902670 ÷ 31 
We want to divide 902670 by 31.

Step 1:
If we divide 9 by 31, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 31

Let's proceed to step 2:
90 divided by 31 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 62 from 90 to get 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 31

Going ahead to step 3:
If we divide 282 by 31, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 279 from 282 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 31

Let's proceed to step 4:
When dividing 36 by 31, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 291.0
Subtracting 31 from 36 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 31

Moving on to step 5:
31 goes into 57 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 2911.0
The remainder is 26 after subtracting 31 from 57.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 31

Step 6:
260 divided by 31 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 29118.0
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 31 is 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 29118.3
If we subtract 93 from 120, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
31 goes into 270 8 times with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 29118.38
Deduct 248 from 270 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
220 divided by 31 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 29118.387
Subtract 217 from 220 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
31 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 29118.387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
The number 31 fits into 300 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 29118.38709
Subtracting 279 from 300 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
31 goes into 210 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 29118.387096
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.

Advancing to step 13:
31 goes into 240 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 29118.3870967
If we take 217 away from 240, we end up 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.

Moving on to step 14:
If we divide 230 by 31, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 29118.38709677
Subtracting 217 from 230 leaves us 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.

After the division, we end up with 29118.38709677 and a remainder of 1.3e-08.
