We divide 901522 by 45
Our goal is to divide 901522 by 45.

Moving on to step 1:
9 divided by 45 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 45

On to step 2:
45 goes into 90 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 90 from 90, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 45

Going ahead to step 3:
If we divide 1 by 45, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 45

Going ahead to step 4:
45 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 200.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 45

Advancing to step 5:
If we divide 152 by 45, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 2003.0
The remainder is 17 after subtracting 135 from 152.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 45

Advancing to step 6:
172 divided by 45 is 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 20033.0
Deduct 135 from 172 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
If we divide 370 by 45, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 20033.8
If we take 360 away from 370, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 45, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 20033.82
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
If we divide 100 by 45, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 20033.822
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 20033.822 and a remainder of 0.001.
