303473 ÷ 84 
We want to divide 303473 by 84.

Step 1:
When dividing 3 by 84, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 84

On to step 2:
If we divide 30 by 84, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 84

On to step 3:
If we divide 303 by 84, we get 3 and a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 252 from 303 leaves us with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 84

Advancing to step 4:
514 divided by 84 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 504 from 514 leaves us with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 84

Moving on to step 5:
When dividing 107 by 84, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 361.0
Deduct 84 from 107 and we're left with 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 84

Advancing to step 6:
84 goes into 233 2 times with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 3612.0
If we subtract 168 from 233, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
The number 84 fits into 650 7 times, leaving a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 3612.7
If we take 588 away from 650, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
84 can be fit into 620 7 times, resulting in a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 3612.77
Subtract 588 from 620 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 3612.77 with a remaining 0.032.
