452058 ÷ 90 
We're looking to find how many times 90 goes into 452058.

On to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 90

Going ahead to step 2:
90 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 90

Moving on to step 3:
90 goes into 452 5 times with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 450 from 452, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 90

Step 4:
The number 90 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 20, we get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 90

Step 5:
205 divided by 90 is 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 502.0
Deduct 180 from 205 and we're left with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 90

Moving on to step 6:
90 can be fit into 258 2 times, resulting in a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 5022.0
If we take 180 away from 258, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 7:
The number 90 fits into 780 8 times, leaving a remainder of 60.
The next digit of our result is 8. 
Result so far: 5022.8
Subtracting 720 from 780 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 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 5022.86
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.

Going ahead to step 9:
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: 5022.866
If we subtract 540 from 600, we 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.

The final outcome is 5022.866, with a leftover of 0.006.
