We're dividing 443623 by 84 
We're looking to find how many times 84 goes into 443623.

Going ahead to step 1:
84 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 84

Step 2:
When dividing 44 by 84, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 84

Moving on to step 3:
If we divide 443 by 84, we get 5 and a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 420 from 443 to get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 84

Going ahead to step 4:
84 can be fit into 236 2 times, resulting in a remainder of 68.
The next digit of our result is 2. 
Result so far: 52.0
Subtract 168 from 236 to get 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 84

On to step 5:
84 goes into 682 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 528.0
Subtracting 672 from 682 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 84

Moving on to step 6:
If we divide 103 by 84, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 5281.0
Deduct 84 from 103 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
The number 84 fits into 190 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 5281.2
Deduct 168 from 190 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
220 divided by 84 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 5281.22
Subtracting 168 from 220 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 5281.22 and a remainder of 0.052.
