86303 ÷ 57 
We're looking to find how many times 57 goes into 86303.

On to step 1:
57 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 57

Let's proceed to step 2:
The number 57 fits into 86 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 57 from 86, we get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 57

Moving on to step 3:
57 can be fit into 293 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 8 after subtracting 285 from 293.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 57

Step 4:
57 goes into 80 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 151.0
The remainder is 23 after subtracting 57 from 80.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 57

Going ahead to step 5:
57 can be fit into 233 4 times, resulting in a remainder of 5.
The next digit of our result is 4. 
Result so far: 1514.0
The remainder is 5 after subtracting 228 from 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
When dividing 50 by 57, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1514.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
When dividing 500 by 57, we get 8 with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 1514.08
If we take 456 away from 500, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
When dividing 440 by 57, we get 7 with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 1514.087
Subtracting 399 from 440 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
57 can be fit into 410 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 1514.0877
Deduct 399 from 410 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 1514.0877 with a remainder of 0.00011.
