We're dividing 641136 by 16 
We want to divide 641136 by 16.

Advancing to step 1:
16 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 16

Going ahead to step 2:
16 goes into 64 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 64 from 64 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 16

Advancing to step 3:
If we divide 1 by 16, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 40.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 16

On to step 4:
11 divided by 16 is 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 16

Let's proceed to step 5:
The number 16 fits into 113 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 4007.0
Deduct 112 from 113 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 16

On to step 6:
The number 16 fits into 16 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 40071.0
Subtracting 16 from 16 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.

Going ahead to step 7:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40071.0
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.

Step 8:
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: 40071.0
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.

The final result is 40071.0 with a remainder of 0.0.
