756484 ÷ 78 
The aim is to understand the frequency of 78 in 756484.

On to step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 78

Step 2:
78 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Include the next digit (6) from the dividend after 75, then repeat: 756 / 78

Going ahead to step 3:
78 goes into 756 9 times with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 702 from 756 leaves us with 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 78

Going ahead to step 4:
78 can be fit into 544 6 times, resulting in a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Deduct 468 from 544 and we're left with 76.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 78

Moving on to step 5:
If we divide 768 by 78, we get 9 and a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 969.0
If we subtract 702 from 768, we get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 78

Moving on to step 6:
When dividing 664 by 78, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 9698.0
If we take 624 away from 664, we end up 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.

Step 7:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 9698.5
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 78, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 9698.51
If we subtract 78 from 100, we 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.

Let's proceed to step 9:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 9698.512
Subtract 156 from 220 to 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.

On to step 10:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9698.5128
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.

Step 11:
160 divided by 78 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 9698.51282
Subtracting 156 from 160 leaves us with 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 12:
If we divide 40 by 78, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9698.51282
If we take 0 away from 40, we end up 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.

On to step 13:
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: 9698.5128205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
When dividing 100 by 78, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 9698.51282051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 9698.51282051, and the remainder is 2.2e-08.
