Let's divide 15386863 by 492
We want to divide 15386863 by 492.

Advancing to step 1:
492 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 492

Going ahead to step 2:
492 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 492

On to step 3:
492 can be fit into 153 0 times, resulting in a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 153, we get 153.
Append the next digit (8) from the dividend to 153 and continue with: 1538 / 492

On to step 4:
The number 492 fits into 1538 3 times, leaving a remainder of 62.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 62 after subtracting 1476 from 1538.
Fetch the next digit (6) from the dividend, attach it to 62 and continue: 626 / 492

On to step 5:
If we divide 626 by 492, we get 1 and a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 492 from 626 to get 134.
Include the next digit (8) from the dividend after 134, then repeat: 1348 / 492

On to step 6:
If we divide 1348 by 492, we get 2 and a remainder of 364.
Use 2 as the next digit of our solution. 
Result so far: 312.0
Subtracting 984 from 1348 leaves us with 364.
Append the next digit (6) from the dividend to 364 and continue with: 3646 / 492

Advancing to step 7:
When dividing 3646 by 492, we get 7 with a remainder of 202.
Record the quotient 7 as the next digit in the result. 
Result so far: 3127.0
Subtract 3444 from 3646 to get 202.
Take the next digit (3) from the dividend and append it to 202, then repeat: 2023 / 492

Advancing to step 8:
492 goes into 2023 4 times with a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 31274.0
If we subtract 1968 from 2023, 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.

Moving on to step 9:
492 can be fit into 550 1 times, resulting in a remainder of 58.
The next digit of our result is 1. 
Result so far: 31274.1
The remainder is 58 after subtracting 492 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
The number 492 fits into 580 1 times, leaving a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 31274.11
The remainder is 88 after subtracting 492 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 31274.11 and a remainder of 0.088.
