12952812 divided by 90 
We want to figure out the number of times 12952812 can be divided by 90.

Let's proceed 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.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 90

Advancing to step 3:
If we divide 129 by 90, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 90 from 129, we get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 90

On to step 4:
The number 90 fits into 395 4 times, leaving a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 360 away from 395, we end up with 35.
Grab the next digit (2) from the dividend, add it to 35, then carry on: 352 / 90

Moving on to step 5:
The number 90 fits into 352 3 times, leaving a remainder of 82.
The next digit of our result is 3. 
Result so far: 143.0
Subtract 270 from 352 to get 82.
Take the next digit (8) from the dividend and append it to 82, then repeat: 828 / 90

Step 6:
90 can be fit into 828 9 times, resulting in a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 1439.0
Deduct 810 from 828 and we're left with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 90

Let's proceed to step 7:
If we divide 181 by 90, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 14392.0
Deduct 180 from 181 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 90

On to step 8:
90 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 143920.0
Deduct 0 from 12 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 90 fits into 120 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 143920.1
The remainder is 30 after subtracting 90 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
90 goes into 300 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 143920.13
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
When dividing 300 by 90, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 143920.133
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 143920.133 with a balance of 0.003.
