15995 ÷ 51 
We're looking to find how many times 51 goes into 15995.

Advancing to step 1:
1 divided by 51 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 51

Going ahead to step 2:
When dividing 15 by 51, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 51

Step 3:
When dividing 159 by 51, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 153 from 159 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 51

Moving on to step 4:
When dividing 69 by 51, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 51 from 69 and we're left with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 51

Step 5:
51 goes into 185 3 times with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 313.0
The remainder is 32 after subtracting 153 from 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 6:
When dividing 320 by 51, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 313.6
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
When dividing 140 by 51, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 313.62
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
When dividing 380 by 51, we get 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 313.627
The remainder is 23 after subtracting 357 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 313.6274
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.

Going ahead to step 10:
When dividing 260 by 51, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 313.62745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
50 divided by 51 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 313.62745
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 313.6274509
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.

On to step 13:
410 divided by 51 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 313.62745098
Subtracting 408 from 410 leaves us 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.

The final outcome is 313.62745098, with a leftover of 2e-09.
