13215 divided by 83 
We want to divide 13215 by 83.

Advancing to step 1:
1 divided by 83 is 0 with 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 (3) of the dividend behind the 1 and repeat the process: 13 / 83

Advancing to step 2:
83 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 83

Advancing to step 3:
83 goes into 132 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 83 from 132 and we're left with 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 83

Advancing to step 4:
If we divide 491 by 83, we get 5 and a remainder of 76.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 415 from 491, we get 76.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 83

Advancing to step 5:
When dividing 765 by 83, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtracting 747 from 765 leaves us 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.

On to step 6:
83 goes into 180 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 159.2
If we take 166 away from 180, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
83 goes into 140 1 times with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 159.21
If we subtract 83 from 140, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 8:
When dividing 570 by 83, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 159.216
If we subtract 498 from 570, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
If we divide 720 by 83, we get 8 and a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 159.2168
Subtract 664 from 720 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
83 goes into 560 6 times with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 159.21686
If we take 498 away from 560, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
83 can be fit into 620 7 times, resulting in a remainder of 39.
The next digit of our result is 7. 
Result so far: 159.216867
If we subtract 581 from 620, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
390 divided by 83 is 4 with a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 159.2168674
Deduct 332 from 390 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 13:
When dividing 580 by 83, we get 6 with a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 159.21686746
Deduct 498 from 580 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The final outcome is 159.21686746, with a leftover of 8.2e-08.
