Let's divide 120804 by 82
We want to divide 120804 by 82.

Going ahead to step 1:
82 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 82

On to step 2:
82 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 82

Moving on to step 3:
82 can be fit into 120 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 82 from 120 to get 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 82

Moving on to step 4:
82 goes into 388 4 times with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 328 from 388 to get 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 82

Going ahead to step 5:
If we divide 600 by 82, we get 7 and a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Deduct 574 from 600 and we're left with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 82

On to step 6:
82 goes into 264 3 times with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 1473.0
If we subtract 246 from 264, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
The number 82 fits into 180 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 1473.2
Deduct 164 from 180 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
When dividing 160 by 82, we get 1 with a remainder of 78.
The next digit of our result is 1. 
Result so far: 1473.21
Subtract 82 from 160 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
780 divided by 82 is 9 with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 1473.219
Deduct 738 from 780 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 82, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1473.2195
Deduct 410 from 420 and we're left 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.

Advancing to step 11:
When dividing 100 by 82, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1473.21951
Deduct 82 from 100 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
82 goes into 180 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 1473.219512
Subtract 164 from 180 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 82 fits into 160 1 times, leaving a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 1473.2195121
Deduct 82 from 160 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 14:
780 divided by 82 is 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 1473.21951219
The remainder is 42 after subtracting 738 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 1473.21951219, with a leftover of 4.2e-08.
