21646013 ÷ 106 
Our goal is to divide 21646013 by 106.

Moving on to step 1:
2 divided by 106 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 106

Moving on to step 2:
If we divide 21 by 106, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 106

Going ahead to step 3:
216 divided by 106 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 4 after subtracting 212 from 216.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 106

Step 4:
106 can be fit into 44 0 times, resulting in a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 44 leaves us with 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 106

On to step 5:
When dividing 446 by 106, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 204.0
Deduct 424 from 446 and we're left with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 106

Advancing to step 6:
106 can be fit into 220 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2042.0
Subtract 212 from 220 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 106

Advancing to step 7:
81 divided by 106 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 20420.0
If we take 0 away from 81, we end up with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 106

Advancing to step 8:
When dividing 813 by 106, we get 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 204207.0
If we subtract 742 from 813, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
106 goes into 710 6 times with a remainder of 74.
The next digit of our result is 6. 
Result so far: 204207.6
Deduct 636 from 710 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
If we divide 740 by 106, we get 6 and a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 204207.66
Subtract 636 from 740 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 204207.66, with a leftover of 0.104.
