80430 divided by 84 
We want to figure out the number of times 80430 can be divided by 84.

On to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 84

Advancing to step 2:
84 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 84

Let's proceed to step 3:
If we divide 804 by 84, we get 9 and a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 756 from 804 leaves us with 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 84

Moving on to step 4:
84 goes into 483 5 times with a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 95.0
Subtract 420 from 483 to get 63.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 84

On to step 5:
84 can be fit into 630 7 times, resulting in a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 957.0
If we take 588 away from 630, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 6:
The number 84 fits into 420 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 957.5
If we take 420 away from 420, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
84 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 957.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 84, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 957.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 957.5 and a remainder of 0.0.
