We look at the division of 520407 by 16 
Let's see how many times 16 fits into 520407.

Moving on to step 1:
16 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 16

Step 2:
When dividing 52 by 16, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 48 from 52 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 16

Step 3:
16 goes into 40 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Deduct 32 from 40 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 16

Going ahead to step 4:
The number 16 fits into 84 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 325.0
Deduct 80 from 84 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 16

Let's proceed to step 5:
40 divided by 16 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3252.0
Subtract 32 from 40 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 16

Advancing to step 6:
16 goes into 87 5 times with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 32525.0
If we subtract 80 from 87, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
16 goes into 70 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 32525.4
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 16 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 32525.43
The remainder is 12 after subtracting 48 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 32525.437
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.

Let's proceed to step 10:
80 divided by 16 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 32525.4375
The remainder is 0 after subtracting 80 from 80.
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: 32525.4375
The remainder is 0 after subtracting 0 from 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 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 32525.4375
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 quotient of the division is 32525.4375, and the remainder is 0.0.
