We're dividing 31224018 by 909 
We want to figure out the number of times 31224018 can be divided by 909.

Moving on to step 1:
The number 909 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 909

On to step 2:
If we divide 31 by 909, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 909

Advancing to step 3:
If we divide 312 by 909, we get 0 and a remainder of 312.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 312 to get 312.
Bring next digit (2) of the dividend behind the 312 and repeat the process: 3122 / 909

Step 4:
If we divide 3122 by 909, we get 3 and a remainder of 395.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 395 after subtracting 2727 from 3122.
Grab the next digit (4) from the dividend, add it to 395, then carry on: 3954 / 909

On to step 5:
When dividing 3954 by 909, we get 4 with a remainder of 318.
The next digit of our result is 4. 
Result so far: 34.0
Deduct 3636 from 3954 and we're left with 318.
Fetch the next digit (0) from the dividend, attach it to 318 and continue: 3180 / 909

Moving on to step 6:
The number 909 fits into 3180 3 times, leaving a remainder of 453.
Record the quotient 3 as the next digit in the result. 
Result so far: 343.0
Subtract 2727 from 3180 to get 453.
Grab the next digit (1) from the dividend, add it to 453, then carry on: 4531 / 909

Let's proceed to step 7:
If we divide 4531 by 909, we get 4 and a remainder of 895.
The number 4 becomes the next digit in our result. 
Result so far: 3434.0
Subtracting 3636 from 4531 leaves us with 895.
Grab the next digit (8) from the dividend, add it to 895, then carry on: 8958 / 909

Advancing to step 8:
909 can be fit into 8958 9 times, resulting in a remainder of 777.
The number 9 becomes the next digit in our result. 
Result so far: 34349.0
The remainder is 777 after subtracting 8181 from 8958.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Let's proceed to step 9:
7770 divided by 909 is 8 with a remainder of 498.
The number 8 becomes the next digit in our result. 
Result so far: 34349.8
If we subtract 7272 from 7770, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 10:
If we divide 4980 by 909, we get 5 and a remainder of 435.
Record the quotient 5 as the next digit in the result. 
Result so far: 34349.85
Subtracting 4545 from 4980 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 11:
909 goes into 4350 4 times with a remainder of 714.
Record the quotient 4 as the next digit in the result. 
Result so far: 34349.854
Subtract 3636 from 4350 to get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Let's proceed to step 12:
When dividing 7140 by 909, we get 7 with a remainder of 777.
Put 7 as the next digit of the answer. 
Result so far: 34349.8547
Subtracting 6363 from 7140 leaves us with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Let's proceed to step 13:
909 can be fit into 7770 8 times, resulting in a remainder of 498.
Put 8 as the next digit of the answer. 
Result so far: 34349.85478
If we subtract 7272 from 7770, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 14:
909 goes into 4980 5 times with a remainder of 435.
Use 5 as the next digit of our solution. 
Result so far: 34349.854785
Subtract 4545 from 4980 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 15:
4350 divided by 909 is 4 with a remainder of 714.
Put 4 as the next digit of the answer. 
Result so far: 34349.8547854
If we subtract 3636 from 4350, we get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Advancing to step 16:
909 goes into 7140 7 times with a remainder of 777.
The next digit of our result is 7. 
Result so far: 34349.85478547
Subtract 6363 from 7140 to get 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

The final result is 34349.85478547 with a remainder of 7.77e-07.
