446317 ÷ 31 
Our goal is to divide 446317 by 31.

On to step 1:
4 divided by 31 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 31

Step 2:
44 divided by 31 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 13 after subtracting 31 from 44.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 31

Step 3:
If we divide 136 by 31, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 14.0
If we take 124 away from 136, we end up with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 31

Step 4:
31 goes into 123 3 times with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
The remainder is 30 after subtracting 93 from 123.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 31

On to step 5:
When dividing 301 by 31, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 1439.0
Subtract 279 from 301 to get 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 31

Going ahead to step 6:
The number 31 fits into 227 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 14397.0
If we take 217 away from 227, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
31 goes into 100 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 14397.3
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
70 divided by 31 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 14397.32
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
31 goes into 80 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 14397.322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 14397.322 and a remainder of 0.0018.
