12946533 ÷ 90 
We want to divide 12946533 by 90.

Moving on to step 1:
If we divide 1 by 90, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 90

Let's proceed to step 2:
90 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 90

Going ahead to step 3:
129 divided by 90 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 90 from 129 and we're left with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 90

Let's proceed to step 4:
The number 90 fits into 394 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 360 from 394 to get 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 90

Step 5:
90 goes into 346 3 times with a remainder of 76.
The next digit of our result is 3. 
Result so far: 143.0
Subtracting 270 from 346 leaves us with 76.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 90

On to step 6:
When dividing 765 by 90, we get 8 with a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 1438.0
Subtract 720 from 765 to get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 90

Going ahead to step 7:
453 divided by 90 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 14385.0
Subtracting 450 from 453 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 90

Moving on to step 8:
90 can be fit into 33 0 times, resulting in a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 143850.0
Subtracting 0 from 33 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
330 divided by 90 is 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 143850.3
If we take 270 away from 330, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
When dividing 600 by 90, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 143850.36
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
600 divided by 90 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 143850.366
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 143850.366 with a remaining 0.006.
