42886 ÷ 77 
We're looking to find how many times 77 goes into 42886.

Advancing to step 1:
4 divided by 77 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 77

Step 2:
42 divided by 77 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 77

Let's proceed to step 3:
77 can be fit into 428 5 times, resulting in a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 385 from 428 and we're left with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 77

Let's proceed to step 4:
77 goes into 438 5 times with a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we subtract 385 from 438, we get 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 77

Going ahead to step 5:
77 goes into 536 6 times with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 556.0
The remainder is 74 after subtracting 462 from 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 6:
The number 77 fits into 740 9 times, leaving a remainder of 47.
The next digit of our result is 9. 
Result so far: 556.9
If we subtract 693 from 740, 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.

Step 7:
77 goes into 470 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 556.96
If we subtract 462 from 470, 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 8:
If we divide 80 by 77, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 556.961
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
When dividing 30 by 77, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 556.961
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
77 can be fit into 300 3 times, resulting in a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 556.96103
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 11:
77 goes into 690 8 times with a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 556.961038
Deduct 616 from 690 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
77 goes into 740 9 times with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 556.9610389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
470 divided by 77 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 556.96103896
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 556.96103896, with a leftover of 8e-09.
