We divide 81885516 by 809
We want to figure out the number of times 81885516 can be divided by 809.

Let's proceed to step 1:
809 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 809

On to step 2:
809 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 809

On to step 3:
If we divide 818 by 809, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 809 from 818, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 809

On to step 4:
The number 809 fits into 98 0 times, leaving a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 98, we get 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 809

On to step 5:
809 can be fit into 985 1 times, resulting in a remainder of 176.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 809 from 985 and we're left with 176.
Take the next digit (5) from the dividend and append it to 176, then repeat: 1765 / 809

Let's proceed to step 6:
When dividing 1765 by 809, we get 2 with a remainder of 147.
The next digit of our result is 2. 
Result so far: 1012.0
Subtracting 1618 from 1765 leaves us with 147.
Append the next digit (1) from the dividend to 147 and continue with: 1471 / 809

Going ahead to step 7:
When dividing 1471 by 809, we get 1 with a remainder of 662.
Write down 1 as next digit of the result. 
Result so far: 10121.0
Deduct 809 from 1471 and we're left with 662.
Fetch the next digit (6) from the dividend, attach it to 662 and continue: 6626 / 809

On to step 8:
809 can be fit into 6626 8 times, resulting in a remainder of 154.
Put 8 as the next digit of the answer. 
Result so far: 101218.0
Subtracting 6472 from 6626 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 9:
809 can be fit into 1540 1 times, resulting in a remainder of 731.
The number 1 becomes the next digit in our result. 
Result so far: 101218.1
Subtract 809 from 1540 to get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Let's proceed to step 10:
When dividing 7310 by 809, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 101218.19
If we take 7281 away from 7310, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
If we divide 290 by 809, we get 0 and a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 101218.19
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 12:
When dividing 2900 by 809, we get 3 with a remainder of 473.
The number 3 becomes the next digit in our result. 
Result so far: 101218.1903
If we subtract 2427 from 2900, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 13:
If we divide 4730 by 809, we get 5 and a remainder of 685.
Record the quotient 5 as the next digit in the result. 
Result so far: 101218.19035
If we take 4045 away from 4730, we end up with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Moving on to step 14:
809 goes into 6850 8 times with a remainder of 378.
The number 8 becomes the next digit in our result. 
Result so far: 101218.190358
If we subtract 6472 from 6850, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 15:
If we divide 3780 by 809, we get 4 and a remainder of 544.
The next digit of our result is 4. 
Result so far: 101218.1903584
The remainder is 544 after subtracting 3236 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 16:
The number 809 fits into 5440 6 times, leaving a remainder of 586.
Write down 6 as next digit of the result. 
Result so far: 101218.19035846
Subtracting 4854 from 5440 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

After the division, we end up with 101218.19035846 and a remainder of 5.86e-07.
