We're dividing 425356 by 78 
The aim is to understand the frequency of 78 in 425356.

Going ahead to step 1:
When dividing 4 by 78, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 78

Let's proceed to step 2:
78 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 78

Advancing to step 3:
The number 78 fits into 425 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 390 from 425 leaves us with 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 78

Advancing to step 4:
The number 78 fits into 353 4 times, leaving a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we subtract 312 from 353, we get 41.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 78

On to step 5:
78 goes into 415 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 545.0
Deduct 390 from 415 and we're left with 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 78

On to step 6:
78 goes into 256 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 5453.0
If we take 234 away from 256, we end up 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.

Moving on to step 7:
The number 78 fits into 220 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 5453.2
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.

Advancing to step 8:
When dividing 640 by 78, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 5453.28
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.

Let's proceed to step 9:
If we divide 160 by 78, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 5453.282
Deduct 156 from 160 and we're left 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.

Advancing to step 10:
When dividing 40 by 78, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 5453.282
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.

Let's proceed to step 11:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5453.28205
If we subtract 390 from 400, we get 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 12:
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: 5453.282051
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.

Going ahead to step 13:
When dividing 220 by 78, we get 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 5453.2820512
Subtracting 156 from 220 leaves us 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.

Step 14:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 5453.28205128
Subtracting 624 from 640 leaves us 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.

The quotient of the division is 5453.28205128, and the remainder is 1.6e-08.
