76803142 ÷ 16 
We want to divide 76803142 by 16.

Step 1:
If we divide 7 by 16, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 16

Step 2:
If we divide 76 by 16, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 64 from 76 to get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 16

Moving on to step 3:
16 goes into 128 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 128 from 128 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 16

Step 4:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
Subtract 0 from 0 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 16

Step 5:
If we divide 3 by 16, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 4800.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 16

Advancing to step 6:
If we divide 31 by 16, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 48001.0
If we subtract 16 from 31, we get 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 16

Advancing to step 7:
16 can be fit into 154 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 480019.0
If we subtract 144 from 154, we get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 16

Step 8:
102 divided by 16 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 4800196.0
The remainder is 6 after subtracting 96 from 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 16, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 4800196.3
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.

Step 10:
120 divided by 16 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 4800196.37
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.

Let's proceed to step 11:
16 goes into 80 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4800196.375
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.

Let's proceed to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4800196.375
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.

Going ahead to step 13:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4800196.375
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.

After the division, we end up with 4800196.375 and a remainder of 0.0.
