Let's divide 361439 by 78
The aim is to understand the frequency of 78 in 361439.

Moving on to step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 78

On to step 2:
78 can be fit into 36 0 times, resulting in a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 78

Let's proceed to step 3:
78 goes into 361 4 times with a remainder of 49.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 312 from 361 to get 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 78

Moving on to step 4:
78 goes into 494 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 468 from 494, we get 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 78

Step 5:
263 divided by 78 is 3 with a remainder of 29.
The next digit of our result is 3. 
Result so far: 463.0
The remainder is 29 after subtracting 234 from 263.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 78

Going ahead to step 6:
299 divided by 78 is 3 with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 4633.0
If we take 234 away from 299, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 7:
The number 78 fits into 650 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 4633.8
If we take 624 away from 650, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
260 divided by 78 is 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 4633.83
Subtract 234 from 260 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
When dividing 260 by 78, we get 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 4633.833
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 4633.833, and the remainder is 0.0026.
