Let's divide 9489 by 84
We're looking to find how many times 84 goes into 9489.

Going ahead to step 1:
If we divide 9 by 84, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 84

Step 2:
When dividing 94 by 84, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 84 away from 94, we end up with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 84

Step 3:
84 can be fit into 108 1 times, resulting in a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 84 from 108 leaves us with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 84

Moving on to step 4:
When dividing 249 by 84, we get 2 with a remainder of 81.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Deduct 168 from 249 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 5:
The number 84 fits into 810 9 times, leaving a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 112.9
Deduct 756 from 810 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 6:
If we divide 540 by 84, we get 6 and a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 112.96
Subtracting 504 from 540 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
If we divide 360 by 84, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 112.964
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
When dividing 240 by 84, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 112.9642
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
84 goes into 720 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 112.96428
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
480 divided by 84 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 112.964285
If we subtract 420 from 480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 112.9642857
If we take 588 away from 600, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The next digit of our result is 1. 
Result so far: 112.96428571
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 112.96428571 with a balance of 3.6e-08.
