65553175 ÷ 399 
We're looking to find how many times 399 goes into 65553175.

Moving on to step 1:
The number 399 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 399

Moving on to step 2:
The number 399 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 399

Moving on to step 3:
The number 399 fits into 655 1 times, leaving a remainder of 256.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 399 away from 655, we end up with 256.
Include the next digit (5) from the dividend after 256, then repeat: 2565 / 399

On to step 4:
399 can be fit into 2565 6 times, resulting in a remainder of 171.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 2394 from 2565 and we're left with 171.
Take the next digit (3) from the dividend and append it to 171, then repeat: 1713 / 399

On to step 5:
1713 divided by 399 is 4 with a remainder of 117.
Write down 4 as next digit of the result. 
Result so far: 164.0
If we take 1596 away from 1713, we end up with 117.
Fetch the next digit (1) from the dividend, attach it to 117 and continue: 1171 / 399

Moving on to step 6:
The number 399 fits into 1171 2 times, leaving a remainder of 373.
The next digit of our result is 2. 
Result so far: 1642.0
Subtract 798 from 1171 to get 373.
Grab the next digit (7) from the dividend, add it to 373, then carry on: 3737 / 399

Advancing to step 7:
3737 divided by 399 is 9 with a remainder of 146.
Use 9 as the next digit of our solution. 
Result so far: 16429.0
Deduct 3591 from 3737 and we're left with 146.
Include the next digit (5) from the dividend after 146, then repeat: 1465 / 399

Let's proceed to step 8:
1465 divided by 399 is 3 with a remainder of 268.
Put 3 as the next digit of the answer. 
Result so far: 164293.0
Subtracting 1197 from 1465 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 9:
399 goes into 2680 6 times with a remainder of 286.
The next digit of our result is 6. 
Result so far: 164293.6
Deduct 2394 from 2680 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 10:
399 can be fit into 2860 7 times, resulting in a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 164293.67
Deduct 2793 from 2860 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 11:
The number 399 fits into 670 1 times, leaving a remainder of 271.
The number 1 becomes the next digit in our result. 
Result so far: 164293.671
If we subtract 399 from 670, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 12:
If we divide 2710 by 399, we get 6 and a remainder of 316.
Write down 6 as next digit of the result. 
Result so far: 164293.6716
Deduct 2394 from 2710 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 13:
The number 399 fits into 3160 7 times, leaving a remainder of 367.
Put 7 as the next digit of the answer. 
Result so far: 164293.67167
Subtracting 2793 from 3160 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 14:
3670 divided by 399 is 9 with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 164293.671679
Subtracting 3591 from 3670 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 15:
399 goes into 790 1 times with a remainder of 391.
Record the quotient 1 as the next digit in the result. 
Result so far: 164293.6716791
Deduct 399 from 790 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Going ahead to step 16:
If we divide 3910 by 399, we get 9 and a remainder of 319.
Put 9 as the next digit of the answer. 
Result so far: 164293.67167919
Subtract 3591 from 3910 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Our division results in 164293.67167919 with a remaining 3.19e-07.
