297636 ÷ 78 
The aim is to understand the frequency of 78 in 297636.

Let's proceed to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 78

On to step 2:
78 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 78

Let's proceed to step 3:
If we divide 297 by 78, we get 3 and a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 234 from 297 to get 63.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 78

On to step 4:
When dividing 636 by 78, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 624 from 636 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 78

Step 5:
When dividing 123 by 78, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 381.0
If we take 78 away from 123, we end up with 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 78

Advancing to step 6:
If we divide 456 by 78, we get 5 and a remainder of 66.
The next digit of our result is 5. 
Result so far: 3815.0
Subtracting 390 from 456 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 7:
When dividing 660 by 78, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 3815.8
If we take 624 away from 660, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
360 divided by 78 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 3815.84
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 78, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 3815.846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 3815.8461
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
If we divide 420 by 78, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3815.84615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
300 divided by 78 is 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 3815.846153
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
660 divided by 78 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 3815.8461538
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
If we divide 360 by 78, we get 4 and a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 3815.84615384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 3815.84615384, with a leftover of 4.8e-08.
