661363 ÷ 31 
Our goal is to divide 661363 by 31.

Going ahead to step 1:
31 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 31

Going ahead to step 2:
31 can be fit into 66 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 62 from 66, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 31

Step 3:
31 goes into 41 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 31 from 41 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 31

Let's proceed to step 4:
The number 31 fits into 103 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 213.0
If we take 93 away from 103, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 31

Going ahead to step 5:
The number 31 fits into 106 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 2133.0
Subtracting 93 from 106 leaves us with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 31

Going ahead to step 6:
The number 31 fits into 133 4 times, leaving a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 21334.0
The remainder is 9 after subtracting 124 from 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
When dividing 90 by 31, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 21334.2
Subtract 62 from 90 to get 28.
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 8:
31 can be fit into 280 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 21334.29
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
If we divide 10 by 31, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21334.29
If we subtract 0 from 10, we 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.

Going ahead to step 10:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 21334.2903
If we take 93 away from 100, we end up 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.

Step 11:
70 divided by 31 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 21334.29032
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.

On to step 12:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 21334.290322
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.

Our division results in 21334.290322 with a remaining 1.8e-06.
