We divide 25059 by 78
The aim is to understand the frequency of 78 in 25059.

Advancing to step 1:
2 divided by 78 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 78

Step 2:
If we divide 25 by 78, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 78

Advancing to step 3:
If we divide 250 by 78, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 234 from 250 and we're left with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 78

Let's proceed to step 4:
165 divided by 78 is 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Deduct 156 from 165 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 78

On to step 5:
The number 78 fits into 99 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 321.0
The remainder is 21 after subtracting 78 from 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 6:
When dividing 210 by 78, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 321.2
Subtract 156 from 210 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 321.26
If we subtract 468 from 540, we 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.

Let's proceed to step 8:
If we divide 720 by 78, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 321.269
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 78 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 321.2692
Deduct 156 from 180 and we're left 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.

Moving on to step 10:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 321.26923
Deduct 234 from 240 and we're left 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.

On to step 11:
If we divide 60 by 78, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 321.26923
If we take 0 away from 60, we end up 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.

Step 12:
600 divided by 78 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 321.2692307
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.

Let's proceed to step 13:
540 divided by 78 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 321.26923076
If we take 468 away from 540, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 321.26923076 with a remaining 7.2e-08.
