Let's divide 880990 by 31
We want to divide 880990 by 31.

Moving on to step 1:
31 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 31

Advancing to step 2:
The number 31 fits into 88 2 times, leaving a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 62 from 88 and we're left with 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 31

Advancing to step 3:
260 divided by 31 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 248 from 260 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 31

On to step 4:
31 can be fit into 129 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 284.0
Subtracting 124 from 129 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 31

Let's proceed to step 5:
59 divided by 31 is 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 2841.0
The remainder is 28 after subtracting 31 from 59.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 31

Advancing to step 6:
280 divided by 31 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 28419.0
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.

Moving on to step 7:
10 divided by 31 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 28419.0
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.

Moving on to step 8:
31 goes into 100 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 28419.03
Deduct 93 from 100 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.

Let's proceed to step 9:
If we divide 70 by 31, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 28419.032
If we take 62 away from 70, we end up 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 10:
31 can be fit into 80 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 28419.0322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 28419.0322 with a remainder of 0.00018.
