Let's divide 931820 by 81
We're looking to find how many times 81 goes into 931820.

Advancing to step 1:
81 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 81

On to step 2:
If we divide 93 by 81, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 81 from 93 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 81

Let's proceed to step 3:
81 goes into 121 1 times with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 40 after subtracting 81 from 121.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 81

Going ahead to step 4:
When dividing 408 by 81, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
The remainder is 3 after subtracting 405 from 408.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 81

Step 5:
The number 81 fits into 32 0 times, leaving a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 1150.0
Deduct 0 from 32 and we're left with 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 81

Going ahead to step 6:
The number 81 fits into 320 3 times, leaving a remainder of 77.
The next digit of our result is 3. 
Result so far: 11503.0
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 7:
81 can be fit into 770 9 times, resulting in a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 11503.9
If we take 729 away from 770, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 8:
410 divided by 81 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 11503.95
Deduct 405 from 410 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
When dividing 50 by 81, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 11503.95
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 81, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 11503.9506
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
When dividing 140 by 81, we get 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 11503.95061
Subtract 81 from 140 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 12:
81 goes into 590 7 times with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 11503.950617
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 13:
The number 81 fits into 230 2 times, leaving a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 11503.9506172
Subtract 162 from 230 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
The number 81 fits into 680 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 11503.95061728
Subtract 648 from 680 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 11503.95061728, with a leftover of 3.2e-08.
