We divide 752919 by 78
The aim is to understand the frequency of 78 in 752919.

Let's proceed to step 1:
If we divide 7 by 78, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 78

On to step 2:
75 divided by 78 is 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 78

Moving on to step 3:
If we divide 752 by 78, we get 9 and a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 702 from 752 and we're left with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 78

Let's proceed to step 4:
If we divide 509 by 78, we get 6 and a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we subtract 468 from 509, we get 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 78

Going ahead to step 5:
If we divide 411 by 78, we get 5 and a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 965.0
Deduct 390 from 411 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 78

Step 6:
78 can be fit into 219 2 times, resulting in a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 9652.0
The remainder is 63 after subtracting 156 from 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
78 goes into 630 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 9652.8
Subtracting 624 from 630 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
When dividing 60 by 78, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 9652.8
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.

Moving on to step 9:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 9652.807
Subtracting 546 from 600 leaves us 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.

Moving on to step 10:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 9652.8076
Subtract 468 from 540 to get 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 11:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 9652.80769
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.

On to step 12:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 9652.807692
If we take 156 away from 180, we end up 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.

Advancing to step 13:
78 goes into 240 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 9652.8076923
Subtract 234 from 240 to 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.

On to step 14:
When dividing 60 by 78, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 9652.8076923
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 9652.8076923, and the remainder is 6e-08.
