51585360 ÷ 765 
Let's see how many times 765 fits into 51585360.

Let's proceed to step 1:
765 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 765

Let's proceed to step 2:
51 divided by 765 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 765

Moving on to step 3:
765 goes into 515 0 times with a remainder of 515.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 515 after subtracting 0 from 515.
Take the next digit (8) from the dividend and append it to 515, then repeat: 5158 / 765

Step 4:
765 goes into 5158 6 times with a remainder of 568.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 568 after subtracting 4590 from 5158.
Grab the next digit (5) from the dividend, add it to 568, then carry on: 5685 / 765

On to step 5:
5685 divided by 765 is 7 with a remainder of 330.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtracting 5355 from 5685 leaves us with 330.
Include the next digit (3) from the dividend after 330, then repeat: 3303 / 765

Moving on to step 6:
765 can be fit into 3303 4 times, resulting in a remainder of 243.
Record the quotient 4 as the next digit in the result. 
Result so far: 674.0
Subtract 3060 from 3303 to get 243.
Include the next digit (6) from the dividend after 243, then repeat: 2436 / 765

Moving on to step 7:
When dividing 2436 by 765, we get 3 with a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 6743.0
The remainder is 141 after subtracting 2295 from 2436.
Include the next digit (0) from the dividend after 141, then repeat: 1410 / 765

Step 8:
765 goes into 1410 1 times with a remainder of 645.
Use 1 as the next digit of our solution. 
Result so far: 67431.0
Deduct 765 from 1410 and we're left with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Going ahead to step 9:
When dividing 6450 by 765, we get 8 with a remainder of 330.
Use 8 as the next digit of our solution. 
Result so far: 67431.8
Subtracting 6120 from 6450 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
765 can be fit into 3300 4 times, resulting in a remainder of 240.
The next digit of our result is 4. 
Result so far: 67431.84
If we subtract 3060 from 3300, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 11:
2400 divided by 765 is 3 with a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 67431.843
If we subtract 2295 from 2400, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 12:
When dividing 1050 by 765, we get 1 with a remainder of 285.
Use 1 as the next digit of our solution. 
Result so far: 67431.8431
Subtract 765 from 1050 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 13:
When dividing 2850 by 765, we get 3 with a remainder of 555.
The next digit of our result is 3. 
Result so far: 67431.84313
If we subtract 2295 from 2850, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Advancing to step 14:
The number 765 fits into 5550 7 times, leaving a remainder of 195.
Write down 7 as next digit of the result. 
Result so far: 67431.843137
Subtracting 5355 from 5550 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 15:
1950 divided by 765 is 2 with a remainder of 420.
Use 2 as the next digit of our solution. 
Result so far: 67431.8431372
Deduct 1530 from 1950 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 16:
When dividing 4200 by 765, we get 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 67431.84313725
If we take 3825 away from 4200, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

In conclusion, the division gives 67431.84313725 with a balance of 3.75e-07.
