350025 ÷ 78 
The aim is to understand the frequency of 78 in 350025.

Going ahead to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 78

Moving on to step 2:
35 divided by 78 is 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 78

Advancing to step 3:
78 goes into 350 4 times with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 38 after subtracting 312 from 350.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 78

Moving on to step 4:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 312 from 380, we get 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 78

Going ahead to step 5:
78 can be fit into 682 8 times, resulting in a remainder of 58.
The next digit of our result is 8. 
Result so far: 448.0
If we subtract 624 from 682, we get 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 78

Going ahead to step 6:
585 divided by 78 is 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 4487.0
The remainder is 39 after subtracting 546 from 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
78 goes into 390 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4487.5
If we take 390 away from 390, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 78, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4487.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
78 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4487.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4487.5, with a leftover of 0.0.
