We look at the division of 65903945 by 805 
We want to figure out the number of times 65903945 can be divided by 805.

Step 1:
805 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 805

On to step 2:
The number 805 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 805

Moving on to step 3:
The number 805 fits into 659 0 times, leaving a remainder of 659.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 659 after subtracting 0 from 659.
Bring next digit (0) of the dividend behind the 659 and repeat the process: 6590 / 805

Advancing to step 4:
The number 805 fits into 6590 8 times, leaving a remainder of 150.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 6440 from 6590 to get 150.
Bring next digit (3) of the dividend behind the 150 and repeat the process: 1503 / 805

Going ahead to step 5:
1503 divided by 805 is 1 with a remainder of 698.
Use 1 as the next digit of our solution. 
Result so far: 81.0
The remainder is 698 after subtracting 805 from 1503.
Include the next digit (9) from the dividend after 698, then repeat: 6989 / 805

Advancing to step 6:
When dividing 6989 by 805, we get 8 with a remainder of 549.
Put 8 as the next digit of the answer. 
Result so far: 818.0
Subtract 6440 from 6989 to get 549.
Take the next digit (4) from the dividend and append it to 549, then repeat: 5494 / 805

Advancing to step 7:
The number 805 fits into 5494 6 times, leaving a remainder of 664.
Write down 6 as next digit of the result. 
Result so far: 8186.0
Subtract 4830 from 5494 to get 664.
Append the next digit (5) from the dividend to 664 and continue with: 6645 / 805

On to step 8:
6645 divided by 805 is 8 with a remainder of 205.
The number 8 becomes the next digit in our result. 
Result so far: 81868.0
If we take 6440 away from 6645, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 9:
805 goes into 2050 2 times with a remainder of 440.
Put 2 as the next digit of the answer. 
Result so far: 81868.2
Subtract 1610 from 2050 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 10:
When dividing 4400 by 805, we get 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 81868.25
If we subtract 4025 from 4400, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 11:
3750 divided by 805 is 4 with a remainder of 530.
Record the quotient 4 as the next digit in the result. 
Result so far: 81868.254
Subtract 3220 from 3750 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 12:
If we divide 5300 by 805, we get 6 and a remainder of 470.
The number 6 becomes the next digit in our result. 
Result so far: 81868.2546
If we subtract 4830 from 5300, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 13:
If we divide 4700 by 805, we get 5 and a remainder of 675.
Write down 5 as next digit of the result. 
Result so far: 81868.25465
Subtracting 4025 from 4700 leaves us with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Advancing to step 14:
805 goes into 6750 8 times with a remainder of 310.
The next digit of our result is 8. 
Result so far: 81868.254658
If we subtract 6440 from 6750, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 15:
805 goes into 3100 3 times with a remainder of 685.
Use 3 as the next digit of our solution. 
Result so far: 81868.2546583
If we subtract 2415 from 3100, we get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Going ahead to step 16:
The number 805 fits into 6850 8 times, leaving a remainder of 410.
Put 8 as the next digit of the answer. 
Result so far: 81868.25465838
Subtract 6440 from 6850 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

After the division, we end up with 81868.25465838 and a remainder of 4.1e-07.
