Let's divide 90393950 by 16
Our goal is to divide 90393950 by 16.

On to step 1:
16 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 16

Moving on to step 2:
90 divided by 16 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5.0
If we take 80 away from 90, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 16

Advancing to step 3:
16 goes into 103 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 96 from 103 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 16

Going ahead to step 4:
The number 16 fits into 79 4 times, leaving a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 564.0
If we subtract 64 from 79, we get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 16

Step 5:
The number 16 fits into 153 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 5649.0
If we subtract 144 from 153, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 16

Going ahead to step 6:
16 goes into 99 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 56496.0
Subtract 96 from 99 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 16

Let's proceed to step 7:
If we divide 35 by 16, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 564962.0
The remainder is 3 after subtracting 32 from 35.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 16

Going ahead to step 8:
The number 16 fits into 30 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 5649621.0
If we subtract 16 from 30, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
The number 16 fits into 140 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5649621.8
The remainder is 12 after subtracting 128 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
120 divided by 16 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 5649621.87
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 16, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5649621.875
Subtract 80 from 80 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.

Advancing to step 12:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5649621.875
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.

Moving on to step 13:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5649621.875
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.

In conclusion, the division gives 5649621.875 with a balance of 0.0.
