21330164 divided by 485 
We're looking to find how many times 485 goes into 21330164.

On to step 1:
485 can be fit into 2 0 times, resulting in 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.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 485

Advancing to step 2:
When dividing 21 by 485, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 485

On to step 3:
The number 485 fits into 213 0 times, leaving a remainder of 213.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 213, we get 213.
Take the next digit (3) from the dividend and append it to 213, then repeat: 2133 / 485

Going ahead to step 4:
485 goes into 2133 4 times with a remainder of 193.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1940 from 2133 to get 193.
Include the next digit (0) from the dividend after 193, then repeat: 1930 / 485

On to step 5:
485 can be fit into 1930 3 times, resulting in a remainder of 475.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we take 1455 away from 1930, we end up with 475.
Bring next digit (1) of the dividend behind the 475 and repeat the process: 4751 / 485

Advancing to step 6:
When dividing 4751 by 485, we get 9 with a remainder of 386.
Use 9 as the next digit of our solution. 
Result so far: 439.0
Deduct 4365 from 4751 and we're left with 386.
Include the next digit (6) from the dividend after 386, then repeat: 3866 / 485

Let's proceed to step 7:
485 goes into 3866 7 times with a remainder of 471.
Record the quotient 7 as the next digit in the result. 
Result so far: 4397.0
Subtracting 3395 from 3866 leaves us with 471.
Bring next digit (4) of the dividend behind the 471 and repeat the process: 4714 / 485

Advancing to step 8:
485 goes into 4714 9 times with a remainder of 349.
The number 9 becomes the next digit in our result. 
Result so far: 43979.0
Subtract 4365 from 4714 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 9:
485 can be fit into 3490 7 times, resulting in a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 43979.7
Deduct 3395 from 3490 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 10:
The number 485 fits into 950 1 times, leaving a remainder of 465.
The number 1 becomes the next digit in our result. 
Result so far: 43979.71
Deduct 485 from 950 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 11:
When dividing 4650 by 485, we get 9 with a remainder of 285.
Write down 9 as next digit of the result. 
Result so far: 43979.719
Subtracting 4365 from 4650 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 12:
If we divide 2850 by 485, we get 5 and a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 43979.7195
Subtract 2425 from 2850 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 13:
4250 divided by 485 is 8 with a remainder of 370.
Record the quotient 8 as the next digit in the result. 
Result so far: 43979.71958
If we take 3880 away from 4250, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 14:
3700 divided by 485 is 7 with a remainder of 305.
The number 7 becomes the next digit in our result. 
Result so far: 43979.719587
Subtract 3395 from 3700 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 15:
If we divide 3050 by 485, we get 6 and a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 43979.7195876
The remainder is 140 after subtracting 2910 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 16:
1400 divided by 485 is 2 with a remainder of 430.
Put 2 as the next digit of the answer. 
Result so far: 43979.71958762
Subtracting 970 from 1400 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

The final result is 43979.71958762 with a remainder of 4.3e-07.
