We're dividing 66164754 by 513 
We're looking to find how many times 513 goes into 66164754.

Going ahead to step 1:
513 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 513

Moving on to step 2:
The number 513 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 513

Advancing to step 3:
The number 513 fits into 661 1 times, leaving a remainder of 148.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 513 from 661 to get 148.
Grab the next digit (6) from the dividend, add it to 148, then carry on: 1486 / 513

Let's proceed to step 4:
1486 divided by 513 is 2 with a remainder of 460.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1026 from 1486, we get 460.
Include the next digit (4) from the dividend after 460, then repeat: 4604 / 513

Step 5:
The number 513 fits into 4604 8 times, leaving a remainder of 500.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtract 4104 from 4604 to get 500.
Take the next digit (7) from the dividend and append it to 500, then repeat: 5007 / 513

On to step 6:
5007 divided by 513 is 9 with a remainder of 390.
The next digit of our result is 9. 
Result so far: 1289.0
Subtracting 4617 from 5007 leaves us with 390.
Grab the next digit (5) from the dividend, add it to 390, then carry on: 3905 / 513

Step 7:
513 can be fit into 3905 7 times, resulting in a remainder of 314.
Put 7 as the next digit of the answer. 
Result so far: 12897.0
The remainder is 314 after subtracting 3591 from 3905.
Fetch the next digit (4) from the dividend, attach it to 314 and continue: 3144 / 513

Moving on to step 8:
513 goes into 3144 6 times with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 128976.0
If we take 3078 away from 3144, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
When dividing 660 by 513, we get 1 with a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 128976.1
The remainder is 147 after subtracting 513 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 10:
1470 divided by 513 is 2 with a remainder of 444.
The next digit of our result is 2. 
Result so far: 128976.12
Subtract 1026 from 1470 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 11:
If we divide 4440 by 513, we get 8 and a remainder of 336.
The number 8 becomes the next digit in our result. 
Result so far: 128976.128
The remainder is 336 after subtracting 4104 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 12:
513 can be fit into 3360 6 times, resulting in a remainder of 282.
Record the quotient 6 as the next digit in the result. 
Result so far: 128976.1286
The remainder is 282 after subtracting 3078 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 13:
513 can be fit into 2820 5 times, resulting in a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 128976.12865
Subtract 2565 from 2820 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 14:
513 goes into 2550 4 times with a remainder of 498.
Write down 4 as next digit of the result. 
Result so far: 128976.128654
Subtract 2052 from 2550 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 15:
4980 divided by 513 is 9 with a remainder of 363.
Use 9 as the next digit of our solution. 
Result so far: 128976.1286549
Deduct 4617 from 4980 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 16:
513 goes into 3630 7 times with a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 128976.12865497
Subtract 3591 from 3630 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 128976.12865497, with a leftover of 3.9e-08.
