We're dividing 20306 by 57 
Let's see how many times 57 fits into 20306.

On to step 1:
The number 57 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 57

Step 2:
If we divide 20 by 57, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 57

Step 3:
The number 57 fits into 203 3 times, leaving a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 171 from 203 to get 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 57

Advancing to step 4:
The number 57 fits into 320 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 35.0
If we take 285 away from 320, we end up with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 57

Going ahead to step 5:
The number 57 fits into 356 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 356.0
Deduct 342 from 356 and we're left 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.

Advancing to step 6:
140 divided by 57 is 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 356.2
If we take 114 away from 140, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
If we divide 260 by 57, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 356.24
Subtract 228 from 260 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.

On to step 8:
When dividing 320 by 57, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 356.245
Deduct 285 from 320 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
350 divided by 57 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 356.2456
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 57, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 356.24561
If we subtract 57 from 80, we 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.

Step 11:
57 goes into 230 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 356.245614
The remainder is 2 after subtracting 228 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
57 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 356.245614
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
200 divided by 57 is 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 356.24561403
If we take 171 away from 200, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 356.24561403, and the remainder is 2.9e-08.
