399995 ÷ 84 
We want to figure out the number of times 399995 can be divided by 84.

Advancing to step 1:
84 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 84

Let's proceed to step 2:
When dividing 39 by 84, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 84

Step 3:
When dividing 399 by 84, we get 4 with a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 336 from 399 to get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 84

Going ahead to step 4:
84 can be fit into 639 7 times, resulting in a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 588 away from 639, we end up with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 84

Step 5:
The number 84 fits into 519 6 times, leaving a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 476.0
The remainder is 15 after subtracting 504 from 519.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 84

Moving on to step 6:
155 divided by 84 is 1 with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 4761.0
If we subtract 84 from 155, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 7:
84 goes into 710 8 times with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 4761.8
If we subtract 672 from 710, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
The number 84 fits into 380 4 times, leaving a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 4761.84
Subtracting 336 from 380 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
The number 84 fits into 440 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4761.845
If we take 420 away from 440, we end up 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.

Going ahead to step 10:
84 goes into 200 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 4761.8452
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 84, we get 3 and a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 4761.84523
Subtracting 252 from 320 leaves us 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.

Let's proceed to step 12:
The number 84 fits into 680 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 4761.845238
Deduct 672 from 680 and we're left 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.

On to step 13:
When dividing 80 by 84, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4761.845238
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.

Advancing to step 14:
800 divided by 84 is 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 4761.84523809
If we subtract 756 from 800, we 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.

The final outcome is 4761.84523809, with a leftover of 4.4e-08.
