897522 divided by 78 
The aim is to understand the frequency of 78 in 897522.

Let's proceed to step 1:
8 divided by 78 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 78

Going ahead to step 2:
If we divide 89 by 78, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 78 from 89 and we're left with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 78

Step 3:
78 goes into 117 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 78 away from 117, we end up with 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 78

Going ahead to step 4:
78 can be fit into 395 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 115.0
The remainder is 5 after subtracting 390 from 395.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 78

Step 5:
78 can be fit into 52 0 times, resulting in a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 1150.0
If we take 0 away from 52, we end up with 52.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 78

On to step 6:
78 can be fit into 522 6 times, resulting in a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 11506.0
If we take 468 away from 522, we end up 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.

Advancing to step 7:
540 divided by 78 is 6 with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 11506.6
Subtracting 468 from 540 leaves us with 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 8:
78 goes into 720 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 11506.69
Subtracting 702 from 720 leaves us 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.

Step 9:
If we divide 180 by 78, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 11506.692
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.

Let's proceed to step 10:
If we divide 240 by 78, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 11506.6923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
78 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 11506.6923
If we subtract 0 from 60, we 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.

Going ahead to step 12:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 11506.692307
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
540 divided by 78 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 11506.6923076
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
If we divide 720 by 78, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 11506.69230769
If we take 702 away from 720, 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.

After the division, we end up with 11506.69230769 and a remainder of 1.8e-08.
