away from 4980, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 10:
678 goes into 2340 3 times with a remainder of 306.
Use 3 as the next digit of our solution. 
Result so far: 94589.73
Deduct 2034 from 2340 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 11:
If we divide 3060 by 678, we get 4 and a remainder of 348.
Use 4 as the next digit of our solution. 
Result so far: 94589.734
Subtract 2712 from 3060 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 12:
3480 divided by 678 is 5 with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 94589.7345
If we subtract 3390 from 3480, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 13:
678 goes into 900 1 times with a remainder of 222.
Record the quotient 1 as the next digit in the result. 
Result so far: 94589.73451
If we take 678 away from 900, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 14:
If we divide 2220 by 678, we get 3 and a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 94589.734513
If we subtract 2034 from 2220, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 15:
The number 678 fits into 1860 2 times, leaving a remainder of 504.
Write down 2 as next digit of the result. 
Result so far: 94589.7345132
If we take 1356 away from 1860, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 16:
678 can be fit into 5040 7 times, resulting in a remainder of 294.
Record the quotient 7 as the next digit in the result. 
Result so far: 94589.73451327
Subtract 4746 from 5040 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

In conclusion, the division gives 94589.73451327 with a balance of 2.94e-07.
