Let's divide 90420412 by 488
Our goal is to divide 90420412 by 488.

Let's proceed to step 1:
If we divide 9 by 488, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 488

Step 2:
488 goes into 90 0 times with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 488

On to step 3:
When dividing 904 by 488, we get 1 with a remainder of 416.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 488 from 904 leaves us with 416.
Include the next digit (2) from the dividend after 416, then repeat: 4162 / 488

Step 4:
4162 divided by 488 is 8 with a remainder of 258.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 3904 from 4162, we get 258.
Include the next digit (0) from the dividend after 258, then repeat: 2580 / 488

Going ahead to step 5:
The number 488 fits into 2580 5 times, leaving a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 185.0
If we take 2440 away from 2580, we end up with 140.
Take the next digit (4) from the dividend and append it to 140, then repeat: 1404 / 488

Step 6:
1404 divided by 488 is 2 with a remainder of 428.
Write down 2 as next digit of the result. 
Result so far: 1852.0
If we take 976 away from 1404, we end up with 428.
Fetch the next digit (1) from the dividend, attach it to 428 and continue: 4281 / 488

Moving on to step 7:
If we divide 4281 by 488, we get 8 and a remainder of 377.
Put 8 as the next digit of the answer. 
Result so far: 18528.0
The remainder is 377 after subtracting 3904 from 4281.
Fetch the next digit (2) from the dividend, attach it to 377 and continue: 3772 / 488

Moving on to step 8:
488 can be fit into 3772 7 times, resulting in a remainder of 356.
The number 7 becomes the next digit in our result. 
Result so far: 185287.0
If we subtract 3416 from 3772, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 9:
3560 divided by 488 is 7 with a remainder of 144.
Put 7 as the next digit of the answer. 
Result so far: 185287.7
If we subtract 3416 from 3560, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 10:
1440 divided by 488 is 2 with a remainder of 464.
The next digit of our result is 2. 
Result so far: 185287.72
The remainder is 464 after subtracting 976 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 11:
4640 divided by 488 is 9 with a remainder of 248.
Use 9 as the next digit of our solution. 
Result so far: 185287.729
Subtract 4392 from 4640 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 12:
2480 divided by 488 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 185287.7295
Subtract 2440 from 2480 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
When dividing 400 by 488, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 185287.7295
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 14:
If we divide 4000 by 488, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 185287.729508
Subtract 3904 from 4000 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
When dividing 960 by 488, we get 1 with a remainder of 472.
Record the quotient 1 as the next digit in the result. 
Result so far: 185287.7295081
Subtract 488 from 960 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 16:
If we divide 4720 by 488, we get 9 and a remainder of 328.
Put 9 as the next digit of the answer. 
Result so far: 185287.72950819
The remainder is 328 after subtracting 4392 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

In conclusion, the division gives 185287.72950819 with a balance of 3.28e-07.
