880459 divided by 51 
The aim is to understand the frequency of 51 in 880459.

On to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 51

Advancing to step 2:
When dividing 88 by 51, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 37 after subtracting 51 from 88.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 51

Advancing to step 3:
51 goes into 370 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 13 after subtracting 357 from 370.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 51

Moving on to step 4:
When dividing 134 by 51, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
If we take 102 away from 134, we end up with 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 51

Going ahead to step 5:
When dividing 325 by 51, we get 6 with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 1726.0
If we subtract 306 from 325, we get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 51

Going ahead to step 6:
199 divided by 51 is 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 17263.0
Subtracting 153 from 199 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.

Step 7:
51 can be fit into 460 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 17263.9
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.

Going ahead to step 8:
If we divide 10 by 51, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17263.9
If we subtract 0 from 10, 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.

On to step 9:
If we divide 100 by 51, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 17263.901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
51 goes into 490 9 times with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 17263.9019
If we subtract 459 from 490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
The number 51 fits into 310 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 17263.90196
Subtract 306 from 310 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.

Moving on to step 12:
51 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 17263.90196
Subtract 0 from 40 to 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.

Step 13:
400 divided by 51 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 17263.9019607
Subtract 357 from 400 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 14:
The number 51 fits into 430 8 times, leaving a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 17263.90196078
Deduct 408 from 430 and we're left 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.

The final outcome is 17263.90196078, with a leftover of 2.2e-08.
