We divide 800413 by 81
We want to figure out the number of times 800413 can be divided by 81.

Let's proceed to step 1:
8 divided by 81 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 81

On to step 2:
If we divide 80 by 81, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (0) from the dividend, attach it to 80 and continue: 800 / 81

Step 3:
When dividing 800 by 81, we get 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 729 from 800 leaves us with 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 81

Moving on to step 4:
81 can be fit into 714 8 times, resulting in a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
The remainder is 66 after subtracting 648 from 714.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 81

Let's proceed to step 5:
If we divide 661 by 81, we get 8 and a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 988.0
Deduct 648 from 661 and we're left with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 81

On to step 6:
133 divided by 81 is 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 9881.0
Subtract 81 from 133 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
The number 81 fits into 520 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 9881.6
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
81 goes into 340 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 9881.64
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
81 goes into 160 1 times with a remainder of 79.
The next digit of our result is 1. 
Result so far: 9881.641
If we take 81 away from 160, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 10:
The number 81 fits into 790 9 times, leaving a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 9881.6419
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
610 divided by 81 is 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 9881.64197
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 12:
The number 81 fits into 430 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9881.641975
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
The number 81 fits into 250 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 9881.6419753
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
81 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 9881.6419753
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 9881.6419753 and a remainder of 7e-08.
