489608 ÷ 31 
We want to figure out the number of times 489608 can be divided 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
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 31

Advancing to step 2:
31 goes into 48 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 31 from 48, we get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 31

Step 3:
31 can be fit into 179 5 times, resulting in a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 155 from 179 leaves us with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 31

Moving on to step 4:
246 divided by 31 is 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 157.0
Deduct 217 from 246 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 31

Step 5:
31 can be fit into 290 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1579.0
Subtract 279 from 290 to get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 31

Moving on to step 6:
31 can be fit into 118 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 15793.0
If we take 93 away from 118, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
The number 31 fits into 250 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 15793.8
Subtracting 248 from 250 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
If we divide 20 by 31, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 15793.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 31, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 15793.806
Subtracting 186 from 200 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 15793.8064
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 15793.80645
If we take 155 away from 160, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
The number 31 fits into 50 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 15793.806451
Subtracting 31 from 50 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.

Advancing to step 13:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 15793.8064516
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 15793.80645161
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 15793.80645161, with a leftover of 9e-09.
