We look at the division of 81209598 by 81 
Let's see how many times 81 fits into 81209598.

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

Moving on to step 2:
81 goes into 81 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 81 from 81 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 81

Let's proceed to step 3:
81 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 81

Let's proceed to step 4:
The number 81 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 81

Let's proceed to step 5:
81 can be fit into 209 2 times, resulting in a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 1002.0
Subtracting 162 from 209 leaves us with 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 81

Going ahead to step 6:
If we divide 475 by 81, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 10025.0
Deduct 405 from 475 and we're left with 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 81

Let's proceed to step 7:
When dividing 709 by 81, we get 8 with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 100258.0
Subtract 648 from 709 to get 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 81

Moving on to step 8:
When dividing 618 by 81, we get 7 with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 1002587.0
The remainder is 51 after subtracting 567 from 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
The number 81 fits into 510 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 1002587.6
Subtract 486 from 510 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
If we divide 240 by 81, we get 2 and a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 1002587.62
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
When dividing 780 by 81, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 1002587.629
If we take 729 away from 780, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 12:
When dividing 510 by 81, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1002587.6296
Deduct 486 from 510 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
When dividing 240 by 81, we get 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 1002587.62962
If we take 162 away from 240, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 14:
The number 81 fits into 780 9 times, leaving a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 1002587.629629
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 15:
When dividing 510 by 81, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 1002587.6296296
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 16:
81 goes into 240 2 times with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 1002587.62962962
Deduct 162 from 240 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The quotient of the division is 1002587.62962962, and the remainder is 7.8e-08.
