439910 divided by 77 
We're looking to find how many times 77 goes into 439910.

Step 1:
77 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 77

Going ahead to step 2:
If we divide 43 by 77, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 77

On to step 3:
439 divided by 77 is 5 with a remainder of 54.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 385 from 439 to get 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 77

Moving on to step 4:
77 can be fit into 549 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Deduct 539 from 549 and we're left with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 77

Advancing to step 5:
If we divide 101 by 77, we get 1 and a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 571.0
The remainder is 24 after subtracting 77 from 101.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 77

Moving on to step 6:
77 can be fit into 240 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 5713.0
If we take 231 away from 240, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 77 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 5713.1
Subtract 77 from 90 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
The number 77 fits into 130 1 times, leaving a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 5713.11
Deduct 77 from 130 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 5713.11 and a remainder of 0.053.
