Let's divide 65872891 by 16
We want to figure out the number of times 65872891 can be divided by 16.

Going ahead to step 1:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 16

Step 2:
When dividing 65 by 16, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 1 after subtracting 64 from 65.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 16

Step 3:
If we divide 18 by 16, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 41.0
If we take 16 away from 18, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 16

Going ahead to step 4:
27 divided by 16 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 411.0
If we subtract 16 from 27, we get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 16

Going ahead to step 5:
When dividing 112 by 16, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 4117.0
Deduct 112 from 112 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 16

Advancing to step 6:
If we divide 8 by 16, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 41170.0
If we take 0 away from 8, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 16

Moving on to step 7:
16 can be fit into 89 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 411705.0
If we subtract 80 from 89, we get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 16

Advancing to step 8:
91 divided by 16 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 4117055.0
If we take 80 away from 91, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
If we divide 110 by 16, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 4117055.6
If we subtract 96 from 110, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
When dividing 140 by 16, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 4117055.68
If we take 128 away from 140, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 4117055.687
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.

Going ahead to step 12:
If we divide 80 by 16, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 4117055.6875
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.

On to step 13:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4117055.6875
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.

Let's proceed to step 14:
If we divide 0 by 16, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4117055.6875
The remainder is 0 after subtracting 0 from 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 quotient of the division is 4117055.6875, and the remainder is 0.0.
