We divide 355849 by 90
We're looking to find how many times 90 goes into 355849.

Let's proceed to step 1:
90 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 90

Step 2:
90 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 90

Moving on to step 3:
90 can be fit into 355 3 times, resulting in a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 85 after subtracting 270 from 355.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 90

Advancing to step 4:
90 goes into 858 9 times with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 810 away from 858, we end up with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 90

Going ahead to step 5:
When dividing 484 by 90, we get 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 395.0
Deduct 450 from 484 and we're left with 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 90

Step 6:
If we divide 349 by 90, we get 3 and a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 3953.0
Deduct 270 from 349 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 7:
790 divided by 90 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 3953.8
Deduct 720 from 790 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 3953.87
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 3953.877
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 3953.877 with a remaining 0.007.
