We're dividing 1566690 by 3 
Let's see how many times 3 fits into 1566690.

Going ahead to step 1:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

Advancing to step 2:
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: 5.0
If we subtract 15 from 15, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Let's proceed to step 3:
3 can be fit into 6 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 52.0
Subtracting 6 from 6 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Going ahead to step 4:
6 divided by 3 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 522.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Let's proceed to step 5:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 5222.0
If we take 6 away from 6, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

On to step 6:
The number 3 fits into 9 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 52223.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Advancing to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 522230.0
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.

On to step 8:
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: 522230.0
If we take 0 away from 0, we end up 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.

Step 9:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 522230.0
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 522230.0 with a balance of 0.0.
