We're dividing 48219921 by 9 
We want to figure out the number of times 48219921 can be divided by 9.

Let's proceed to step 1:
9 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 9

Moving on to step 2:
9 can be fit into 48 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 45 away from 48, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 9

Going ahead to step 3:
When dividing 32 by 9, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 53.0
If we take 27 away from 32, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 9

Moving on to step 4:
9 goes into 51 5 times with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 535.0
Subtract 45 from 51 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 9

Moving on to step 5:
9 can be fit into 69 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 5357.0
If we take 63 away from 69, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 9

Let's proceed to step 6:
The number 9 fits into 69 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 53577.0
Deduct 63 from 69 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 9

Going ahead to step 7:
9 goes into 62 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 535776.0
The remainder is 8 after subtracting 54 from 62.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 9

Going ahead to step 8:
9 can be fit into 81 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 5357769.0
If we subtract 81 from 81, 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.

Advancing to step 9:
0 divided by 9 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5357769.0
Subtract 0 from 0 to 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:
If we divide 0 by 9, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5357769.0
Deduct 0 from 0 and we're left 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 quotient of the division is 5357769.0, and the remainder is 0.0.
