We're dividing 900943 by 31 
We want to divide 900943 by 31.

Step 1:
9 divided by 31 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 31

Advancing to step 2:
The number 31 fits into 90 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 62 from 90 leaves us with 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 31

Advancing to step 3:
If we divide 280 by 31, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 279 from 280 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 31

Going ahead to step 4:
When dividing 19 by 31, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 31

Let's proceed to step 5:
31 can be fit into 194 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 2906.0
Subtract 186 from 194 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 31

Moving on to step 6:
31 goes into 83 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 29062.0
If we subtract 62 from 83, we 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:
If we divide 210 by 31, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 29062.6
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.

On to step 8:
31 can be fit into 240 7 times, resulting in a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 29062.67
Deduct 217 from 240 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
When dividing 230 by 31, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 29062.677
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 29062.677 and a remainder of 0.0013.
