We're dividing 77504363 by 286 
Let's see how many times 286 fits into 77504363.

Advancing to step 1:
When dividing 7 by 286, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 286

Step 2:
When dividing 77 by 286, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 286

Going ahead to step 3:
775 divided by 286 is 2 with a remainder of 203.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 572 away from 775, we end up with 203.
Append the next digit (0) from the dividend to 203 and continue with: 2030 / 286

Advancing to step 4:
The number 286 fits into 2030 7 times, leaving a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 2002 from 2030 and we're left with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 286

Let's proceed to step 5:
When dividing 284 by 286, we get 0 with a remainder of 284.
Use 0 as the next digit of our solution. 
Result so far: 270.0
The remainder is 284 after subtracting 0 from 284.
Fetch the next digit (3) from the dividend, attach it to 284 and continue: 2843 / 286

Step 6:
The number 286 fits into 2843 9 times, leaving a remainder of 269.
Put 9 as the next digit of the answer. 
Result so far: 2709.0
If we take 2574 away from 2843, we end up with 269.
Take the next digit (6) from the dividend and append it to 269, then repeat: 2696 / 286

Advancing to step 7:
The number 286 fits into 2696 9 times, leaving a remainder of 122.
Put 9 as the next digit of the answer. 
Result so far: 27099.0
Subtract 2574 from 2696 to get 122.
Bring next digit (3) of the dividend behind the 122 and repeat the process: 1223 / 286

Advancing to step 8:
If we divide 1223 by 286, we get 4 and a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 270994.0
Subtract 1144 from 1223 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
The number 286 fits into 790 2 times, leaving a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 270994.2
If we take 572 away from 790, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 10:
286 goes into 2180 7 times with a remainder of 178.
Write down 7 as next digit of the result. 
Result so far: 270994.27
Deduct 2002 from 2180 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 11:
If we divide 1780 by 286, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 270994.276
Deduct 1716 from 1780 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
The number 286 fits into 640 2 times, leaving a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 270994.2762
Subtract 572 from 640 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 13:
If we divide 680 by 286, we get 2 and a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 270994.27622
If we subtract 572 from 680, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 270994.27622 and a remainder of 0.000108.
