We're dividing 16209 by 74 
We're looking to find how many times 74 goes into 16209.

Step 1:
When dividing 1 by 74, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 74

On to step 2:
74 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 74

Advancing to step 3:
When dividing 162 by 74, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 148 from 162 to get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 74

On to step 4:
When dividing 140 by 74, we get 1 with a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 74 from 140, we get 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 74

Moving on to step 5:
669 divided by 74 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 219.0
If we subtract 666 from 669, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 6:
30 divided by 74 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 219.0
If we take 0 away from 30, we end up 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.

Moving on to step 7:
When dividing 300 by 74, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 219.04
Deduct 296 from 300 and we're left 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.

Moving on to step 8:
When dividing 40 by 74, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 219.04
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 74 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 219.0405
The remainder is 30 after subtracting 370 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
74 goes into 300 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 219.04054
The remainder is 4 after subtracting 296 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
When dividing 40 by 74, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 219.04054
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
74 goes into 400 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 219.0405405
If we take 370 away from 400, we end up 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.

Moving on to step 13:
74 can be fit into 300 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 219.04054054
Subtracting 296 from 300 leaves us 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.

The final result is 219.04054054 with a remainder of 4e-09.
