Let's divide 697271 by 78
The aim is to understand the frequency of 78 in 697271.

Advancing to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 78

Advancing to step 2:
69 divided by 78 is 0 with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Include the next digit (7) from the dividend after 69, then repeat: 697 / 78

Going ahead to step 3:
78 goes into 697 8 times with a remainder of 73.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 624 from 697 leaves us with 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 78

Step 4:
78 goes into 732 9 times with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 702 from 732 leaves us with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 78

Going ahead to step 5:
78 can be fit into 307 3 times, resulting in a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 893.0
Deduct 234 from 307 and we're left with 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 78

Step 6:
731 divided by 78 is 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 8939.0
Subtracting 702 from 731 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
290 divided by 78 is 3 with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 8939.3
Deduct 234 from 290 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 8939.37
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
78 goes into 140 1 times with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 8939.371
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 8939.3717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
When dividing 740 by 78, we get 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 8939.37179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 8939.371794
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
78 goes into 680 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 8939.3717948
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
If we divide 560 by 78, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 8939.37179487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 8939.37179487 and a remainder of 1.4e-08.
