We're dividing 15660100 by 512 
We want to figure out the number of times 15660100 can be divided by 512.

Going ahead to step 1:
When dividing 1 by 512, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 512

Advancing to step 2:
When dividing 15 by 512, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 512

Advancing to step 3:
When dividing 156 by 512, we get 0 with a remainder of 156.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 156, we get 156.
Grab the next digit (6) from the dividend, add it to 156, then carry on: 1566 / 512

Let's proceed to step 4:
1566 divided by 512 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1536 away from 1566, we end up with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 512

On to step 5:
The number 512 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 30.0
If we take 0 away from 300, we end up with 300.
Grab the next digit (1) from the dividend, add it to 300, then carry on: 3001 / 512

Advancing to step 6:
512 can be fit into 3001 5 times, resulting in a remainder of 441.
The number 5 becomes the next digit in our result. 
Result so far: 305.0
If we subtract 2560 from 3001, we get 441.
Grab the next digit (0) from the dividend, add it to 441, then carry on: 4410 / 512

Step 7:
4410 divided by 512 is 8 with a remainder of 314.
Put 8 as the next digit of the answer. 
Result so far: 3058.0
The remainder is 314 after subtracting 4096 from 4410.
Take the next digit (0) from the dividend and append it to 314, then repeat: 3140 / 512

Going ahead to step 8:
If we divide 3140 by 512, we get 6 and a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 30586.0
The remainder is 68 after subtracting 3072 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
680 divided by 512 is 1 with a remainder of 168.
The next digit of our result is 1. 
Result so far: 30586.1
Subtracting 512 from 680 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 10:
When dividing 1680 by 512, we get 3 with a remainder of 144.
Record the quotient 3 as the next digit in the result. 
Result so far: 30586.13
The remainder is 144 after subtracting 1536 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
1440 divided by 512 is 2 with a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 30586.132
Subtract 1024 from 1440 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 12:
512 can be fit into 4160 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 30586.1328
If we take 4096 away from 4160, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
512 can be fit into 640 1 times, resulting in a remainder of 128.
The number 1 becomes the next digit in our result. 
Result so far: 30586.13281
Subtract 512 from 640 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 14:
1280 divided by 512 is 2 with a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 30586.132812
Deduct 1024 from 1280 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 15:
512 goes into 2560 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 30586.1328125
Subtract 2560 from 2560 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 16:
512 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30586.1328125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 30586.1328125 with a remaining 0.0.
