312443 divided by 1 
Let's see how many times 1 fits into 312443.

On to step 1:
If we divide 3 by 1, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

On to step 2:
1 can be fit into 1 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 1 from 1 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Going ahead to step 3:
If we divide 2 by 1, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 312.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Step 4:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 3124.0
If we subtract 4 from 4, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 5:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 31244.0
Subtract 4 from 4 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Moving on to step 6:
If we divide 3 by 1, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 312443.0
If we subtract 3 from 3, 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.

Advancing to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 312443.0
If we take 0 away from 0, 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.

Going ahead to step 8:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 312443.0
If we take 0 away from 0, 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.

After the division, we end up with 312443.0 and a remainder of 0.0.
