121805 ÷ 82 
Let's see how many times 82 fits into 121805.

On to step 1:
82 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 82

Moving on to step 2:
When dividing 12 by 82, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 82

On to step 3:
If we divide 121 by 82, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 82 from 121 and we're left with 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 82

On to step 4:
82 goes into 398 4 times with a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 70 after subtracting 328 from 398.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 82

Advancing to step 5:
700 divided by 82 is 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 148.0
If we subtract 656 from 700, we get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 82

On to step 6:
If we divide 445 by 82, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1485.0
If we subtract 410 from 445, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
The number 82 fits into 350 4 times, leaving a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 1485.4
If we take 328 away from 350, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
When dividing 220 by 82, we get 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 1485.42
Deduct 164 from 220 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.

Advancing to step 9:
If we divide 560 by 82, we get 6 and a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 1485.426
Deduct 492 from 560 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
82 can be fit into 680 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1485.4268
Subtract 656 from 680 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
82 can be fit into 240 2 times, resulting in a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 1485.42682
The remainder is 76 after subtracting 164 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
The number 82 fits into 760 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1485.426829
If we take 738 away from 760, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
82 can be fit into 220 2 times, resulting in a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 1485.4268292
Deduct 164 from 220 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.

On to step 14:
If we divide 560 by 82, we get 6 and a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 1485.42682926
If we take 492 away from 560, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 1485.42682926, with a leftover of 6.8e-08.
