Let's divide 42447375 by 9
Our goal is to divide 42447375 by 9.

Advancing to step 1:
When dividing 4 by 9, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 9

Moving on to step 2:
42 divided by 9 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 36 from 42 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 9

Step 3:
When dividing 64 by 9, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
The remainder is 1 after subtracting 63 from 64.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 9

Moving on to step 4:
9 can be fit into 14 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 471.0
Subtracting 9 from 14 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 9

Advancing to step 5:
9 can be fit into 57 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 4716.0
Subtract 54 from 57 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 9

Advancing to step 6:
If we divide 33 by 9, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 47163.0
If we take 27 away from 33, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 9

Moving on to step 7:
9 can be fit into 67 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 471637.0
If we take 63 away from 67, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 9

Going ahead to step 8:
If we divide 45 by 9, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4716375.0
If we take 45 away from 45, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4716375.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4716375.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4716375.0, with a leftover of 0.0.
