Let's divide 438490 by 45
Our goal is to divide 438490 by 45.

Let's proceed to step 1:
The number 45 fits into 4 0 times, leaving 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 (3) from the dividend and append it to 4, then repeat: 43 / 45

Let's proceed to step 2:
When dividing 43 by 45, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 45

Advancing to step 3:
If we divide 438 by 45, we get 9 and a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 405 from 438 and we're left with 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 45

Going ahead to step 4:
The number 45 fits into 334 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtract 315 from 334 to get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 45

Step 5:
45 goes into 199 4 times with a remainder of 19.
The next digit of our result is 4. 
Result so far: 974.0
Deduct 180 from 199 and we're left with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 45

Step 6:
When dividing 190 by 45, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 9744.0
If we take 180 away from 190, 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.

On to step 7:
When dividing 100 by 45, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 9744.2
Deduct 90 from 100 and we're left 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.

Let's proceed to step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 9744.22
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.

The final outcome is 9744.22, with a leftover of 0.01.
