77439947 ÷ 277 
We want to divide 77439947 by 277.

Moving on to step 1:
277 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 277

Let's proceed to step 2:
77 divided by 277 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 277

Step 3:
When dividing 774 by 277, we get 2 with a remainder of 220.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 554 from 774 and we're left with 220.
Fetch the next digit (3) from the dividend, attach it to 220 and continue: 2203 / 277

Let's proceed to step 4:
If we divide 2203 by 277, we get 7 and a remainder of 264.
Write down 7 as next digit of the result. 
Result so far: 27.0
The remainder is 264 after subtracting 1939 from 2203.
Include the next digit (9) from the dividend after 264, then repeat: 2649 / 277

Step 5:
When dividing 2649 by 277, we get 9 with a remainder of 156.
Put 9 as the next digit of the answer. 
Result so far: 279.0
Deduct 2493 from 2649 and we're left with 156.
Take the next digit (9) from the dividend and append it to 156, then repeat: 1569 / 277

Step 6:
277 can be fit into 1569 5 times, resulting in a remainder of 184.
Write down 5 as next digit of the result. 
Result so far: 2795.0
Deduct 1385 from 1569 and we're left with 184.
Include the next digit (4) from the dividend after 184, then repeat: 1844 / 277

Going ahead to step 7:
277 goes into 1844 6 times with a remainder of 182.
Write down 6 as next digit of the result. 
Result so far: 27956.0
If we take 1662 away from 1844, we end up with 182.
Include the next digit (7) from the dividend after 182, then repeat: 1827 / 277

Step 8:
When dividing 1827 by 277, we get 6 with a remainder of 165.
Put 6 as the next digit of the answer. 
Result so far: 279566.0
If we take 1662 away from 1827, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 9:
277 goes into 1650 5 times with a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 279566.5
If we take 1385 away from 1650, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 10:
If we divide 2650 by 277, we get 9 and a remainder of 157.
Use 9 as the next digit of our solution. 
Result so far: 279566.59
Subtracting 2493 from 2650 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 11:
The number 277 fits into 1570 5 times, leaving a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 279566.595
If we take 1385 away from 1570, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 12:
If we divide 1850 by 277, we get 6 and a remainder of 188.
Record the quotient 6 as the next digit in the result. 
Result so far: 279566.5956
If we subtract 1662 from 1850, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 13:
277 can be fit into 1880 6 times, resulting in a remainder of 218.
Write down 6 as next digit of the result. 
Result so far: 279566.59566
Subtract 1662 from 1880 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final outcome is 279566.59566, with a leftover of 0.000218.
