We divide 142656 by 51
We want to figure out the number of times 142656 can be divided by 51.

Going ahead to step 1:
1 divided by 51 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 51

Advancing to step 2:
14 divided by 51 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 51

Step 3:
142 divided by 51 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 102 from 142 and we're left with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 51

Moving on to step 4:
If we divide 406 by 51, we get 7 and a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 357 from 406 to get 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 51

Advancing to step 5:
51 can be fit into 495 9 times, resulting in a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 279.0
Subtracting 459 from 495 leaves us with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 51

Let's proceed to step 6:
When dividing 366 by 51, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 2797.0
The remainder is 9 after subtracting 357 from 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
51 can be fit into 90 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 2797.1
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
The number 51 fits into 390 7 times, leaving a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 2797.17
The remainder is 33 after subtracting 357 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
330 divided by 51 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 2797.176
Subtracting 306 from 330 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
The number 51 fits into 240 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 2797.1764
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
51 can be fit into 360 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 2797.17647
If we take 357 away from 360, we end up 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.

On to step 12:
30 divided by 51 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2797.17647
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
51 goes into 300 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 2797.1764705
If we subtract 255 from 300, we 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.

Step 14:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 2797.17647058
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 2797.17647058, with a leftover of 4.2e-08.
