287788 ÷ 77 
We want to divide 287788 by 77.

On to step 1:
The number 77 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 77

On to step 2:
The number 77 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 77

Going ahead to step 3:
When dividing 287 by 77, we get 3 with a remainder of 56.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 231 from 287 to get 56.
Grab the next digit (7) from the dividend, add it to 56, then carry on: 567 / 77

Step 4:
77 can be fit into 567 7 times, resulting in a remainder of 28.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 539 from 567 leaves us with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 77

Advancing to step 5:
When dividing 288 by 77, we get 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 373.0
Subtract 231 from 288 to get 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 77

On to step 6:
If we divide 578 by 77, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 3737.0
Deduct 539 from 578 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
77 can be fit into 390 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3737.5
Subtract 385 from 390 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
When dividing 50 by 77, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 3737.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
When dividing 500 by 77, we get 6 with a remainder of 38.
The next digit of our result is 6. 
Result so far: 3737.506
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
380 divided by 77 is 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 3737.5064
Subtract 308 from 380 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
77 can be fit into 720 9 times, resulting in a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 3737.50649
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
77 goes into 270 3 times with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 3737.506493
If we subtract 231 from 270, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 13:
390 divided by 77 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3737.5064935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
When dividing 50 by 77, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 3737.5064935
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 3737.5064935, with a leftover of 5e-08.
