Let's divide 21640829 by 668
Our goal is to divide 21640829 by 668.

Step 1:
2 divided by 668 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 668

On to step 2:
21 divided by 668 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 668

Let's proceed to step 3:
When dividing 216 by 668, we get 0 with a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Append the next digit (4) from the dividend to 216 and continue with: 2164 / 668

Let's proceed to step 4:
The number 668 fits into 2164 3 times, leaving a remainder of 160.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 2004 from 2164 to get 160.
Append the next digit (0) from the dividend to 160 and continue with: 1600 / 668

On to step 5:
When dividing 1600 by 668, we get 2 with a remainder of 264.
The next digit of our result is 2. 
Result so far: 32.0
If we take 1336 away from 1600, we end up with 264.
Include the next digit (8) from the dividend after 264, then repeat: 2648 / 668

Going ahead to step 6:
When dividing 2648 by 668, we get 3 with a remainder of 644.
Record the quotient 3 as the next digit in the result. 
Result so far: 323.0
Subtracting 2004 from 2648 leaves us with 644.
Include the next digit (2) from the dividend after 644, then repeat: 6442 / 668

Step 7:
When dividing 6442 by 668, we get 9 with a remainder of 430.
Record the quotient 9 as the next digit in the result. 
Result so far: 3239.0
Subtracting 6012 from 6442 leaves us with 430.
Append the next digit (9) from the dividend to 430 and continue with: 4309 / 668

Advancing to step 8:
668 can be fit into 4309 6 times, resulting in a remainder of 301.
The next digit of our result is 6. 
Result so far: 32396.0
Deduct 4008 from 4309 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 9:
If we divide 3010 by 668, we get 4 and a remainder of 338.
Write down 4 as next digit of the result. 
Result so far: 32396.4
If we take 2672 away from 3010, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
3380 divided by 668 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 32396.45
The remainder is 40 after subtracting 3340 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
If we divide 400 by 668, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 32396.45
Deduct 0 from 400 and we're left 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.

Advancing to step 12:
When dividing 4000 by 668, we get 5 with a remainder of 660.
Record the quotient 5 as the next digit in the result. 
Result so far: 32396.4505
The remainder is 660 after subtracting 3340 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 13:
The number 668 fits into 6600 9 times, leaving a remainder of 588.
Record the quotient 9 as the next digit in the result. 
Result so far: 32396.45059
Subtract 6012 from 6600 to get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Going ahead to step 14:
When dividing 5880 by 668, we get 8 with a remainder of 536.
Record the quotient 8 as the next digit in the result. 
Result so far: 32396.450598
Deduct 5344 from 5880 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 15:
When dividing 5360 by 668, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 32396.4505988
Deduct 5344 from 5360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 32396.4505988 and a remainder of 1.6e-07.
