Let's divide 231512 by 51
We want to figure out the number of times 231512 can be divided by 51.

Advancing to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 51

Moving on to step 2:
51 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 51

Going ahead to step 3:
51 goes into 231 4 times with a remainder of 27.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 27 after subtracting 204 from 231.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 51

Advancing to step 4:
The number 51 fits into 275 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 255 away from 275, we end up with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 51

Let's proceed to step 5:
When dividing 201 by 51, we get 3 with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 453.0
Deduct 153 from 201 and we're left with 48.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 51

Going ahead to step 6:
482 divided by 51 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 4539.0
Subtract 459 from 482 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
When dividing 230 by 51, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4539.4
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
260 divided by 51 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4539.45
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
When dividing 50 by 51, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4539.45
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 51 fits into 500 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 4539.4509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 11:
410 divided by 51 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 4539.45098
If we take 408 away from 410, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
If we divide 20 by 51, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4539.45098
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
200 divided by 51 is 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 4539.4509803
If we subtract 153 from 200, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
When dividing 470 by 51, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 4539.45098039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 4539.45098039 with a remainder of 1.1e-08.
