We look at the division of 336669 by 80 
We want to divide 336669 by 80.

Advancing to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 80

Let's proceed to step 2:
When dividing 33 by 80, we get 0 with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 80

Step 3:
336 divided by 80 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 320 from 336 to get 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 80

Going ahead to step 4:
80 can be fit into 166 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 160 from 166 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 80

On to step 5:
The number 80 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 80

On to step 6:
If we divide 669 by 80, we get 8 and a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 4208.0
Subtract 640 from 669 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
When dividing 290 by 80, we get 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 4208.3
Deduct 240 from 290 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
80 goes into 500 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 4208.36
Subtracting 480 from 500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 4208.362
If we take 160 away from 200, we end up 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.

Going ahead to step 10:
400 divided by 80 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4208.3625
Deduct 400 from 400 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 11:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4208.3625
Subtract 0 from 0 to 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.

Advancing to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4208.3625
Subtracting 0 from 0 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.

Our division results in 4208.3625 with a remaining 0.0.
