Let's divide 354052 by 90
We're looking to find how many times 90 goes into 354052.

Moving on to step 1:
If we divide 3 by 90, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 90

Let's proceed to step 2:
When dividing 35 by 90, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 90

Let's proceed to step 3:
90 can be fit into 354 3 times, resulting in a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 270 from 354 and we're left with 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 90

Moving on to step 4:
90 goes into 840 9 times with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 810 from 840 and we're left with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 90

Let's proceed to step 5:
90 goes into 305 3 times with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 393.0
Subtracting 270 from 305 leaves us with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 90

On to step 6:
90 goes into 352 3 times with a remainder of 82.
The next digit of our result is 3. 
Result so far: 3933.0
The remainder is 82 after subtracting 270 from 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 7:
If we divide 820 by 90, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 3933.9
Subtracting 810 from 820 leaves us 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.

Advancing to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 3933.91
If we subtract 90 from 100, we 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 9:
100 divided by 90 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 3933.911
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.

After the division, we end up with 3933.911 and a remainder of 0.001.
