We look at the division of 87212 by 81 
We want to figure out the number of times 87212 can be divided by 81.

Let's proceed to step 1:
8 divided by 81 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 81

Advancing to step 2:
When dividing 87 by 81, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 6 after subtracting 81 from 87.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 81

Step 3:
When dividing 62 by 81, we get 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 62 to get 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 81

Let's proceed to step 4:
When dividing 621 by 81, we get 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Deduct 567 from 621 and we're left with 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 81

Going ahead to step 5:
81 can be fit into 542 6 times, resulting in a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 1076.0
Deduct 486 from 542 and we're left 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.

Let's proceed to step 6:
If we divide 560 by 81, we get 6 and a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 1076.6
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
When dividing 740 by 81, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1076.69
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
The number 81 fits into 110 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1076.691
Subtract 81 from 110 to get 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 9:
When dividing 290 by 81, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 1076.6913
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.

Moving on to step 10:
If we divide 470 by 81, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 1076.69135
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.

Advancing to step 11:
If we divide 650 by 81, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1076.691358
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
The number 81 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1076.691358
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
81 goes into 200 2 times with a remainder of 38.
The next digit of our result is 2. 
Result so far: 1076.69135802
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 1076.69135802 with a remainder of 3.8e-08.
