We divide 712487 by 81
We want to figure out the number of times 712487 can be divided by 81.

Advancing to step 1:
81 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 81

Moving on to step 2:
When dividing 71 by 81, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 81

On to step 3:
81 goes into 712 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 648 from 712 to get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 81

On to step 4:
81 goes into 644 7 times with a remainder of 77.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 567 from 644 to get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 81

Let's proceed to step 5:
778 divided by 81 is 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 879.0
Deduct 729 from 778 and we're left with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 81

Let's proceed to step 6:
81 can be fit into 497 6 times, resulting in a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 8796.0
The remainder is 11 after subtracting 486 from 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
81 goes into 110 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 8796.1
The remainder is 29 after subtracting 81 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
When dividing 290 by 81, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 8796.13
Deduct 243 from 290 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
81 can be fit into 470 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 8796.135
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
When dividing 650 by 81, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8796.1358
If we subtract 648 from 650, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
81 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8796.1358
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 8796.135802
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
If we divide 380 by 81, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 8796.1358024
Subtracting 324 from 380 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
81 goes into 560 6 times with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 8796.13580246
Subtracting 486 from 560 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 8796.13580246 and a remainder of 7.4e-08.
