We divide 21319394 by 485
We want to figure out the number of times 21319394 can be divided by 485.

Step 1:
If we divide 2 by 485, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 485

Let's proceed to step 2:
The number 485 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 485

Going ahead to step 3:
485 goes into 213 0 times with a remainder of 213.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Grab the next digit (1) from the dividend, add it to 213, then carry on: 2131 / 485

Advancing to step 4:
The number 485 fits into 2131 4 times, leaving a remainder of 191.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 1940 from 2131, we get 191.
Fetch the next digit (9) from the dividend, attach it to 191 and continue: 1919 / 485

Step 5:
1919 divided by 485 is 3 with a remainder of 464.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we take 1455 away from 1919, we end up with 464.
Include the next digit (3) from the dividend after 464, then repeat: 4643 / 485

Going ahead to step 6:
485 can be fit into 4643 9 times, resulting in a remainder of 278.
The next digit of our result is 9. 
Result so far: 439.0
Deduct 4365 from 4643 and we're left with 278.
Take the next digit (9) from the dividend and append it to 278, then repeat: 2789 / 485

Going ahead to step 7:
If we divide 2789 by 485, we get 5 and a remainder of 364.
The next digit of our result is 5. 
Result so far: 4395.0
Deduct 2425 from 2789 and we're left with 364.
Take the next digit (4) from the dividend and append it to 364, then repeat: 3644 / 485

Let's proceed to step 8:
485 can be fit into 3644 7 times, resulting in a remainder of 249.
Write down 7 as next digit of the result. 
Result so far: 43957.0
If we subtract 3395 from 3644, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 9:
485 goes into 2490 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 43957.5
If we take 2425 away from 2490, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
650 divided by 485 is 1 with a remainder of 165.
Record the quotient 1 as the next digit in the result. 
Result so far: 43957.51
The remainder is 165 after subtracting 485 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 11:
485 can be fit into 1650 3 times, resulting in a remainder of 195.
Put 3 as the next digit of the answer. 
Result so far: 43957.513
Subtract 1455 from 1650 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 12:
485 goes into 1950 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 43957.5134
If we take 1940 away from 1950, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
485 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 43957.5134
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
The number 485 fits into 1000 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 43957.513402
The remainder is 30 after subtracting 970 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
The number 485 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 43957.513402
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 16:
485 goes into 3000 6 times with a remainder of 90.
Put 6 as the next digit of the answer. 
Result so far: 43957.51340206
Subtract 2910 from 3000 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 43957.51340206 with a remaining 9e-08.
