159490 ÷ 31 
We want to figure out the number of times 159490 can be divided by 31.

Step 1:
31 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 31

Advancing to step 2:
15 divided by 31 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 31

Moving on to step 3:
The number 31 fits into 159 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 155 away from 159, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 31

Step 4:
44 divided by 31 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 31 from 44, we get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 31

Let's proceed to step 5:
The number 31 fits into 139 4 times, leaving a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 514.0
Subtract 124 from 139 to get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 31

Going ahead to step 6:
31 goes into 150 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 5144.0
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
31 can be fit into 260 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 5144.8
If we subtract 248 from 260, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
31 can be fit into 120 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 5144.83
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
31 goes into 270 8 times with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 5144.838
If we take 248 away from 270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
If we divide 220 by 31, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 5144.8387
Deduct 217 from 220 and we're left 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.

On to step 11:
When dividing 30 by 31, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 5144.8387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
The number 31 fits into 300 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 5144.838709
If we take 279 away from 300, we end up 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.

Step 13:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 5144.8387096
Subtract 186 from 210 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
If we divide 240 by 31, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 5144.83870967
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 5144.83870967 and a remainder of 2.3e-08.
