106521 ÷ 3 
Let's see how many times 3 fits into 106521.

Advancing to step 1:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

Let's proceed to step 2:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 9 away from 10, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 3

Step 3:
16 divided by 3 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 15 from 16 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Advancing to step 4:
15 divided by 3 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Deduct 15 from 15 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Let's proceed to step 5:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 3550.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Moving on to step 6:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 35507.0
If we subtract 21 from 21, 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.

Let's proceed to step 7:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 35507.0
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:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35507.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 35507.0, and the remainder is 0.0.
