15407040 ÷ 765 
We're looking to find how many times 765 goes into 15407040.

Step 1:
765 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 765

Advancing to step 2:
The number 765 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 765

Step 3:
765 goes into 154 0 times with a remainder of 154.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 154 after subtracting 0 from 154.
Include the next digit (0) from the dividend after 154, then repeat: 1540 / 765

Advancing to step 4:
765 goes into 1540 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1530 from 1540 to get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 765

Step 5:
When dividing 107 by 765, we get 0 with a remainder of 107.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 107 to get 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 765

Advancing to step 6:
If we divide 1070 by 765, we get 1 and a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 201.0
Subtracting 765 from 1070 leaves us with 305.
Append the next digit (4) from the dividend to 305 and continue with: 3054 / 765

Going ahead to step 7:
3054 divided by 765 is 3 with a remainder of 759.
Use 3 as the next digit of our solution. 
Result so far: 2013.0
Subtract 2295 from 3054 to get 759.
Append the next digit (0) from the dividend to 759 and continue with: 7590 / 765

Advancing to step 8:
7590 divided by 765 is 9 with a remainder of 705.
Use 9 as the next digit of our solution. 
Result so far: 20139.0
Subtracting 6885 from 7590 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.

Moving on to step 9:
765 can be fit into 7050 9 times, resulting in a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 20139.9
The remainder is 165 after subtracting 6885 from 7050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 10:
765 can be fit into 1650 2 times, resulting in a remainder of 120.
The next digit of our result is 2. 
Result so far: 20139.92
Subtracting 1530 from 1650 leaves us 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.

Step 11:
765 goes into 1200 1 times with a remainder of 435.
Put 1 as the next digit of the answer. 
Result so far: 20139.921
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.

Step 12:
The number 765 fits into 4350 5 times, leaving a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 20139.9215
The remainder is 525 after subtracting 3825 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 13:
765 can be fit into 5250 6 times, resulting in a remainder of 660.
The number 6 becomes the next digit in our result. 
Result so far: 20139.92156
The remainder is 660 after subtracting 4590 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 14:
765 can be fit into 6600 8 times, resulting in a remainder of 480.
Put 8 as the next digit of the answer. 
Result so far: 20139.921568
If we subtract 6120 from 6600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 15:
4800 divided by 765 is 6 with a remainder of 210.
Record the quotient 6 as the next digit in the result. 
Result so far: 20139.9215686
If we take 4590 away from 4800, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 16:
765 can be fit into 2100 2 times, resulting in a remainder of 570.
Put 2 as the next digit of the answer. 
Result so far: 20139.92156862
Subtract 1530 from 2100 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

In conclusion, the division gives 20139.92156862 with a balance of 5.7e-07.
