21858804 divided by 668 
We want to figure out the number of times 21858804 can be divided by 668.

Advancing to step 1:
668 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 668

Moving on to step 2:
When dividing 21 by 668, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 668

Advancing to step 3:
668 goes into 218 0 times with a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 218, we end up with 218.
Include the next digit (5) from the dividend after 218, then repeat: 2185 / 668

On to step 4:
When dividing 2185 by 668, we get 3 with a remainder of 181.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2004 away from 2185, we end up with 181.
Include the next digit (8) from the dividend after 181, then repeat: 1818 / 668

Step 5:
If we divide 1818 by 668, we get 2 and a remainder of 482.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 1336 from 1818, we get 482.
Bring next digit (8) of the dividend behind the 482 and repeat the process: 4828 / 668

Step 6:
668 goes into 4828 7 times with a remainder of 152.
Put 7 as the next digit of the answer. 
Result so far: 327.0
The remainder is 152 after subtracting 4676 from 4828.
Take the next digit (0) from the dividend and append it to 152, then repeat: 1520 / 668

Moving on to step 7:
1520 divided by 668 is 2 with a remainder of 184.
Put 2 as the next digit of the answer. 
Result so far: 3272.0
Subtracting 1336 from 1520 leaves us with 184.
Append the next digit (4) from the dividend to 184 and continue with: 1844 / 668

Going ahead to step 8:
When dividing 1844 by 668, we get 2 with a remainder of 508.
The number 2 becomes the next digit in our result. 
Result so far: 32722.0
If we take 1336 away from 1844, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 9:
The number 668 fits into 5080 7 times, leaving a remainder of 404.
Put 7 as the next digit of the answer. 
Result so far: 32722.7
Subtracting 4676 from 5080 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 10:
668 can be fit into 4040 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 32722.76
Subtracting 4008 from 4040 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
When dividing 320 by 668, we get 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 32722.76
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
668 goes into 3200 4 times with a remainder of 528.
The next digit of our result is 4. 
Result so far: 32722.7604
The remainder is 528 after subtracting 2672 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 13:
When dividing 5280 by 668, we get 7 with a remainder of 604.
The number 7 becomes the next digit in our result. 
Result so far: 32722.76047
Subtracting 4676 from 5280 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 14:
668 goes into 6040 9 times with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 32722.760479
Deduct 6012 from 6040 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 15:
668 can be fit into 280 0 times, resulting in a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 32722.760479
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
If we divide 2800 by 668, we get 4 and a remainder of 128.
The next digit of our result is 4. 
Result so far: 32722.76047904
Subtracting 2672 from 2800 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 32722.76047904 and a remainder of 1.28e-07.
