247721 ÷ 78 
The aim is to understand the frequency of 78 in 247721.

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
Subtracting 0 from 2 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 78

On to step 2:
If we divide 24 by 78, we get 0 and a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 78

Advancing to step 3:
The number 78 fits into 247 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 234 from 247 and we're left with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 78

Let's proceed to step 4:
137 divided by 78 is 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 78 away from 137, we end up with 59.
Grab the next digit (2) from the dividend, add it to 59, then carry on: 592 / 78

Let's proceed to step 5:
The number 78 fits into 592 7 times, leaving a remainder of 46.
The next digit of our result is 7. 
Result so far: 317.0
If we subtract 546 from 592, we get 46.
Take the next digit (1) from the dividend and append it to 46, then repeat: 461 / 78

Step 6:
If we divide 461 by 78, we get 5 and a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 3175.0
If we take 390 away from 461, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
The number 78 fits into 710 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 3175.9
Subtracting 702 from 710 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
78 goes into 80 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 3175.91
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
78 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3175.91
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 78, we get 2 and a remainder of 44.
The next digit of our result is 2. 
Result so far: 3175.9102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3175.91025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
When dividing 500 by 78, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 3175.910256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
If we divide 320 by 78, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 3175.9102564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
If we divide 80 by 78, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 3175.91025641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 3175.91025641, and the remainder is 2e-09.
