We're dividing 91007590 by 450 
Our goal is to divide 91007590 by 450.

Let's proceed to step 1:
If we divide 9 by 450, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 450

Going ahead to step 2:
The number 450 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Append the next digit (0) from the dividend to 91 and continue with: 910 / 450

Let's proceed to step 3:
When dividing 910 by 450, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 900 away from 910, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 450

Step 4:
450 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 100, we end up with 100.
Include the next digit (7) from the dividend after 100, then repeat: 1007 / 450

Going ahead to step 5:
When dividing 1007 by 450, we get 2 with a remainder of 107.
Write down 2 as next digit of the result. 
Result so far: 202.0
Subtracting 900 from 1007 leaves us with 107.
Grab the next digit (5) from the dividend, add it to 107, then carry on: 1075 / 450

Moving on to step 6:
If we divide 1075 by 450, we get 2 and a remainder of 175.
Put 2 as the next digit of the answer. 
Result so far: 2022.0
If we take 900 away from 1075, we end up with 175.
Append the next digit (9) from the dividend to 175 and continue with: 1759 / 450

On to step 7:
1759 divided by 450 is 3 with a remainder of 409.
Put 3 as the next digit of the answer. 
Result so far: 20223.0
The remainder is 409 after subtracting 1350 from 1759.
Append the next digit (0) from the dividend to 409 and continue with: 4090 / 450

Step 8:
The number 450 fits into 4090 9 times, leaving a remainder of 40.
The next digit of our result is 9. 
Result so far: 202239.0
If we subtract 4050 from 4090, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 450 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 202239.0
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 10:
The number 450 fits into 4000 8 times, leaving a remainder of 400.
Record the quotient 8 as the next digit in the result. 
Result so far: 202239.08
Subtract 3600 from 4000 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
When dividing 4000 by 450, we get 8 with a remainder of 400.
Write down 8 as next digit of the result. 
Result so far: 202239.088
Deduct 3600 from 4000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 202239.088 with a balance of 0.04.
