298524 ÷ 78 
The aim is to understand the frequency of 78 in 298524.

Going ahead to step 1:
78 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 78

Let's proceed to step 2:
78 can be fit into 29 0 times, resulting in a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 78

Advancing to step 3:
298 divided by 78 is 3 with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 234 from 298 and we're left with 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 78

Let's proceed to step 4:
When dividing 645 by 78, we get 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Deduct 624 from 645 and we're left with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 78

Step 5:
The number 78 fits into 212 2 times, leaving a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 382.0
The remainder is 56 after subtracting 156 from 212.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 78

Moving on to step 6:
The number 78 fits into 564 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 3827.0
If we take 546 away from 564, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 3827.2
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
When dividing 240 by 78, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3827.23
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 3827.23
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
600 divided by 78 is 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 3827.2307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 3827.23076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
720 divided by 78 is 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 3827.230769
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
If we divide 180 by 78, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 3827.2307692
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 78 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3827.23076923
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 3827.23076923 and a remainder of 6e-09.
