156310 divided by 51 
The aim is to understand the frequency of 51 in 156310.

On to step 1:
1 divided by 51 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 51

Moving on to step 2:
51 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 51

Step 3:
51 can be fit into 156 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 153 from 156 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 51

Step 4:
51 can be fit into 33 0 times, resulting in a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 33 to get 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 51

Moving on to step 5:
51 goes into 331 6 times with a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 306.0
Subtract 306 from 331 to get 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 51

On to step 6:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 3064.0
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
51 can be fit into 460 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 3064.9
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
51 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3064.9
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 3064.901
Subtracting 51 from 100 leaves us 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.

Going ahead to step 10:
490 divided by 51 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 3064.9019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
310 divided by 51 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3064.90196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
If we divide 40 by 51, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3064.90196
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
The number 51 fits into 400 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 3064.9019607
If we subtract 357 from 400, we 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.
The number 8 becomes the next digit in our result. 
Result so far: 3064.90196078
Subtracting 408 from 430 leaves us 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 result is 3064.90196078 with a remainder of 2.2e-08.
