4199 divided by 84 
Let's see how many times 84 fits into 4199.

On to step 1:
4 divided by 84 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 84

Advancing to step 2:
41 divided by 84 is 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Grab the next digit (9) from the dividend, add it to 41, then carry on: 419 / 84

Let's proceed to step 3:
84 goes into 419 4 times with a remainder of 83.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 336 from 419 and we're left with 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 84

On to step 4:
If we divide 839 by 84, we get 9 and a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 756 from 839 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 5:
If we divide 830 by 84, we get 9 and a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.9
The remainder is 74 after subtracting 756 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 6:
740 divided by 84 is 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 49.98
If we take 672 away from 740, 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.

Going ahead to step 7:
If we divide 680 by 84, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 49.988
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.

The final result is 49.988 with a remainder of 0.0008.
