15909 ÷ 67 
Our goal is to divide 15909 by 67.

Step 1:
If we divide 1 by 67, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 67

Going ahead to step 2:
When dividing 15 by 67, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 67

On to step 3:
If we divide 159 by 67, we get 2 and a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 134 from 159, we get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 67

Let's proceed to step 4:
250 divided by 67 is 3 with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 49 after subtracting 201 from 250.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 67

Let's proceed to step 5:
67 can be fit into 499 7 times, resulting in a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 237.0
Subtracting 469 from 499 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 6:
67 goes into 300 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 237.4
If we subtract 268 from 300, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
When dividing 320 by 67, we get 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 237.44
Subtracting 268 from 320 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 237.44 with a remainder of 0.052.
