We're dividing 630757 by 78 
The aim is to understand the frequency of 78 in 630757.

On to step 1:
6 divided by 78 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 78

Advancing to step 2:
When dividing 63 by 78, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 78

Let's proceed to step 3:
630 divided by 78 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 624 from 630 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 78

Let's proceed to step 4:
78 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Deduct 0 from 67 and we're left with 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 78

Going ahead to step 5:
675 divided by 78 is 8 with a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 808.0
Deduct 624 from 675 and we're left with 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 78

Advancing to step 6:
517 divided by 78 is 6 with a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 8086.0
If we take 468 away from 517, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
When dividing 490 by 78, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 8086.6
The remainder is 22 after subtracting 468 from 490.
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 8:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 8086.62
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.

Advancing to step 9:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8086.628
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 78, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 8086.6282
Subtract 156 from 160 to 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 11:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8086.6282
Subtract 0 from 40 to get 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 12:
78 can be fit into 400 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 8086.628205
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.

Step 13:
78 goes into 100 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 8086.6282051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
78 goes into 220 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 8086.62820512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 8086.62820512, and the remainder is 6.4e-08.
