We divide 23921 by 39
Let's see how many times 39 fits into 23921.

Let's proceed to step 1:
If we divide 2 by 39, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 39

Going ahead to step 2:
39 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 39

Advancing to step 3:
If we divide 239 by 39, we get 6 and a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 234 from 239 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 39

Let's proceed to step 4:
39 goes into 52 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we subtract 39 from 52, we get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 39

Advancing to step 5:
131 divided by 39 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 613.0
Subtract 117 from 131 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 6:
If we divide 140 by 39, we get 3 and a remainder of 23.
The next digit of our result is 3. 
Result so far: 613.3
Deduct 117 from 140 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
If we divide 230 by 39, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 613.35
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
350 divided by 39 is 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 613.358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
380 divided by 39 is 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 613.3589
If we subtract 351 from 380, we 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.

Let's proceed to step 10:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 613.35897
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.

Step 11:
The number 39 fits into 170 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 613.358974
Deduct 156 from 170 and we're left 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.

On to step 12:
140 divided by 39 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 613.3589743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
39 goes into 230 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 613.35897435
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 613.35897435 with a remainder of 3.5e-08.
