757350 divided by 78 
The aim is to understand the frequency of 78 in 757350.

Going ahead to step 1:
78 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 78

On to step 2:
75 divided by 78 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 78

On to step 3:
757 divided by 78 is 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 702 from 757 and we're left with 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 78

Step 4:
When dividing 553 by 78, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 97.0
The remainder is 7 after subtracting 546 from 553.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 78

Advancing to step 5:
When dividing 75 by 78, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 970.0
If we subtract 0 from 75, we get 75.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 78

Step 6:
750 divided by 78 is 9 with a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 9709.0
Subtract 702 from 750 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 9709.6
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 78 fits into 120 1 times, leaving a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 9709.61
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 9709.615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 9709.6153
Deduct 234 from 300 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
If we divide 660 by 78, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 9709.61538
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
When dividing 360 by 78, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 9709.615384
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 9709.6153846
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 9709.61538461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 9709.61538461, with a leftover of 4.2e-08.
