29142559 ÷ 90 
Our goal is to divide 29142559 by 90.

Let's proceed to step 1:
2 divided by 90 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 90

Advancing to step 2:
The number 90 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 90

On to step 3:
291 divided by 90 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 270 away from 291, we end up with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 90

Let's proceed to step 4:
90 goes into 214 2 times with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 180 from 214 and we're left with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 90

Moving on to step 5:
If we divide 342 by 90, we get 3 and a remainder of 72.
The next digit of our result is 3. 
Result so far: 323.0
If we take 270 away from 342, we end up with 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 90

Step 6:
The number 90 fits into 725 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 3238.0
If we subtract 720 from 725, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 90

Step 7:
When dividing 55 by 90, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 32380.0
Subtract 0 from 55 to get 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 90

Step 8:
The number 90 fits into 559 6 times, leaving a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 323806.0
Subtract 540 from 559 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
190 divided by 90 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 323806.2
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 90, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 323806.21
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
If we divide 100 by 90, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 323806.211
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 323806.211 with a remainder of 0.001.
