21003739 divided by 514 
Our goal is to divide 21003739 by 514.

Step 1:
If we divide 2 by 514, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 514

On to step 2:
514 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 514

Going ahead to step 3:
If we divide 210 by 514, we get 0 and a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Grab the next digit (0) from the dividend, add it to 210, then carry on: 2100 / 514

Advancing to step 4:
When dividing 2100 by 514, we get 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 2056 from 2100 leaves us with 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 514

On to step 5:
When dividing 443 by 514, we get 0 with a remainder of 443.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 443 to get 443.
Fetch the next digit (7) from the dividend, attach it to 443 and continue: 4437 / 514

On to step 6:
When dividing 4437 by 514, we get 8 with a remainder of 325.
Write down 8 as next digit of the result. 
Result so far: 408.0
If we take 4112 away from 4437, we end up with 325.
Grab the next digit (3) from the dividend, add it to 325, then carry on: 3253 / 514

Step 7:
514 goes into 3253 6 times with a remainder of 169.
Put 6 as the next digit of the answer. 
Result so far: 4086.0
Deduct 3084 from 3253 and we're left with 169.
Take the next digit (9) from the dividend and append it to 169, then repeat: 1699 / 514

Advancing to step 8:
When dividing 1699 by 514, we get 3 with a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 40863.0
If we take 1542 away from 1699, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
The number 514 fits into 1570 3 times, leaving a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 40863.3
If we subtract 1542 from 1570, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
514 can be fit into 280 0 times, resulting in a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 40863.3
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
514 goes into 2800 5 times with a remainder of 230.
The next digit of our result is 5. 
Result so far: 40863.305
If we take 2570 away from 2800, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
The number 514 fits into 2300 4 times, leaving a remainder of 244.
Record the quotient 4 as the next digit in the result. 
Result so far: 40863.3054
Deduct 2056 from 2300 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 13:
2440 divided by 514 is 4 with a remainder of 384.
The number 4 becomes the next digit in our result. 
Result so far: 40863.30544
Subtracting 2056 from 2440 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

After the division, we end up with 40863.30544 and a remainder of 0.000384.
