We're dividing 65364053 by 399 
Let's see how many times 399 fits into 65364053.

Going ahead to step 1:
399 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 399

Moving on to step 2:
If we divide 65 by 399, we get 0 and a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 399

Step 3:
399 goes into 653 1 times with a remainder of 254.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 254 after subtracting 399 from 653.
Append the next digit (6) from the dividend to 254 and continue with: 2546 / 399

Step 4:
399 goes into 2546 6 times with a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 2394 from 2546 leaves us with 152.
Grab the next digit (4) from the dividend, add it to 152, then carry on: 1524 / 399

Let's proceed to step 5:
The number 399 fits into 1524 3 times, leaving a remainder of 327.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
If we subtract 1197 from 1524, we get 327.
Bring next digit (0) of the dividend behind the 327 and repeat the process: 3270 / 399

On to step 6:
399 goes into 3270 8 times with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 1638.0
If we subtract 3192 from 3270, we get 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 399

Going ahead to step 7:
399 goes into 785 1 times with a remainder of 386.
The next digit of our result is 1. 
Result so far: 16381.0
If we take 399 away from 785, we end up with 386.
Bring next digit (3) of the dividend behind the 386 and repeat the process: 3863 / 399

Let's proceed to step 8:
399 goes into 3863 9 times with a remainder of 272.
The next digit of our result is 9. 
Result so far: 163819.0
Deduct 3591 from 3863 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 9:
If we divide 2720 by 399, we get 6 and a remainder of 326.
The number 6 becomes the next digit in our result. 
Result so far: 163819.6
If we take 2394 away from 2720, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 10:
3260 divided by 399 is 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 163819.68
Subtract 3192 from 3260 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
399 can be fit into 680 1 times, resulting in a remainder of 281.
Use 1 as the next digit of our solution. 
Result so far: 163819.681
Subtract 399 from 680 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 12:
If we divide 2810 by 399, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 163819.6817
The remainder is 17 after subtracting 2793 from 2810.
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 13:
When dividing 170 by 399, we get 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 163819.6817
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 14:
When dividing 1700 by 399, we get 4 with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 163819.681704
Subtracting 1596 from 1700 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 15:
When dividing 1040 by 399, we get 2 with a remainder of 242.
Put 2 as the next digit of the answer. 
Result so far: 163819.6817042
Deduct 798 from 1040 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 16:
If we divide 2420 by 399, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 163819.68170426
The remainder is 26 after subtracting 2394 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 163819.68170426 with a remainder of 2.6e-08.
