We look at the division of 31089689 by 9 
Let's see how many times 9 fits into 31089689.

Let's proceed to step 1:
3 divided by 9 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 9

Advancing to step 2:
9 goes into 31 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 4 after subtracting 27 from 31.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 9

Going ahead to step 3:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 36 from 40 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 9

Let's proceed to step 4:
When dividing 48 by 9, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 345.0
If we take 45 away from 48, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 9

Let's proceed to step 5:
9 can be fit into 39 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 3454.0
If we subtract 36 from 39, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 9

On to step 6:
36 divided by 9 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 34544.0
Subtracting 36 from 36 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 9

Let's proceed to step 7:
When dividing 8 by 9, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 345440.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 9

Moving on to step 8:
9 goes into 89 9 times with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 3454409.0
Subtract 81 from 89 to get 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 9:
80 divided by 9 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 3454409.8
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3454409.88
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 3454409.88 and a remainder of 0.008.
