9609403 divided by 31 
Our goal is to divide 9609403 by 31.

On to step 1:
9 divided by 31 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 31

On to step 2:
When dividing 96 by 31, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 93 from 96 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 31

Let's proceed to step 3:
When dividing 30 by 31, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 31

Step 4:
When dividing 309 by 31, we get 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 309.0
Subtracting 279 from 309 leaves us with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 31

Going ahead to step 5:
304 divided by 31 is 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 3099.0
The remainder is 25 after subtracting 279 from 304.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 31

On to step 6:
250 divided by 31 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 30998.0
If we subtract 248 from 250, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 31

Moving on to step 7:
The number 31 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 309980.0
Subtracting 0 from 23 leaves us 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 8:
If we divide 230 by 31, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 309980.7
If we subtract 217 from 230, we 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.

Step 9:
31 can be fit into 130 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 309980.74
The remainder is 6 after subtracting 124 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
31 goes into 60 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 309980.741
If we take 31 away from 60, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 11:
When dividing 290 by 31, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 309980.7419
If we subtract 279 from 290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
110 divided by 31 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 309980.74193
Subtracting 93 from 110 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
170 divided by 31 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 309980.741935
Subtracting 155 from 170 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
31 can be fit into 150 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 309980.7419354
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 15:
When dividing 260 by 31, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 309980.74193548
Subtract 248 from 260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 309980.74193548 with a remainder of 1.2e-08.
