We look at the division of 205390 by 78 
The aim is to understand the frequency of 78 in 205390.

Let's proceed to step 1:
78 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 78

Advancing to step 2:
If we divide 20 by 78, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 78

Let's proceed to step 3:
If we divide 205 by 78, we get 2 and a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 156 away from 205, we end up with 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 78

Going ahead to step 4:
If we divide 493 by 78, we get 6 and a remainder of 25.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 468 from 493 to get 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 78

Going ahead to step 5:
When dividing 259 by 78, we get 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 263.0
Subtracting 234 from 259 leaves us with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 78

Let's proceed to step 6:
78 can be fit into 250 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 2633.0
Subtract 234 from 250 to get 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 7:
When dividing 160 by 78, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2633.2
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.

Going ahead to step 8:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2633.2
Deduct 0 from 40 and we're left 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.

Advancing to step 9:
78 can be fit into 400 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2633.205
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 10:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 2633.2051
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 11:
220 divided by 78 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 2633.20512
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.

Let's proceed to step 12:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 2633.205128
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.

Going ahead to step 13:
The number 78 fits into 160 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2633.2051282
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.

On to step 14:
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: 2633.2051282
If we subtract 0 from 40, we 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.

The final outcome is 2633.2051282, with a leftover of 4e-08.
