Let's divide 648912 by 31
Let's see how many times 31 fits into 648912.

Let's proceed to step 1:
The number 31 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 31

Moving on to step 2:
31 can be fit into 64 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 62 from 64 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 31

On to step 3:
The number 31 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 28, we get 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 31

Moving on to step 4:
When dividing 289 by 31, we get 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 209.0
Deduct 279 from 289 and we're left with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 31

Moving on to step 5:
If we divide 101 by 31, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 2093.0
If we take 93 away from 101, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 31

Going ahead to step 6:
When dividing 82 by 31, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 20932.0
If we take 62 away from 82, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
When dividing 200 by 31, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 20932.6
If we subtract 186 from 200, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
31 goes into 140 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 20932.64
The remainder is 16 after subtracting 124 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 20932.645
If we take 155 away from 160, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
31 goes into 50 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 20932.6451
If we take 31 away from 50, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
If we divide 190 by 31, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 20932.64516
The remainder is 4 after subtracting 186 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
31 goes into 40 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 20932.645161
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
The number 31 fits into 90 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 20932.6451612
The remainder is 28 after subtracting 62 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 20932.64516129
Subtract 279 from 280 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 20932.64516129 with a remaining 1e-09.
