We're dividing 140591 by 31 
We're looking to find how many times 31 goes into 140591.

Let's proceed to step 1:
If we divide 1 by 31, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 31

Moving on to step 2:
The number 31 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 31

Let's proceed to step 3:
31 goes into 140 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 124 from 140 to get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 31

On to step 4:
The number 31 fits into 165 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 45.0
Deduct 155 from 165 and we're left with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 31

Step 5:
The number 31 fits into 109 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 453.0
Subtracting 93 from 109 leaves us with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 31

Let's proceed to step 6:
31 goes into 161 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 4535.0
If we subtract 155 from 161, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 31, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 4535.1
Subtracting 31 from 60 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 8:
31 goes into 290 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 4535.19
Deduct 279 from 290 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
The number 31 fits into 110 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 4535.193
Subtract 93 from 110 to 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.

Step 10:
170 divided by 31 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4535.1935
If we subtract 155 from 170, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
If we divide 150 by 31, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4535.19354
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
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: 4535.193548
Subtract 248 from 260 to 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 13:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 4535.1935483
If we subtract 93 from 120, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
31 goes into 270 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 4535.19354838
Deduct 248 from 270 and we're left 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.

In conclusion, the division gives 4535.19354838 with a balance of 2.2e-08.
