642837 ÷ 16 
Our goal is to divide 642837 by 16.

Let's proceed to step 1:
If we divide 6 by 16, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 16

Let's proceed to step 2:
16 can be fit into 64 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 64 away from 64, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 16

Advancing to step 3:
When dividing 2 by 16, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 16

Let's proceed to step 4:
The number 16 fits into 28 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 401.0
The remainder is 12 after subtracting 16 from 28.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 16

Advancing to step 5:
When dividing 123 by 16, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 4017.0
Subtract 112 from 123 to get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 16

Moving on to step 6:
When dividing 117 by 16, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 40177.0
The remainder is 5 after subtracting 112 from 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
16 can be fit into 50 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 40177.3
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 16, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 40177.31
If we take 16 away from 20, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 16, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 40177.312
Subtracting 32 from 40 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.

Going ahead to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 40177.3125
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.

Moving on to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 40177.3125
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 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40177.3125
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.

The final outcome is 40177.3125, with a leftover of 0.0.
