991550 divided by 16 
We're looking to find how many times 16 goes into 991550.

Step 1:
16 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 16

Advancing to step 2:
16 goes into 99 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 96 from 99 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 16

On to step 3:
When dividing 31 by 16, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 61.0
The remainder is 15 after subtracting 16 from 31.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 16

Step 4:
If we divide 155 by 16, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 619.0
The remainder is 11 after subtracting 144 from 155.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 16

Advancing to step 5:
When dividing 115 by 16, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 6197.0
The remainder is 3 after subtracting 112 from 115.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 16

Step 6:
30 divided by 16 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 61971.0
If we take 16 away from 30, we end up 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.

Going ahead to step 7:
140 divided by 16 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 61971.8
Subtract 128 from 140 to get 12.
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 8:
120 divided by 16 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 61971.87
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.

Moving on to step 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 61971.875
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.

Step 10:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 61971.875
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.

On to step 11:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 61971.875
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.

The quotient of the division is 61971.875, and the remainder is 0.0.
