660161 ÷ 31 
We're looking to find how many times 31 goes into 660161.

Moving on to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 31

Moving on to step 2:
66 divided by 31 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 62 from 66 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 31

Advancing to step 3:
40 divided by 31 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 31 from 40 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 31

Advancing to step 4:
If we divide 91 by 31, we get 2 and a remainder of 29.
The next digit of our result is 2. 
Result so far: 212.0
If we subtract 62 from 91, we get 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 31

Moving on to step 5:
When dividing 296 by 31, we get 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 2129.0
If we take 279 away from 296, we end up with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 31

Step 6:
The number 31 fits into 171 5 times, leaving a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 21295.0
If we subtract 155 from 171, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
If we divide 160 by 31, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 21295.5
If we subtract 155 from 160, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
31 can be fit into 50 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 21295.51
The remainder is 19 after subtracting 31 from 50.
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 9:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 21295.516
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 31 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 21295.5161
Subtract 31 from 40 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
90 divided by 31 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 21295.51612
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 12:
280 divided by 31 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 21295.516129
If we take 279 away from 280, we end up 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 13:
31 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21295.516129
Deduct 0 from 10 and we're left 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.

On to step 14:
If we divide 100 by 31, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 21295.51612903
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 21295.51612903 with a remaining 7e-09.
