We're dividing 945457 by 3 
Let's see how many times 3 fits into 945457.

Let's proceed to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 9 from 9 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Step 2:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 3 from 4, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

Advancing to step 3:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 315.0
Subtract 15 from 15 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

On to step 4:
3 goes into 4 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 3151.0
If we subtract 3 from 4, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Advancing to step 5:
15 divided by 3 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 31515.0
Subtracting 15 from 15 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Going ahead to step 6:
7 divided by 3 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 315152.0
Deduct 6 from 7 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 315152.3
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 315152.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 315152.33 and a remainder of 0.001.
