439642 ÷ 84 
We're looking to find how many times 84 goes into 439642.

Going ahead to step 1:
4 divided by 84 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 84

Moving on to step 2:
84 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 84

Advancing to step 3:
439 divided by 84 is 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 19 after subtracting 420 from 439.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 84

Going ahead to step 4:
When dividing 196 by 84, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 52.0
Deduct 168 from 196 and we're left with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 84

Step 5:
84 goes into 284 3 times with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 523.0
Subtract 252 from 284 to get 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 84

On to step 6:
322 divided by 84 is 3 with a remainder of 70.
The next digit of our result is 3. 
Result so far: 5233.0
If we subtract 252 from 322, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
When dividing 700 by 84, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 5233.8
If we take 672 away from 700, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
If we divide 280 by 84, we get 3 and a remainder of 28.
The next digit of our result is 3. 
Result so far: 5233.83
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
84 goes into 280 3 times with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 5233.833
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 5233.833 with a remaining 0.0028.
