We divide 87139841 by 16
We're looking to find how many times 16 goes into 87139841.

Moving on to step 1:
When dividing 8 by 16, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 16

On to step 2:
When dividing 87 by 16, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 7 after subtracting 80 from 87.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 16

Moving on to step 3:
71 divided by 16 is 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 54.0
The remainder is 7 after subtracting 64 from 71.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 16

Let's proceed to step 4:
When dividing 73 by 16, we get 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 544.0
The remainder is 9 after subtracting 64 from 73.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 16

Moving on to step 5:
99 divided by 16 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 5446.0
The remainder is 3 after subtracting 96 from 99.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 16

Let's proceed to step 6:
16 can be fit into 38 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 54462.0
Deduct 32 from 38 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 16

Step 7:
When dividing 64 by 16, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 544624.0
Subtracting 64 from 64 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 16

Moving on to step 8:
16 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 5446240.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
16 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5446240.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
16 can be fit into 100 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 5446240.06
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
If we divide 40 by 16, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 5446240.062
If we subtract 32 from 40, 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.

Going ahead to step 12:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5446240.0625
The remainder is 0 after subtracting 80 from 80.
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 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5446240.0625
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.

Let's proceed to step 14:
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: 5446240.0625
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.

The final outcome is 5446240.0625, with a leftover of 0.0.
