Let's divide 51657087 by 765
We want to figure out the number of times 51657087 can be divided by 765.

On to step 1:
765 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 765

Going ahead to step 2:
765 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 765

Let's proceed to step 3:
The number 765 fits into 516 0 times, leaving a remainder of 516.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 516, we get 516.
Fetch the next digit (5) from the dividend, attach it to 516 and continue: 5165 / 765

On to step 4:
5165 divided by 765 is 6 with a remainder of 575.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4590 from 5165 to get 575.
Append the next digit (7) from the dividend to 575 and continue with: 5757 / 765

Advancing to step 5:
5757 divided by 765 is 7 with a remainder of 402.
The next digit of our result is 7. 
Result so far: 67.0
If we take 5355 away from 5757, we end up with 402.
Fetch the next digit (0) from the dividend, attach it to 402 and continue: 4020 / 765

Moving on to step 6:
765 goes into 4020 5 times with a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 675.0
If we subtract 3825 from 4020, we get 195.
Append the next digit (8) from the dividend to 195 and continue with: 1958 / 765

Going ahead to step 7:
When dividing 1958 by 765, we get 2 with a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 6752.0
If we subtract 1530 from 1958, we get 428.
Include the next digit (7) from the dividend after 428, then repeat: 4287 / 765

Advancing to step 8:
The number 765 fits into 4287 5 times, leaving a remainder of 462.
Write down 5 as next digit of the result. 
Result so far: 67525.0
Subtracting 3825 from 4287 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 9:
If we divide 4620 by 765, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 67525.6
Deduct 4590 from 4620 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
765 goes into 300 0 times with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 67525.6
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
The number 765 fits into 3000 3 times, leaving a remainder of 705.
Put 3 as the next digit of the answer. 
Result so far: 67525.603
Subtracting 2295 from 3000 leaves us with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

On to step 12:
If we divide 7050 by 765, we get 9 and a remainder of 165.
The next digit of our result is 9. 
Result so far: 67525.6039
Subtract 6885 from 7050 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 13:
If we divide 1650 by 765, we get 2 and a remainder of 120.
The next digit of our result is 2. 
Result so far: 67525.60392
Deduct 1530 from 1650 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
1200 divided by 765 is 1 with a remainder of 435.
Write down 1 as next digit of the result. 
Result so far: 67525.603921
Subtracting 765 from 1200 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 15:
765 goes into 4350 5 times with a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 67525.6039215
If we subtract 3825 from 4350, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 16:
The number 765 fits into 5250 6 times, leaving a remainder of 660.
Put 6 as the next digit of the answer. 
Result so far: 67525.60392156
If we take 4590 away from 5250, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

The quotient of the division is 67525.60392156, and the remainder is 6.6e-07.
