20457983 divided by 488 
We're looking to find how many times 488 goes into 20457983.

On to step 1:
488 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 488

Going ahead to step 2:
The number 488 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 488

Advancing to step 3:
488 can be fit into 204 0 times, resulting in a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 204 after subtracting 0 from 204.
Take the next digit (5) from the dividend and append it to 204, then repeat: 2045 / 488

Moving on to step 4:
2045 divided by 488 is 4 with a remainder of 93.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1952 from 2045 to get 93.
Bring next digit (7) of the dividend behind the 93 and repeat the process: 937 / 488

Moving on to step 5:
When dividing 937 by 488, we get 1 with a remainder of 449.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 488 away from 937, we end up with 449.
Fetch the next digit (9) from the dividend, attach it to 449 and continue: 4499 / 488

Going ahead to step 6:
488 goes into 4499 9 times with a remainder of 107.
Use 9 as the next digit of our solution. 
Result so far: 419.0
Subtract 4392 from 4499 to get 107.
Fetch the next digit (8) from the dividend, attach it to 107 and continue: 1078 / 488

Let's proceed to step 7:
488 goes into 1078 2 times with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 4192.0
Subtracting 976 from 1078 leaves us with 102.
Grab the next digit (3) from the dividend, add it to 102, then carry on: 1023 / 488

On to step 8:
1023 divided by 488 is 2 with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 41922.0
The remainder is 47 after subtracting 976 from 1023.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 9:
488 goes into 470 0 times with a remainder of 470.
The next digit of our result is 0. 
Result so far: 41922.0
Subtracting 0 from 470 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 10:
488 can be fit into 4700 9 times, resulting in a remainder of 308.
Put 9 as the next digit of the answer. 
Result so far: 41922.09
If we subtract 4392 from 4700, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 11:
If we divide 3080 by 488, we get 6 and a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 41922.096
Subtract 2928 from 3080 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
If we divide 1520 by 488, we get 3 and a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 41922.0963
Subtracting 1464 from 1520 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
488 goes into 560 1 times with a remainder of 72.
The next digit of our result is 1. 
Result so far: 41922.09631
Subtract 488 from 560 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
The number 488 fits into 720 1 times, leaving a remainder of 232.
Record the quotient 1 as the next digit in the result. 
Result so far: 41922.096311
Subtracting 488 from 720 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

In conclusion, the division gives 41922.096311 with a balance of 2.32e-05.
