310575 divided by 51 
The aim is to understand the frequency of 51 in 310575.

Advancing to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 51

On to step 2:
When dividing 31 by 51, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 51

Moving on to step 3:
51 can be fit into 310 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 306 from 310 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 51

On to step 4:
51 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 60.0
If we subtract 0 from 45, we get 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 51

Going ahead to step 5:
51 can be fit into 457 8 times, resulting in a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 608.0
If we take 408 away from 457, we end up with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 51

Advancing to step 6:
51 can be fit into 495 9 times, resulting in a remainder of 36.
The next digit of our result is 9. 
Result so far: 6089.0
Deduct 459 from 495 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
If we divide 360 by 51, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 6089.7
Deduct 357 from 360 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
51 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 6089.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 6089.705
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
If we divide 450 by 51, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 6089.7058
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
If we divide 420 by 51, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 6089.70588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 6089.70588 with a remaining 1.2e-05.
