394904 ÷ 84 
We want to figure out the number of times 394904 can be divided by 84.

Step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 84

Moving on to step 2:
84 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 84

Advancing to step 3:
84 can be fit into 394 4 times, resulting in a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 336 away from 394, we end up with 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 84

Step 4:
When dividing 589 by 84, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 47.0
Subtract 588 from 589 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 84

Step 5:
The number 84 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 470.0
If we subtract 0 from 10, we get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 84

Moving on to step 6:
If we divide 104 by 84, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 4701.0
Deduct 84 from 104 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 4701.2
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
The number 84 fits into 320 3 times, leaving a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 4701.23
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
84 goes into 680 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 4701.238
If we take 672 away from 680, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4701.238
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 4701.23809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
When dividing 440 by 84, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 4701.238095
Deduct 420 from 440 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 4701.2380952
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
320 divided by 84 is 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 4701.23809523
Deduct 252 from 320 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 4701.23809523 with a balance of 6.8e-08.
