We're dividing 286343 by 83 
We want to divide 286343 by 83.

Advancing to step 1:
When dividing 2 by 83, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 83

Going ahead to step 2:
83 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 83

Let's proceed to step 3:
83 goes into 286 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 249 from 286, we get 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 83

On to step 4:
The number 83 fits into 373 4 times, leaving a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 34.0
The remainder is 41 after subtracting 332 from 373.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 83

Advancing to step 5:
The number 83 fits into 414 4 times, leaving a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 344.0
Subtract 332 from 414 to get 82.
Append the next digit (3) from the dividend to 82 and continue with: 823 / 83

Let's proceed to step 6:
When dividing 823 by 83, we get 9 with a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 3449.0
Deduct 747 from 823 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 7:
83 goes into 760 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 3449.9
Subtract 747 from 760 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
The number 83 fits into 130 1 times, leaving a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 3449.91
If we subtract 83 from 130, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
When dividing 470 by 83, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 3449.915
If we subtract 415 from 470, 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.

Advancing to step 10:
If we divide 550 by 83, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 3449.9156
Deduct 498 from 550 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
83 goes into 520 6 times with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 3449.91566
The remainder is 22 after subtracting 498 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 3449.91566, with a leftover of 2.2e-05.
