We divide 21854293 by 516
We want to figure out the number of times 21854293 can be divided by 516.

Step 1:
516 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 516

On to step 2:
516 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 516

Advancing to step 3:
If we divide 218 by 516, we get 0 and a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Take the next digit (5) from the dividend and append it to 218, then repeat: 2185 / 516

Advancing to step 4:
If we divide 2185 by 516, we get 4 and a remainder of 121.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 2064 from 2185 and we're left with 121.
Take the next digit (4) from the dividend and append it to 121, then repeat: 1214 / 516

Let's proceed to step 5:
When dividing 1214 by 516, we get 2 with a remainder of 182.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 1032 away from 1214, we end up with 182.
Fetch the next digit (2) from the dividend, attach it to 182 and continue: 1822 / 516

Let's proceed to step 6:
The number 516 fits into 1822 3 times, leaving a remainder of 274.
Record the quotient 3 as the next digit in the result. 
Result so far: 423.0
Deduct 1548 from 1822 and we're left with 274.
Include the next digit (9) from the dividend after 274, then repeat: 2749 / 516

Advancing to step 7:
If we divide 2749 by 516, we get 5 and a remainder of 169.
Put 5 as the next digit of the answer. 
Result so far: 4235.0
Subtracting 2580 from 2749 leaves us with 169.
Bring next digit (3) of the dividend behind the 169 and repeat the process: 1693 / 516

Advancing to step 8:
516 goes into 1693 3 times with a remainder of 145.
The next digit of our result is 3. 
Result so far: 42353.0
Subtract 1548 from 1693 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 9:
516 goes into 1450 2 times with a remainder of 418.
Put 2 as the next digit of the answer. 
Result so far: 42353.2
Subtract 1032 from 1450 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 10:
If we divide 4180 by 516, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 42353.28
If we subtract 4128 from 4180, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
If we divide 520 by 516, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 42353.281
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
40 divided by 516 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 42353.281
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
When dividing 400 by 516, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 42353.281
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 42353.281, and the remainder is 0.0004.
