We look at the division of 486703 by 31 
Our goal is to divide 486703 by 31.

Advancing to step 1:
If we divide 4 by 31, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 31

Let's proceed to step 2:
If we divide 48 by 31, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 31 from 48 and we're left with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 31

Advancing to step 3:
31 can be fit into 176 5 times, resulting in a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 155 from 176 and we're left with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 31

Moving on to step 4:
If we divide 217 by 31, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 157.0
Subtract 217 from 217 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 31

Let's proceed to step 5:
31 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1570.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 31

Moving on to step 6:
31 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 15700.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
31 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 15700.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 31, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 15700.09
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
31 can be fit into 210 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 15700.096
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
If we divide 240 by 31, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 15700.0967
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 11:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 15700.09677
Subtracting 217 from 230 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 15700.09677 and a remainder of 1.3e-05.
