Let's divide 912209 by 78
The aim is to understand the frequency of 78 in 912209.

Advancing to step 1:
78 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 78

On to step 2:
91 divided by 78 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 78 away from 91, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 78

Going ahead to step 3:
The number 78 fits into 132 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 78 from 132 leaves us with 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 78

Let's proceed to step 4:
78 goes into 542 6 times with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Deduct 468 from 542 and we're left with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 78

On to step 5:
The number 78 fits into 740 9 times, leaving a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 1169.0
Deduct 702 from 740 and we're left with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 78

Step 6:
78 can be fit into 389 4 times, resulting in a remainder of 77.
The number 4 becomes the next digit in our result. 
Result so far: 11694.0
The remainder is 77 after subtracting 312 from 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 7:
78 can be fit into 770 9 times, resulting in a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 11694.9
If we subtract 702 from 770, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
If we divide 680 by 78, we get 8 and a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 11694.98
Subtracting 624 from 680 leaves us 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.

Let's proceed to step 9:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 11694.987
Deduct 546 from 560 and we're left 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.

On to step 10:
When dividing 140 by 78, we get 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 11694.9871
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
620 divided by 78 is 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 11694.98717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
78 goes into 740 9 times with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 11694.987179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
If we divide 380 by 78, we get 4 and a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 11694.9871794
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
When dividing 680 by 78, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 11694.98717948
Deduct 624 from 680 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.

Our division results in 11694.98717948 with a remaining 5.6e-08.
