We divide 406399 by 84
Let's see how many times 84 fits into 406399.

Let's proceed to step 1:
When dividing 4 by 84, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 84

Advancing to step 2:
The number 84 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 84

Moving on to step 3:
84 goes into 406 4 times with a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 336 from 406 and we're left with 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 84

Moving on to step 4:
When dividing 703 by 84, we get 8 with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 31 after subtracting 672 from 703.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 84

Going ahead to step 5:
319 divided by 84 is 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 483.0
Deduct 252 from 319 and we're left with 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 84

On to step 6:
If we divide 679 by 84, we get 8 and a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 4838.0
Subtracting 672 from 679 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 84, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4838.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
If we divide 700 by 84, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 4838.08
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.

Step 9:
84 goes into 280 3 times with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 4838.083
Subtracting 252 from 280 leaves us 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.

Let's proceed to step 10:
84 can be fit into 280 3 times, resulting in a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 4838.0833
If we subtract 252 from 280, we 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 4838.0833 with a remaining 0.00028.
