We look at the division of 485779 by 31 
We want to divide 485779 by 31.

On to step 1:
31 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 31

Going ahead to step 2:
If we divide 48 by 31, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 31 from 48 leaves us with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 31

On to step 3:
The number 31 fits into 175 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 155 from 175 leaves us with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 31

Moving on to step 4:
31 can be fit into 207 6 times, resulting in a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Subtract 186 from 207 to get 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 31

Advancing to step 5:
217 divided by 31 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 1567.0
If we subtract 217 from 217, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 31

Let's proceed to step 6:
9 divided by 31 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 15670.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 15670.2
If we take 62 away from 90, we end up 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.

Let's proceed to step 8:
When dividing 280 by 31, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 15670.29
The remainder is 1 after subtracting 279 from 280.
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 9:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 15670.29
Deduct 0 from 10 and we're left with 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 10:
31 goes into 100 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 15670.2903
If we take 93 away from 100, we end up 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.

Moving on to step 11:
70 divided by 31 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 15670.29032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 15670.290322
Subtract 62 from 80 to 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.

After the division, we end up with 15670.290322 and a remainder of 1.8e-06.
