We divide 142886 by 77
We're looking to find how many times 77 goes into 142886.

Going ahead to step 1:
If we divide 1 by 77, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 77

Advancing to step 2:
77 goes into 14 0 times 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.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 77

Advancing to step 3:
142 divided by 77 is 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 77 from 142, we get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 77

Going ahead to step 4:
The number 77 fits into 658 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 616 from 658, we get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 77

Step 5:
77 can be fit into 428 5 times, resulting in a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 185.0
Subtract 385 from 428 to get 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 77

On to step 6:
77 can be fit into 436 5 times, resulting in a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 1855.0
The remainder is 51 after subtracting 385 from 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
The number 77 fits into 510 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 1855.6
Subtracting 462 from 510 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
77 goes into 480 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 1855.66
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 1855.66 with a remainder of 0.018.
