We divide 45245751 by 90
Let's see how many times 90 fits into 45245751.

Let's proceed to step 1:
90 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 90

Step 2:
The number 90 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 90

Going ahead to step 3:
452 divided by 90 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 2 after subtracting 450 from 452.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 90

On to step 4:
The number 90 fits into 24 0 times, leaving a remainder of 24.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 24 and we're left with 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 90

Let's proceed to step 5:
90 goes into 245 2 times with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 502.0
Deduct 180 from 245 and we're left with 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 90

Step 6:
The number 90 fits into 657 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 5027.0
If we subtract 630 from 657, we get 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 90

Let's proceed to step 7:
When dividing 275 by 90, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 50273.0
If we take 270 away from 275, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 90

On to step 8:
If we divide 51 by 90, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 502730.0
Subtract 0 from 51 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
When dividing 510 by 90, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 502730.5
Subtract 450 from 510 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The next digit of our result is 6. 
Result so far: 502730.56
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 502730.566
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 502730.566 with a balance of 0.006.
