Let's divide 21495606 by 3
Let's see how many times 3 fits into 21495606.

Moving on to step 1:
3 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Advancing to step 2:
When dividing 21 by 3, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 21 from 21 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Let's proceed to step 3:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we take 3 away from 4, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

Step 4:
3 can be fit into 19 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 716.0
Subtract 18 from 19 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Step 5:
If we divide 15 by 3, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7165.0
Deduct 15 from 15 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Moving on to step 6:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 71652.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

On to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 716520.0
If we take 0 away from 0, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Let's proceed to step 8:
If we divide 6 by 3, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 7165202.0
The remainder is 0 after subtracting 6 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 3, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7165202.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 7165202.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 7165202.0 and a remainder of 0.0.
