We divide 307443 by 1
We want to divide 307443 by 1.

On to step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

On to step 2:
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: 30.0
If we take 0 away from 0, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Step 3:
When dividing 7 by 1, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 307.0
If we take 7 away from 7, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Moving on to step 4:
1 goes into 4 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 3074.0
If we take 4 away from 4, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Step 5:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 30744.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Advancing to step 6:
3 divided by 1 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 307443.0
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.

On to step 7:
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: 307443.0
If we subtract 0 from 0, we 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.

Step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 307443.0
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 result is 307443.0 with a remainder of 0.0.
