We look at the division of 97885915 by 809 
Let's see how many times 809 fits into 97885915.

Step 1:
809 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 809

Step 2:
97 divided by 809 is 0 with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Bring next digit (8) of the dividend behind the 97 and repeat the process: 978 / 809

Going ahead to step 3:
809 goes into 978 1 times with a remainder of 169.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 809 from 978 leaves us with 169.
Grab the next digit (8) from the dividend, add it to 169, then carry on: 1698 / 809

Moving on to step 4:
If we divide 1698 by 809, we get 2 and a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 80 after subtracting 1618 from 1698.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 809

Step 5:
If we divide 805 by 809, we get 0 and a remainder of 805.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtracting 0 from 805 leaves us with 805.
Grab the next digit (9) from the dividend, add it to 805, then carry on: 8059 / 809

Going ahead to step 6:
The number 809 fits into 8059 9 times, leaving a remainder of 778.
Record the quotient 9 as the next digit in the result. 
Result so far: 1209.0
Deduct 7281 from 8059 and we're left with 778.
Append the next digit (1) from the dividend to 778 and continue with: 7781 / 809

Step 7:
809 can be fit into 7781 9 times, resulting in a remainder of 500.
Use 9 as the next digit of our solution. 
Result so far: 12099.0
Subtracting 7281 from 7781 leaves us with 500.
Bring next digit (5) of the dividend behind the 500 and repeat the process: 5005 / 809

Advancing to step 8:
809 can be fit into 5005 6 times, resulting in a remainder of 151.
Put 6 as the next digit of the answer. 
Result so far: 120996.0
If we take 4854 away from 5005, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 9:
1510 divided by 809 is 1 with a remainder of 701.
The next digit of our result is 1. 
Result so far: 120996.1
Deduct 809 from 1510 and we're left with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Let's proceed to step 10:
809 goes into 7010 8 times with a remainder of 538.
Use 8 as the next digit of our solution. 
Result so far: 120996.18
If we subtract 6472 from 7010, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 11:
When dividing 5380 by 809, we get 6 with a remainder of 526.
Write down 6 as next digit of the result. 
Result so far: 120996.186
Subtract 4854 from 5380 to get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Moving on to step 12:
5260 divided by 809 is 6 with a remainder of 406.
Put 6 as the next digit of the answer. 
Result so far: 120996.1866
Deduct 4854 from 5260 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Our division results in 120996.1866 with a remaining 0.00406.
