We look at the division of 44342951 by 90 
We want to divide 44342951 by 90.

On to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 90

Step 2:
44 divided by 90 is 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 90

Advancing to step 3:
If we divide 443 by 90, we get 4 and a remainder of 83.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 360 from 443 to get 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 90

Let's proceed to step 4:
When dividing 834 by 90, we get 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 810 away from 834, we end up with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 90

Advancing to step 5:
90 goes into 242 2 times with a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 492.0
Subtract 180 from 242 to get 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 90

Moving on to step 6:
The number 90 fits into 629 6 times, leaving a remainder of 89.
Record the quotient 6 as the next digit in the result. 
Result so far: 4926.0
Subtract 540 from 629 to get 89.
Grab the next digit (5) from the dividend, add it to 89, then carry on: 895 / 90

Step 7:
If we divide 895 by 90, we get 9 and a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 49269.0
Deduct 810 from 895 and we're left with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 90

Advancing to step 8:
The number 90 fits into 851 9 times, leaving a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 492699.0
Subtract 810 from 851 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
90 goes into 410 4 times with a remainder of 50.
The next digit of our result is 4. 
Result so far: 492699.4
If we take 360 away from 410, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 90, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 492699.45
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
If we divide 500 by 90, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 492699.455
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 492699.455 and a remainder of 0.005.
