Let's divide 971812 by 81
Let's see how many times 81 fits into 971812.

Advancing to step 1:
The number 81 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 81

On to step 2:
97 divided by 81 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 81 from 97 and we're left with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 81

Let's proceed to step 3:
The number 81 fits into 161 1 times, leaving a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 81 from 161 to get 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 81

Step 4:
When dividing 808 by 81, we get 9 with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we take 729 away from 808, we end up with 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 81

On to step 5:
If we divide 791 by 81, we get 9 and a remainder of 62.
The next digit of our result is 9. 
Result so far: 1199.0
If we subtract 729 from 791, we get 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 81

Step 6:
622 divided by 81 is 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 11997.0
If we subtract 567 from 622, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 7:
550 divided by 81 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 11997.6
The remainder is 64 after subtracting 486 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
The number 81 fits into 640 7 times, leaving a remainder of 73.
The next digit of our result is 7. 
Result so far: 11997.67
If we subtract 567 from 640, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
81 goes into 730 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 11997.679
Deduct 729 from 730 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
81 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 11997.679
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
When dividing 100 by 81, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11997.67901
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
81 goes into 190 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 11997.679012
Deduct 162 from 190 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
81 goes into 280 3 times with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 11997.6790123
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
370 divided by 81 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 11997.67901234
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 11997.67901234, with a leftover of 4.6e-08.
