Let's divide 451330 by 90
We want to divide 451330 by 90.

Let's proceed 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
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 90

Advancing to step 2:
When dividing 45 by 90, we get 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 90

Going ahead to step 3:
If we divide 451 by 90, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 450 from 451, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 90

Advancing to step 4:
90 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 90

Advancing to step 5:
The number 90 fits into 133 1 times, leaving a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 501.0
Deduct 90 from 133 and we're left with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 90

Advancing to step 6:
The number 90 fits into 430 4 times, leaving a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 5014.0
If we take 360 away from 430, we end up 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 7:
If we divide 700 by 90, we get 7 and a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 5014.7
If we take 630 away from 700, we end up 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 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
The next digit of our result is 7. 
Result so far: 5014.77
If we subtract 630 from 700, 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.

Our division results in 5014.77 with a remaining 0.07.
