We're dividing 16604 by 39 
We're looking to find how many times 39 goes into 16604.

Advancing to step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 39

Step 2:
39 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 39

Let's proceed to step 3:
166 divided by 39 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 156 from 166 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 39

Advancing to step 4:
100 divided by 39 is 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 78 from 100 leaves us with 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 39

Advancing to step 5:
If we divide 224 by 39, we get 5 and a remainder of 29.
The next digit of our result is 5. 
Result so far: 425.0
The remainder is 29 after subtracting 195 from 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 6:
When dividing 290 by 39, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 425.7
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
When dividing 170 by 39, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 425.74
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 39 fits into 140 3 times, leaving a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 425.743
If we subtract 117 from 140, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
When dividing 230 by 39, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 425.7435
Subtract 195 from 230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
350 divided by 39 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 425.74358
If we take 312 away from 350, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
If we divide 380 by 39, we get 9 and a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 425.743589
Deduct 351 from 380 and we're left with 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 12:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 425.7435897
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
If we divide 170 by 39, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 425.74358974
Subtracting 156 from 170 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 425.74358974 and a remainder of 1.4e-08.
