611991 divided by 16 
Let's see how many times 16 fits into 611991.

Step 1:
16 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 16

Advancing to step 2:
The number 16 fits into 61 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 48 from 61 to get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 16

Going ahead to step 3:
16 can be fit into 131 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 38.0
The remainder is 3 after subtracting 128 from 131.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 16

Let's proceed to step 4:
The number 16 fits into 39 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 382.0
Subtracting 32 from 39 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 16

Advancing to step 5:
79 divided by 16 is 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 3824.0
Subtracting 64 from 79 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 16

Moving on to step 6:
151 divided by 16 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 38249.0
Deduct 144 from 151 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 16 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 38249.4
If we take 64 away from 70, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
The number 16 fits into 60 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 38249.43
If we subtract 48 from 60, we 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.

Let's proceed to step 9:
120 divided by 16 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 38249.437
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.

Advancing to step 10:
16 goes into 80 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 38249.4375
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.

Going ahead to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 38249.4375
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.

Step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 38249.4375
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.

In conclusion, the division gives 38249.4375 with a balance of 0.0.
