We're dividing 48540099 by 90 
We're looking to find how many times 90 goes into 48540099.

Advancing to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 90

On to step 2:
90 goes into 48 0 times with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 90

Moving on to step 3:
The number 90 fits into 485 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 35 after subtracting 450 from 485.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 90

Going ahead to step 4:
If we divide 354 by 90, we get 3 and a remainder of 84.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we take 270 away from 354, we end up with 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 90

Going ahead to step 5:
840 divided by 90 is 9 with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 539.0
If we subtract 810 from 840, we get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 90

Moving on to step 6:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 5393.0
If we subtract 270 from 300, we get 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 90

Let's proceed to step 7:
90 can be fit into 309 3 times, resulting in a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 53933.0
If we take 270 away from 309, we end up with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 90

Let's proceed to step 8:
399 divided by 90 is 4 with a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 539334.0
Subtract 360 from 399 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
If we divide 390 by 90, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 539334.4
If we subtract 360 from 390, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
300 divided by 90 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 539334.43
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
If we divide 300 by 90, we get 3 and a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 539334.433
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 539334.433 with a balance of 0.003.
