991000 ÷ 16 
We want to figure out the number of times 991000 can be divided by 16.

Moving on to step 1:
If we divide 9 by 16, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 16

Advancing to step 2:
When dividing 99 by 16, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 96 from 99 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 16

On to step 3:
16 can be fit into 31 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we take 16 away from 31, we end up with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 16

Advancing to step 4:
The number 16 fits into 150 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 619.0
Subtracting 144 from 150 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 16

Step 5:
60 divided by 16 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 6193.0
Deduct 48 from 60 and we're left with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 16

Moving on to step 6:
The number 16 fits into 120 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 61937.0
Subtracting 112 from 120 leaves us 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 7:
16 can be fit into 80 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 61937.5
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.

Going ahead to step 8:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 61937.5
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.

Step 9:
When dividing 0 by 16, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 61937.5
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.

Our division results in 61937.5 with a remaining 0.0.
