We divide 20448920 by 485
We want to divide 20448920 by 485.

Advancing to step 1:
If we divide 2 by 485, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 485

Step 2:
When dividing 20 by 485, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 485

Going ahead to step 3:
The number 485 fits into 204 0 times, leaving a remainder of 204.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 204, we end up with 204.
Fetch the next digit (4) from the dividend, attach it to 204 and continue: 2044 / 485

On to step 4:
If we divide 2044 by 485, we get 4 and a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1940 from 2044 and we're left with 104.
Append the next digit (8) from the dividend to 104 and continue with: 1048 / 485

On to step 5:
If we divide 1048 by 485, we get 2 and a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 970 from 1048, we get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 485

Advancing to step 6:
The number 485 fits into 789 1 times, leaving a remainder of 304.
Write down 1 as next digit of the result. 
Result so far: 421.0
The remainder is 304 after subtracting 485 from 789.
Take the next digit (2) from the dividend and append it to 304, then repeat: 3042 / 485

Advancing to step 7:
485 can be fit into 3042 6 times, resulting in a remainder of 132.
The next digit of our result is 6. 
Result so far: 4216.0
Deduct 2910 from 3042 and we're left with 132.
Bring next digit (0) of the dividend behind the 132 and repeat the process: 1320 / 485

Going ahead to step 8:
When dividing 1320 by 485, we get 2 with a remainder of 350.
Record the quotient 2 as the next digit in the result. 
Result so far: 42162.0
Subtract 970 from 1320 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 9:
485 can be fit into 3500 7 times, resulting in a remainder of 105.
Write down 7 as next digit of the result. 
Result so far: 42162.7
Subtract 3395 from 3500 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 10:
When dividing 1050 by 485, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 42162.72
If we take 970 away from 1050, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
If we divide 800 by 485, we get 1 and a remainder of 315.
The number 1 becomes the next digit in our result. 
Result so far: 42162.721
If we take 485 away from 800, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 12:
The number 485 fits into 3150 6 times, leaving a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 42162.7216
The remainder is 240 after subtracting 2910 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
2400 divided by 485 is 4 with a remainder of 460.
The next digit of our result is 4. 
Result so far: 42162.72164
Deduct 1940 from 2400 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 14:
4600 divided by 485 is 9 with a remainder of 235.
The number 9 becomes the next digit in our result. 
Result so far: 42162.721649
Deduct 4365 from 4600 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 15:
2350 divided by 485 is 4 with a remainder of 410.
Record the quotient 4 as the next digit in the result. 
Result so far: 42162.7216494
Subtracting 1940 from 2350 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 16:
485 goes into 4100 8 times with a remainder of 220.
The next digit of our result is 8. 
Result so far: 42162.72164948
Deduct 3880 from 4100 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The quotient of the division is 42162.72164948, and the remainder is 2.2e-07.
