We divide 258250 by 51
The aim is to understand the frequency of 51 in 258250.

On to step 1:
51 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 51

Going ahead to step 2:
When dividing 25 by 51, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 51

Moving on to step 3:
When dividing 258 by 51, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 255 from 258 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 51

Step 4:
The number 51 fits into 32 0 times, leaving a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtracting 0 from 32 leaves us with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 51

Advancing to step 5:
If we divide 325 by 51, we get 6 and a remainder of 19.
The next digit of our result is 6. 
Result so far: 506.0
Subtracting 306 from 325 leaves us with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 51

Let's proceed to step 6:
When dividing 190 by 51, we get 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 5063.0
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 5063.7
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
51 goes into 130 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 5063.72
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
When dividing 280 by 51, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5063.725
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
If we divide 250 by 51, we get 4 and a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 5063.7254
Subtracting 204 from 250 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
460 divided by 51 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 5063.72549
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
51 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 5063.72549
Subtract 0 from 10 to 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.

On to step 13:
The number 51 fits into 100 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 5063.7254901
Deduct 51 from 100 and we're left 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.

Moving on to step 14:
When dividing 490 by 51, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 5063.72549019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 5063.72549019 with a remaining 3.1e-08.
