We look at the division of 21427415 by 519 
Let's see how many times 519 fits into 21427415.

Moving on to step 1:
The number 519 fits into 2 0 times, leaving 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.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 519

On to step 2:
The number 519 fits into 21 0 times, leaving 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.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 519

Let's proceed to step 3:
If we divide 214 by 519, we get 0 and a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Fetch the next digit (2) from the dividend, attach it to 214 and continue: 2142 / 519

Let's proceed to step 4:
When dividing 2142 by 519, we get 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 2076 away from 2142, we end up with 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 519

On to step 5:
When dividing 667 by 519, we get 1 with a remainder of 148.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 519 from 667 and we're left with 148.
Include the next digit (4) from the dividend after 148, then repeat: 1484 / 519

Going ahead to step 6:
When dividing 1484 by 519, we get 2 with a remainder of 446.
The next digit of our result is 2. 
Result so far: 412.0
If we take 1038 away from 1484, we end up with 446.
Grab the next digit (1) from the dividend, add it to 446, then carry on: 4461 / 519

Let's proceed to step 7:
4461 divided by 519 is 8 with a remainder of 309.
Use 8 as the next digit of our solution. 
Result so far: 4128.0
If we take 4152 away from 4461, we end up with 309.
Fetch the next digit (5) from the dividend, attach it to 309 and continue: 3095 / 519

Moving on to step 8:
The number 519 fits into 3095 5 times, leaving a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 41285.0
If we subtract 2595 from 3095, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 9:
519 goes into 5000 9 times with a remainder of 329.
Write down 9 as next digit of the result. 
Result so far: 41285.9
The remainder is 329 after subtracting 4671 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 10:
The number 519 fits into 3290 6 times, leaving a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 41285.96
If we subtract 3114 from 3290, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 11:
If we divide 1760 by 519, we get 3 and a remainder of 203.
Write down 3 as next digit of the result. 
Result so far: 41285.963
Subtracting 1557 from 1760 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 12:
519 can be fit into 2030 3 times, resulting in a remainder of 473.
The number 3 becomes the next digit in our result. 
Result so far: 41285.9633
Subtracting 1557 from 2030 leaves us with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

After the division, we end up with 41285.9633 and a remainder of 0.00473.
