We look at the division of 388919 by 31 
Our goal is to divide 388919 by 31.

Step 1:
3 divided by 31 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 31

Advancing to step 2:
When dividing 38 by 31, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 7 after subtracting 31 from 38.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 31

Going ahead to step 3:
When dividing 78 by 31, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 62 away from 78, we end up with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 31

On to step 4:
31 can be fit into 169 5 times, resulting in a remainder of 14.
The next digit of our result is 5. 
Result so far: 125.0
If we take 155 away from 169, we end up with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 31

Step 5:
When dividing 141 by 31, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 1254.0
Subtract 124 from 141 to get 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 31

Moving on to step 6:
If we divide 179 by 31, we get 5 and a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 12545.0
Deduct 155 from 179 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
When dividing 240 by 31, we get 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 12545.7
Subtract 217 from 240 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
230 divided by 31 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 12545.77
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 12545.77, and the remainder is 0.013.
