We divide 361899 by 90
We're looking to find how many times 90 goes into 361899.

Advancing to step 1:
90 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 90

Moving on to step 2:
90 goes into 36 0 times with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 90

Step 3:
90 goes into 361 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 360 from 361 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 90

Going ahead to step 4:
If we divide 18 by 90, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 18 to get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 90

Moving on to step 5:
90 can be fit into 189 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 402.0
If we take 180 away from 189, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 90

Let's proceed to step 6:
The number 90 fits into 99 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 4021.0
The remainder is 9 after subtracting 90 from 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 90, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 4021.1
If we subtract 90 from 90, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
90 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4021.1
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4021.1
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4021.1 and a remainder of 0.0.
