We're dividing 443886 by 31 
Let's see how many times 31 fits into 443886.

Moving on to step 1:
If we divide 4 by 31, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 31

Moving on to step 2:
44 divided by 31 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 31 from 44 leaves us with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 31

Step 3:
If we divide 133 by 31, we get 4 and a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 124 from 133 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 31

Moving on to step 4:
98 divided by 31 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 143.0
Subtract 93 from 98 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 31

Moving on to step 5:
58 divided by 31 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1431.0
If we subtract 31 from 58, we get 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 31

On to step 6:
When dividing 276 by 31, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 14318.0
Deduct 248 from 276 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 14318.9
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
When dividing 10 by 31, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 14318.9
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
The number 31 fits into 100 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 14318.903
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
31 goes into 70 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 14318.9032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 31, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 14318.90322
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 14318.90322 with a remainder of 1.8e-05.
