51808536 ÷ 76 
Let's see how many times 76 fits into 51808536.

Going ahead to step 1:
If we divide 5 by 76, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 76

Let's proceed to step 2:
51 divided by 76 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 76

Step 3:
76 goes into 518 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 456 from 518 leaves us with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 76

Moving on to step 4:
When dividing 620 by 76, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtracting 608 from 620 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 76

Let's proceed to step 5:
The number 76 fits into 128 1 times, leaving a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 681.0
The remainder is 52 after subtracting 76 from 128.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 76

Going ahead to step 6:
76 can be fit into 525 6 times, resulting in a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 6816.0
The remainder is 69 after subtracting 456 from 525.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 76

Moving on to step 7:
The number 76 fits into 693 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 68169.0
Deduct 684 from 693 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 76

Advancing to step 8:
76 goes into 96 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 681691.0
If we take 76 away from 96, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 76 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 681691.2
Subtracting 152 from 200 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
When dividing 480 by 76, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 681691.26
If we subtract 456 from 480, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
76 can be fit into 240 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 681691.263
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
The number 76 fits into 120 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 681691.2631
The remainder is 44 after subtracting 76 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
If we divide 440 by 76, we get 5 and a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 681691.26315
If we take 380 away from 440, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
76 can be fit into 600 7 times, resulting in a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 681691.263157
Subtract 532 from 600 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 15:
If we divide 680 by 76, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 681691.2631578
Subtract 608 from 680 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.

Let's proceed to step 16:
If we divide 720 by 76, we get 9 and a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 681691.26315789
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.

After the division, we end up with 681691.26315789 and a remainder of 3.6e-08.
