We divide 21008866 by 530
Our goal is to divide 21008866 by 530.

On to step 1:
If we divide 2 by 530, we get 0 and 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 530

Let's proceed to step 2:
530 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
The remainder is 21 after subtracting 0 from 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 530

Step 3:
210 divided by 530 is 0 with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Bring next digit (0) of the dividend behind the 210 and repeat the process: 2100 / 530

Moving on to step 4:
530 can be fit into 2100 3 times, resulting in a remainder of 510.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1590 away from 2100, we end up with 510.
Fetch the next digit (8) from the dividend, attach it to 510 and continue: 5108 / 530

Let's proceed to step 5:
If we divide 5108 by 530, we get 9 and a remainder of 338.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 4770 from 5108 to get 338.
Bring next digit (8) of the dividend behind the 338 and repeat the process: 3388 / 530

Moving on to step 6:
530 can be fit into 3388 6 times, resulting in a remainder of 208.
The number 6 becomes the next digit in our result. 
Result so far: 396.0
If we take 3180 away from 3388, we end up with 208.
Fetch the next digit (6) from the dividend, attach it to 208 and continue: 2086 / 530

Advancing to step 7:
When dividing 2086 by 530, we get 3 with a remainder of 496.
The next digit of our result is 3. 
Result so far: 3963.0
The remainder is 496 after subtracting 1590 from 2086.
Take the next digit (6) from the dividend and append it to 496, then repeat: 4966 / 530

Step 8:
The number 530 fits into 4966 9 times, leaving a remainder of 196.
Write down 9 as next digit of the result. 
Result so far: 39639.0
Subtracting 4770 from 4966 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 9:
When dividing 1960 by 530, we get 3 with a remainder of 370.
Put 3 as the next digit of the answer. 
Result so far: 39639.3
The remainder is 370 after subtracting 1590 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
When dividing 3700 by 530, we get 6 with a remainder of 520.
Record the quotient 6 as the next digit in the result. 
Result so far: 39639.36
Deduct 3180 from 3700 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 11:
530 can be fit into 5200 9 times, resulting in a remainder of 430.
The next digit of our result is 9. 
Result so far: 39639.369
Deduct 4770 from 5200 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 12:
530 goes into 4300 8 times with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 39639.3698
Deduct 4240 from 4300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
When dividing 600 by 530, we get 1 with a remainder of 70.
The next digit of our result is 1. 
Result so far: 39639.36981
The remainder is 70 after subtracting 530 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
530 goes into 700 1 times with a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 39639.369811
Subtract 530 from 700 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 39639.369811, with a leftover of 1.7e-05.
