Let's divide 120086 by 4
Our goal is to divide 120086 by 4.

Step 1:
If we divide 1 by 4, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 4

On to step 2:
If we divide 12 by 4, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 12 from 12, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

Step 3:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 0, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

Moving on to step 4:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 300.0
Subtract 0 from 0 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 4

Step 5:
When dividing 8 by 4, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 3002.0
Subtract 8 from 8 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 4

On to step 6:
When dividing 6 by 4, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 30021.0
The remainder is 2 after subtracting 4 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 4 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 30021.5
Subtract 20 from 20 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.

Step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 30021.5
If we take 0 away from 0, 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.

Going ahead to step 9:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30021.5
If we subtract 0 from 0, we 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.

The final result is 30021.5 with a remainder of 0.0.
