We divide 201553 by 45
Let's see how many times 45 fits into 201553.

Advancing to step 1:
The number 45 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 45

Advancing to step 2:
If we divide 20 by 45, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 45

Moving on to step 3:
When dividing 201 by 45, we get 4 with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 180 away from 201, we end up with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 45

Advancing to step 4:
When dividing 215 by 45, we get 4 with a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtracting 180 from 215 leaves us with 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 45

On to step 5:
355 divided by 45 is 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 447.0
If we take 315 away from 355, we end up with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 45

Advancing to step 6:
The number 45 fits into 403 8 times, leaving a remainder of 43.
The next digit of our result is 8. 
Result so far: 4478.0
Subtract 360 from 403 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
If we divide 430 by 45, we get 9 and a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 4478.9
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4478.95
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4478.955
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 4478.955 and a remainder of 0.0025.
