810551 ÷ 16 
We want to divide 810551 by 16.

Going ahead to step 1:
When dividing 8 by 16, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 16

Going ahead to step 2:
If we divide 81 by 16, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 80 from 81, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 16

Let's proceed to step 3:
16 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 16

Going ahead to step 4:
105 divided by 16 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 506.0
Subtracting 96 from 105 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 16

Going ahead to step 5:
16 can be fit into 95 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5065.0
If we subtract 80 from 95, we get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 16

Advancing to step 6:
The number 16 fits into 151 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 50659.0
If we subtract 144 from 151, 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.

Going ahead to step 7:
70 divided by 16 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 50659.4
Deduct 64 from 70 and we're left 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:
16 can be fit into 60 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 50659.43
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:
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: 50659.437
If we subtract 112 from 120, we 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.

On 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: 50659.4375
If we subtract 80 from 80, 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.

Moving on to step 11:
16 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 50659.4375
Subtract 0 from 0 to 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.

Going ahead to step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 50659.4375
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.

After the division, we end up with 50659.4375 and a remainder of 0.0.
