We look at the division of 21143130 by 863 
We want to divide 21143130 by 863.

Going ahead to step 1:
The number 863 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 863

Step 2:
If we divide 21 by 863, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 863

Let's proceed to step 3:
863 can be fit into 211 0 times, resulting in a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Take the next digit (4) from the dividend and append it to 211, then repeat: 2114 / 863

On to step 4:
When dividing 2114 by 863, we get 2 with a remainder of 388.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1726 from 2114 to get 388.
Bring next digit (3) of the dividend behind the 388 and repeat the process: 3883 / 863

Step 5:
3883 divided by 863 is 4 with a remainder of 431.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtract 3452 from 3883 to get 431.
Append the next digit (1) from the dividend to 431 and continue with: 4311 / 863

Step 6:
If we divide 4311 by 863, we get 4 and a remainder of 859.
Write down 4 as next digit of the result. 
Result so far: 244.0
If we subtract 3452 from 4311, we get 859.
Take the next digit (3) from the dividend and append it to 859, then repeat: 8593 / 863

Step 7:
When dividing 8593 by 863, we get 9 with a remainder of 826.
The next digit of our result is 9. 
Result so far: 2449.0
If we take 7767 away from 8593, we end up with 826.
Grab the next digit (0) from the dividend, add it to 826, then carry on: 8260 / 863

Let's proceed to step 8:
863 can be fit into 8260 9 times, resulting in a remainder of 493.
Use 9 as the next digit of our solution. 
Result so far: 24499.0
If we take 7767 away from 8260, we end up with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Let's proceed to step 9:
When dividing 4930 by 863, we get 5 with a remainder of 615.
The next digit of our result is 5. 
Result so far: 24499.5
The remainder is 615 after subtracting 4315 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 10:
If we divide 6150 by 863, we get 7 and a remainder of 109.
Use 7 as the next digit of our solution. 
Result so far: 24499.57
Subtract 6041 from 6150 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 11:
1090 divided by 863 is 1 with a remainder of 227.
The next digit of our result is 1. 
Result so far: 24499.571
If we subtract 863 from 1090, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 12:
If we divide 2270 by 863, we get 2 and a remainder of 544.
Put 2 as the next digit of the answer. 
Result so far: 24499.5712
Subtract 1726 from 2270 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 13:
When dividing 5440 by 863, we get 6 with a remainder of 262.
Record the quotient 6 as the next digit in the result. 
Result so far: 24499.57126
Subtracting 5178 from 5440 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 14:
863 goes into 2620 3 times with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 24499.571263
Deduct 2589 from 2620 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 15:
863 goes into 310 0 times with a remainder of 310.
The next digit of our result is 0. 
Result so far: 24499.571263
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 16:
The number 863 fits into 3100 3 times, leaving a remainder of 511.
Use 3 as the next digit of our solution. 
Result so far: 24499.57126303
The remainder is 511 after subtracting 2589 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

The quotient of the division is 24499.57126303, and the remainder is 5.11e-07.
