We're dividing 51407998 by 765 
We want to divide 51407998 by 765.

On to step 1:
765 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
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

Advancing to step 2:
If we divide 51 by 765, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 765

Step 3:
765 goes into 514 0 times with a remainder of 514.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 514, we get 514.
Grab the next digit (0) from the dividend, add it to 514, then carry on: 5140 / 765

Moving on to step 4:
When dividing 5140 by 765, we get 6 with a remainder of 550.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 4590 from 5140 and we're left with 550.
Grab the next digit (7) from the dividend, add it to 550, then carry on: 5507 / 765

Step 5:
5507 divided by 765 is 7 with a remainder of 152.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we take 5355 away from 5507, we end up with 152.
Fetch the next digit (9) from the dividend, attach it to 152 and continue: 1529 / 765

Let's proceed to step 6:
1529 divided by 765 is 1 with a remainder of 764.
Put 1 as the next digit of the answer. 
Result so far: 671.0
If we subtract 765 from 1529, we get 764.
Grab the next digit (9) from the dividend, add it to 764, then carry on: 7649 / 765

Step 7:
When dividing 7649 by 765, we get 9 with a remainder of 764.
Use 9 as the next digit of our solution. 
Result so far: 6719.0
Subtracting 6885 from 7649 leaves us with 764.
Grab the next digit (8) from the dividend, add it to 764, then carry on: 7648 / 765

Going ahead to step 8:
The number 765 fits into 7648 9 times, leaving a remainder of 763.
The next digit of our result is 9. 
Result so far: 67199.0
Deduct 6885 from 7648 and we're left with 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

On to step 9:
765 goes into 7630 9 times with a remainder of 745.
Record the quotient 9 as the next digit in the result. 
Result so far: 67199.9
If we take 6885 away from 7630, we end up with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Advancing to step 10:
765 can be fit into 7450 9 times, resulting in a remainder of 565.
Write down 9 as next digit of the result. 
Result so far: 67199.99
The remainder is 565 after subtracting 6885 from 7450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

In conclusion, the division gives 67199.99 with a balance of 0.565.
