We look at the division of 20580336 by 76 
Let's see how many times 76 fits into 20580336.

Step 1:
When dividing 2 by 76, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 76

Moving on to step 2:
20 divided by 76 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 76

Going ahead to step 3:
76 can be fit into 205 2 times, resulting in a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 152 from 205 to get 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 76

On to step 4:
When dividing 538 by 76, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 532 from 538 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 76

Let's proceed to step 5:
76 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 270.0
Subtracting 0 from 60 leaves us with 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 76

On to step 6:
If we divide 603 by 76, we get 7 and a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 2707.0
Subtract 532 from 603 to get 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 76

Advancing to step 7:
713 divided by 76 is 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 27079.0
Subtract 684 from 713 to get 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 76

Moving on to step 8:
76 can be fit into 296 3 times, resulting in a remainder of 68.
The next digit of our result is 3. 
Result so far: 270793.0
Subtract 228 from 296 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.

On to step 9:
76 goes into 680 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 270793.8
Deduct 608 from 680 and we're left with 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 10:
76 goes into 720 9 times with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 270793.89
If we subtract 684 from 720, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
The number 76 fits into 360 4 times, leaving a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 270793.894
The remainder is 56 after subtracting 304 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
When dividing 560 by 76, we get 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 270793.8947
Subtract 532 from 560 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
280 divided by 76 is 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 270793.89473
The remainder is 52 after subtracting 228 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 14:
76 goes into 520 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 270793.894736
Deduct 456 from 520 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.

Step 15:
The number 76 fits into 640 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 270793.8947368
If we subtract 608 from 640, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 16:
The number 76 fits into 320 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 270793.89473684
Subtract 304 from 320 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 270793.89473684 with a remainder of 1.6e-08.
