We're dividing 309031 by 1 
We want to figure out the number of times 309031 can be divided by 1.

Step 1:
3 divided by 1 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

On to step 2:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 0, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

On to step 3:
9 divided by 1 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
Deduct 9 from 9 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

On to step 4:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3090.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Step 5:
If we divide 3 by 1, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 30903.0
Subtract 3 from 3 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Advancing to step 6:
When dividing 1 by 1, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 309031.0
Deduct 1 from 1 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 309031.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 309031.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 309031.0, with a leftover of 0.0.
