We look at the division of 78203798 by 809 
We're looking to find how many times 809 goes into 78203798.

Going ahead to step 1:
809 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 809

Advancing to step 2:
When dividing 78 by 809, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 809

Let's proceed to step 3:
The number 809 fits into 782 0 times, leaving a remainder of 782.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 782 after subtracting 0 from 782.
Include the next digit (0) from the dividend after 782, then repeat: 7820 / 809

On to step 4:
809 goes into 7820 9 times with a remainder of 539.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7281 from 7820 leaves us with 539.
Append the next digit (3) from the dividend to 539 and continue with: 5393 / 809

Advancing to step 5:
809 can be fit into 5393 6 times, resulting in a remainder of 539.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 539 after subtracting 4854 from 5393.
Fetch the next digit (7) from the dividend, attach it to 539 and continue: 5397 / 809

Let's proceed to step 6:
809 can be fit into 5397 6 times, resulting in a remainder of 543.
The next digit of our result is 6. 
Result so far: 966.0
Subtracting 4854 from 5397 leaves us with 543.
Include the next digit (9) from the dividend after 543, then repeat: 5439 / 809

Moving on to step 7:
5439 divided by 809 is 6 with a remainder of 585.
Put 6 as the next digit of the answer. 
Result so far: 9666.0
Subtracting 4854 from 5439 leaves us with 585.
Fetch the next digit (8) from the dividend, attach it to 585 and continue: 5858 / 809

Step 8:
809 goes into 5858 7 times with a remainder of 195.
Put 7 as the next digit of the answer. 
Result so far: 96667.0
Deduct 5663 from 5858 and we're left 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.

Step 9:
If we divide 1950 by 809, we get 2 and a remainder of 332.
Use 2 as the next digit of our solution. 
Result so far: 96667.2
If we take 1618 away from 1950, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 10:
809 goes into 3320 4 times with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 96667.24
Deduct 3236 from 3320 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
The number 809 fits into 840 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 96667.241
If we subtract 809 from 840, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 12:
310 divided by 809 is 0 with a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 96667.241
If we subtract 0 from 310, 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.

Advancing to step 13:
3100 divided by 809 is 3 with a remainder of 673.
The number 3 becomes the next digit in our result. 
Result so far: 96667.24103
Deduct 2427 from 3100 and we're left with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Step 14:
When dividing 6730 by 809, we get 8 with a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 96667.241038
The remainder is 258 after subtracting 6472 from 6730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 15:
809 goes into 2580 3 times with a remainder of 153.
Record the quotient 3 as the next digit in the result. 
Result so far: 96667.2410383
If we subtract 2427 from 2580, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 16:
809 goes into 1530 1 times with a remainder of 721.
Record the quotient 1 as the next digit in the result. 
Result so far: 96667.24103831
The remainder is 721 after subtracting 809 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

After the division, we end up with 96667.24103831 and a remainder of 7.21e-07.
