We look at the division of 371449 by 90 
We want to figure out the number of times 371449 can be divided by 90.

Moving on to step 1:
90 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 90

Step 2:
When dividing 37 by 90, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 90

On to step 3:
The number 90 fits into 371 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 360 from 371 and we're left with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 90

Let's proceed to step 4:
When dividing 114 by 90, we get 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtract 90 from 114 to get 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 90

On to step 5:
When dividing 244 by 90, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 412.0
If we subtract 180 from 244, we get 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 90

Let's proceed to step 6:
If we divide 649 by 90, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 4127.0
Subtracting 630 from 649 leaves us with 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 7:
When dividing 190 by 90, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 4127.2
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.

Let's proceed to step 8:
When dividing 100 by 90, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 4127.21
Deduct 90 from 100 and we're left 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.

On to step 9:
90 goes into 100 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 4127.211
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.

After the division, we end up with 4127.211 and a remainder of 0.001.
