453454 ÷ 90 
We want to figure out the number of times 453454 can be divided by 90.

Going ahead to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 90

Let's proceed to step 2:
45 divided by 90 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 90

Let's proceed to step 3:
90 can be fit into 453 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 450 away from 453, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 90

Step 4:
90 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 90

Let's proceed to step 5:
The number 90 fits into 345 3 times, leaving a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 503.0
If we take 270 away from 345, we end up with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 90

Moving on to step 6:
754 divided by 90 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 5038.0
Subtract 720 from 754 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
The number 90 fits into 340 3 times, leaving a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 5038.3
If we subtract 270 from 340, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
90 goes into 700 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 5038.37
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 5038.377
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 5038.377 with a balance of 0.007.
