361417 ÷ 78 
The aim is to understand the frequency of 78 in 361417.

Step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 78

Advancing to step 2:
If we divide 36 by 78, we get 0 and a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 78

Advancing to step 3:
361 divided by 78 is 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 312 from 361 leaves us with 49.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 78

Let's proceed to step 4:
When dividing 494 by 78, we get 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Deduct 468 from 494 and we're left with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 78

Moving on to step 5:
When dividing 261 by 78, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 463.0
If we take 234 away from 261, we end up with 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 78

Let's proceed to step 6:
When dividing 277 by 78, we get 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 4633.0
Subtracting 234 from 277 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
If we divide 430 by 78, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 4633.5
The remainder is 40 after subtracting 390 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4633.55
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 4633.55 and a remainder of 0.01.
