140423 ÷ 1 
We want to figure out the number of times 140423 can be divided by 1.

On to step 1:
When dividing 1 by 1, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Moving on to step 2:
If we divide 4 by 1, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Going ahead to step 3:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

On to step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 1404.0
If we subtract 4 from 4, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 5:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 14042.0
Deduct 2 from 2 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Step 6:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 140423.0
If we take 3 away from 3, we end up 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.

Advancing to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 140423.0
Subtracting 0 from 0 leaves us 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.

On to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 140423.0
Deduct 0 from 0 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.

The final result is 140423.0 with a remainder of 0.0.
