4909 divided by 31 
We want to divide 4909 by 31.

Moving on to step 1:
31 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 31

Step 2:
31 goes into 49 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 18 after subtracting 31 from 49.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 31

On to step 3:
If we divide 180 by 31, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 155 from 180 leaves us with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 31

Going ahead to step 4:
31 goes into 259 8 times with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtract 248 from 259 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 5:
31 can be fit into 110 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 158.3
If we subtract 93 from 110, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 6:
The number 31 fits into 170 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 158.35
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
31 goes into 150 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 158.354
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.

Step 8:
If we divide 260 by 31, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 158.3548
Deduct 248 from 260 and we're left with 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 9:
31 goes into 120 3 times with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 158.35483
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.

Moving on to step 10:
The number 31 fits into 270 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 158.354838
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
If we divide 220 by 31, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 158.3548387
If we take 217 away from 220, we end up 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.

Advancing to step 12:
If we divide 30 by 31, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 158.3548387
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 158.3548387 with a remainder of 3e-08.
