386382 ÷ 31 
We want to divide 386382 by 31.

Going ahead to step 1:
The number 31 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 31

Let's proceed to step 2:
When dividing 38 by 31, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 31 from 38, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 31

Advancing to step 3:
31 goes into 76 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 62 from 76 to get 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 31

Let's proceed to step 4:
143 divided by 31 is 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 124.0
If we subtract 124 from 143, we get 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 31

Moving on to step 5:
When dividing 198 by 31, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 1246.0
The remainder is 12 after subtracting 186 from 198.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 31

Step 6:
The number 31 fits into 122 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 12463.0
If we subtract 93 from 122, we get 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 7:
If we divide 290 by 31, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 12463.9
Subtracting 279 from 290 leaves us 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.

Advancing to step 8:
If we divide 110 by 31, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 12463.93
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.

Let's proceed to step 9:
170 divided by 31 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 12463.935
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 10:
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: 12463.9354
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
The number 31 fits into 260 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 12463.93548
If we take 248 away from 260, we end up 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.

Moving on to step 12:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 12463.935483
Deduct 93 from 120 and we're left 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 13:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 12463.9354838
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.

Step 14:
When dividing 220 by 31, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 12463.93548387
If we subtract 217 from 220, we 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.

After the division, we end up with 12463.93548387 and a remainder of 3e-09.
