661733 divided by 31 
Our goal is to divide 661733 by 31.

Moving on to step 1:
When dividing 6 by 31, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
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

On to step 2:
When dividing 66 by 31, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 4 after subtracting 62 from 66.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 31

Advancing to step 3:
The number 31 fits into 41 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 10 after subtracting 31 from 41.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 31

On to step 4:
The number 31 fits into 107 3 times, leaving a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 213.0
If we subtract 93 from 107, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 31

Let's proceed to step 5:
31 goes into 143 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 2134.0
Subtract 124 from 143 to get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 31

Step 6:
The number 31 fits into 193 6 times, leaving a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 21346.0
Deduct 186 from 193 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 7:
70 divided by 31 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 21346.2
Deduct 62 from 70 and we're left 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.

Going ahead to step 8:
31 goes into 80 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 21346.22
If we take 62 away from 80, we end up 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 21346.22 with a remaining 0.018.
