We divide 21321516 by 479
We want to figure out the number of times 21321516 can be divided by 479.

Step 1:
479 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 479

Let's proceed to step 2:
21 divided by 479 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 479

Moving on to step 3:
The number 479 fits into 213 0 times, leaving a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Fetch the next digit (2) from the dividend, attach it to 213 and continue: 2132 / 479

Let's proceed to step 4:
If we divide 2132 by 479, we get 4 and a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 1916 away from 2132, we end up with 216.
Fetch the next digit (1) from the dividend, attach it to 216 and continue: 2161 / 479

Let's proceed to step 5:
479 can be fit into 2161 4 times, resulting in a remainder of 245.
Put 4 as the next digit of the answer. 
Result so far: 44.0
The remainder is 245 after subtracting 1916 from 2161.
Take the next digit (5) from the dividend and append it to 245, then repeat: 2455 / 479

Step 6:
The number 479 fits into 2455 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 445.0
Subtract 2395 from 2455 to get 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 479

Moving on to step 7:
479 goes into 601 1 times with a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 4451.0
If we subtract 479 from 601, we get 122.
Grab the next digit (6) from the dividend, add it to 122, then carry on: 1226 / 479

Step 8:
When dividing 1226 by 479, we get 2 with a remainder of 268.
Use 2 as the next digit of our solution. 
Result so far: 44512.0
If we take 958 away from 1226, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 9:
If we divide 2680 by 479, we get 5 and a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 44512.5
If we take 2395 away from 2680, we end up 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 10:
If we divide 2850 by 479, we get 5 and a remainder of 455.
The next digit of our result is 5. 
Result so far: 44512.55
If we subtract 2395 from 2850, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

The quotient of the division is 44512.55, and the remainder is 0.455.
