25016730 divided by 51 
The aim is to understand the frequency of 51 in 25016730.

Let's proceed to step 1:
If we divide 2 by 51, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 51

On to step 2:
25 divided by 51 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 51

Advancing to step 3:
If we divide 250 by 51, we get 4 and a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 204 from 250 and we're left with 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 51

On to step 4:
The number 51 fits into 461 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 49.0
The remainder is 2 after subtracting 459 from 461.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 51

Advancing to step 5:
If we divide 26 by 51, we get 0 and a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 490.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 51

Moving on to step 6:
The number 51 fits into 267 5 times, leaving a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 4905.0
Subtracting 255 from 267 leaves us with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 51

Step 7:
51 can be fit into 123 2 times, resulting in a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 49052.0
If we take 102 away from 123, we end up with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 51

Advancing to step 8:
When dividing 210 by 51, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 490524.0
Deduct 204 from 210 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.

Moving on to step 9:
60 divided by 51 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 490524.1
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
If we divide 90 by 51, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 490524.11
Deduct 51 from 90 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 490524.11 and a remainder of 0.039.
