We look at the division of 521598 by 16 
We're looking to find how many times 16 goes into 521598.

Moving on to step 1:
16 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 16

Moving on to step 2:
If we divide 52 by 16, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 48 from 52 and we're left with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 16

Step 3:
When dividing 41 by 16, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
The remainder is 9 after subtracting 32 from 41.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 16

On to step 4:
16 can be fit into 95 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 325.0
If we take 80 away from 95, we end up with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 16

Going ahead to step 5:
When dividing 159 by 16, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 3259.0
Subtracting 144 from 159 leaves us with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 16

Let's proceed to step 6:
16 can be fit into 158 9 times, resulting in a remainder of 14.
The next digit of our result is 9. 
Result so far: 32599.0
Subtracting 144 from 158 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
16 goes into 140 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 32599.8
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.

Moving on to step 8:
When dividing 120 by 16, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 32599.87
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
16 goes into 80 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 32599.875
Deduct 80 from 80 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.

Let's proceed to step 10:
When dividing 0 by 16, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 32599.875
If we take 0 away from 0, 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.

Advancing to step 11:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 32599.875
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.

The final outcome is 32599.875, with a leftover of 0.0.
