339093 ÷ 31 
We want to figure out the number of times 339093 can be divided by 31.

Moving on to step 1:
31 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 31

Let's proceed to step 2:
31 can be fit into 33 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 31 from 33 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 31

Advancing to step 3:
29 divided by 31 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 29 to get 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 31

Step 4:
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: 109.0
Subtracting 279 from 290 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 31

Going ahead to step 5:
The number 31 fits into 119 3 times, leaving a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 1093.0
Subtract 93 from 119 to get 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 31

On to step 6:
When dividing 263 by 31, we get 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 10938.0
The remainder is 15 after subtracting 248 from 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 31, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 10938.4
Subtracting 124 from 150 leaves us 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 next digit of our result is 8. 
Result so far: 10938.48
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.

Step 9:
The number 31 fits into 120 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 10938.483
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.

On to step 10:
If we divide 270 by 31, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 10938.4838
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.

Going ahead to step 11:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 10938.48387
Subtract 217 from 220 to get 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 12:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10938.48387
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.

On to step 13:
When dividing 300 by 31, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 10938.4838709
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 14:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 10938.48387096
If we subtract 186 from 210, we 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.

After the division, we end up with 10938.48387096 and a remainder of 2.4e-08.
