661189 divided by 31 
We're looking to find how many times 31 goes into 661189.

Step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 31

Step 2:
When dividing 66 by 31, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 62 from 66 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 31

Let's proceed to step 3:
If we divide 41 by 31, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 31 from 41 to get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 31

Step 4:
When dividing 101 by 31, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 213.0
Subtracting 93 from 101 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 31

Going ahead to step 5:
If we divide 88 by 31, we get 2 and a remainder of 26.
The next digit of our result is 2. 
Result so far: 2132.0
Deduct 62 from 88 and we're left with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 31

Going ahead to step 6:
If we divide 269 by 31, we get 8 and a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 21328.0
Subtract 248 from 269 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 31, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 21328.6
Deduct 186 from 210 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.

Going ahead to step 8:
When dividing 240 by 31, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 21328.67
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
230 divided by 31 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 21328.677
If we take 217 away from 230, we end up with 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 final outcome is 21328.677, with a leftover of 0.0013.
