We're dividing 999420 by 16 
We want to figure out the number of times 999420 can be divided by 16.

Advancing to step 1:
16 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 16

Moving on to step 2:
If we divide 99 by 16, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 96 from 99 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 16

On to step 3:
16 can be fit into 39 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Subtract 32 from 39 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 16

Going ahead to step 4:
16 can be fit into 74 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 624.0
Subtracting 64 from 74 leaves us with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 16

Going ahead to step 5:
The number 16 fits into 102 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6246.0
If we take 96 away from 102, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 16

Going ahead to step 6:
The number 16 fits into 60 3 times, leaving a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 62463.0
If we take 48 away from 60, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
When dividing 120 by 16, we get 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 62463.7
If we take 112 away from 120, we end up 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.

Going ahead to step 8:
80 divided by 16 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 62463.75
Subtracting 80 from 80 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.

Step 9:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 62463.75
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.

Going ahead to step 10:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62463.75
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 62463.75, with a leftover of 0.0.
