760603 ÷ 78 
The aim is to understand the frequency of 78 in 760603.

On to step 1:
7 divided by 78 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 78

Step 2:
When dividing 76 by 78, we get 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Include the next digit (0) from the dividend after 76, then repeat: 760 / 78

Let's proceed to step 3:
If we divide 760 by 78, we get 9 and a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 702 from 760 to get 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 78

Step 4:
If we divide 586 by 78, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 546 from 586 and we're left with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 78

Let's proceed to step 5:
If we divide 400 by 78, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 975.0
Subtract 390 from 400 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 78

Going ahead to step 6:
The number 78 fits into 103 1 times, leaving a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 9751.0
If we take 78 away from 103, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
If we divide 250 by 78, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 9751.3
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 9751.32
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9751.32
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 9751.3205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
When dividing 100 by 78, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 9751.32051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
When dividing 220 by 78, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 9751.320512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
If we divide 640 by 78, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 9751.3205128
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 9751.32051282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 9751.32051282, with a leftover of 4e-09.
