We divide 135146 by 51
We want to figure out the number of times 135146 can be divided by 51.

On to step 1:
51 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 51

Moving on to step 2:
51 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 51

Moving on to step 3:
If we divide 135 by 51, we get 2 and a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 102 away from 135, we end up with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 51

Going ahead to step 4:
51 can be fit into 331 6 times, resulting in a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtracting 306 from 331 leaves us with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 51

Advancing to step 5:
If we divide 254 by 51, we get 4 and a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 264.0
If we subtract 204 from 254, we get 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 51

Moving on to step 6:
The number 51 fits into 506 9 times, leaving a remainder of 47.
The next digit of our result is 9. 
Result so far: 2649.0
The remainder is 47 after subtracting 459 from 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
51 can be fit into 470 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 2649.9
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.

Let's proceed to step 8:
51 can be fit into 110 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2649.92
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
51 goes into 80 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 2649.921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
51 can be fit into 290 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2649.9215
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
If we divide 350 by 51, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2649.92156
Deduct 306 from 350 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
If we divide 440 by 51, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 2649.921568
Subtract 408 from 440 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
If we divide 320 by 51, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 2649.9215686
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
If we divide 140 by 51, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 2649.92156862
Subtracting 102 from 140 leaves us 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.

The final outcome is 2649.92156862, with a leftover of 3.8e-08.
