81098081 divided by 809 
Let's see how many times 809 fits into 81098081.

Let's proceed to step 1:
8 divided by 809 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 809

Advancing to step 2:
81 divided by 809 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 809

On to step 3:
The number 809 fits into 810 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 809 from 810, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 809

Moving on to step 4:
If we divide 19 by 809, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 19, we get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 809

Moving on to step 5:
If we divide 198 by 809, we get 0 and a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 198 and we're left with 198.
Bring next digit (0) of the dividend behind the 198 and repeat the process: 1980 / 809

On to step 6:
809 can be fit into 1980 2 times, resulting in a remainder of 362.
Write down 2 as next digit of the result. 
Result so far: 1002.0
The remainder is 362 after subtracting 1618 from 1980.
Take the next digit (8) from the dividend and append it to 362, then repeat: 3628 / 809

Step 7:
3628 divided by 809 is 4 with a remainder of 392.
The number 4 becomes the next digit in our result. 
Result so far: 10024.0
The remainder is 392 after subtracting 3236 from 3628.
Bring next digit (1) of the dividend behind the 392 and repeat the process: 3921 / 809

Moving on to step 8:
809 goes into 3921 4 times with a remainder of 685.
Record the quotient 4 as the next digit in the result. 
Result so far: 100244.0
If we take 3236 away from 3921, 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.

Going ahead to step 9:
6850 divided by 809 is 8 with a remainder of 378.
Record the quotient 8 as the next digit in the result. 
Result so far: 100244.8
The remainder is 378 after subtracting 6472 from 6850.
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 10:
809 goes into 3780 4 times with a remainder of 544.
The number 4 becomes the next digit in our result. 
Result so far: 100244.84
Subtracting 3236 from 3780 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 11:
The number 809 fits into 5440 6 times, leaving a remainder of 586.
Put 6 as the next digit of the answer. 
Result so far: 100244.846
If we take 4854 away from 5440, we end up 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.

Advancing to step 12:
5860 divided by 809 is 7 with a remainder of 197.
Put 7 as the next digit of the answer. 
Result so far: 100244.8467
Subtracting 5663 from 5860 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 13:
809 goes into 1970 2 times with a remainder of 352.
Write down 2 as next digit of the result. 
Result so far: 100244.84672
If we take 1618 away from 1970, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 14:
If we divide 3520 by 809, we get 4 and a remainder of 284.
The next digit of our result is 4. 
Result so far: 100244.846724
If we take 3236 away from 3520, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 15:
When dividing 2840 by 809, we get 3 with a remainder of 413.
The number 3 becomes the next digit in our result. 
Result so far: 100244.8467243
The remainder is 413 after subtracting 2427 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Step 16:
If we divide 4130 by 809, we get 5 and a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 100244.84672435
Subtracting 4045 from 4130 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 100244.84672435 with a remainder of 8.5e-08.
