We divide 319409 by 78
The aim is to understand the frequency of 78 in 319409.

Advancing to step 1:
78 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 78

Advancing to step 2:
The number 78 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 78

Moving on to step 3:
78 can be fit into 319 4 times, resulting in a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 7 after subtracting 312 from 319.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 78

Going ahead to step 4:
The number 78 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 74, we get 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 78

Moving on to step 5:
The number 78 fits into 740 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 409.0
If we take 702 away from 740, we end up with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 78

Going ahead to step 6:
When dividing 389 by 78, we get 4 with a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 4094.0
The remainder is 77 after subtracting 312 from 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 7:
770 divided by 78 is 9 with a remainder of 68.
The next digit of our result is 9. 
Result so far: 4094.9
If we take 702 away from 770, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
680 divided by 78 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 4094.98
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
560 divided by 78 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 4094.987
Deduct 546 from 560 and we're left with 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 10:
If we divide 140 by 78, we get 1 and a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 4094.9871
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.

Let's proceed to step 11:
If we divide 620 by 78, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 4094.98717
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.

Moving on to step 12:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 4094.987179
If we take 702 away from 740, we end up 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.

Let's proceed to step 13:
380 divided by 78 is 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 4094.9871794
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
78 goes into 680 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 4094.98717948
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.

The final outcome is 4094.98717948, with a leftover of 5.6e-08.
