Let's divide 486812 by 31
We want to divide 486812 by 31.

Advancing to step 1:
31 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 31

On to step 2:
48 divided by 31 is 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 31 from 48 to get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 31

Going ahead to step 3:
31 goes into 176 5 times with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 155 from 176, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 31

Advancing to step 4:
If we divide 218 by 31, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 157.0
The remainder is 1 after subtracting 217 from 218.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 31

Let's proceed to step 5:
31 goes into 11 0 times with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 1570.0
Subtract 0 from 11 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 31

Step 6:
112 divided by 31 is 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 15703.0
Subtracting 93 from 112 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 31 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 15703.6
The remainder is 4 after subtracting 186 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
31 can be fit into 40 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 15703.61
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
31 goes into 90 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 15703.612
Deduct 62 from 90 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 15703.6129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
When dividing 10 by 31, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15703.6129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 31, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 15703.612903
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
31 goes into 70 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 15703.6129032
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
31 can be fit into 80 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 15703.61290322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 15703.61290322, and the remainder is 1.8e-08.
