We look at the division of 12512020 by 192 
Our goal is to divide 12512020 by 192.

Going ahead to step 1:
192 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 192

Going ahead to step 2:
192 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 192

On to step 3:
125 divided by 192 is 0 with a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 125, we get 125.
Bring next digit (1) of the dividend behind the 125 and repeat the process: 1251 / 192

Going ahead to step 4:
192 goes into 1251 6 times with a remainder of 99.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 1152 away from 1251, we end up with 99.
Include the next digit (2) from the dividend after 99, then repeat: 992 / 192

Moving on to step 5:
The number 192 fits into 992 5 times, leaving a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 65.0
The remainder is 32 after subtracting 960 from 992.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 192

Advancing to step 6:
When dividing 320 by 192, we get 1 with a remainder of 128.
The number 1 becomes the next digit in our result. 
Result so far: 651.0
Subtracting 192 from 320 leaves us with 128.
Take the next digit (2) from the dividend and append it to 128, then repeat: 1282 / 192

Let's proceed to step 7:
192 can be fit into 1282 6 times, resulting in a remainder of 130.
Put 6 as the next digit of the answer. 
Result so far: 6516.0
The remainder is 130 after subtracting 1152 from 1282.
Append the next digit (0) from the dividend to 130 and continue with: 1300 / 192

On to step 8:
When dividing 1300 by 192, we get 6 with a remainder of 148.
The number 6 becomes the next digit in our result. 
Result so far: 65166.0
If we take 1152 away from 1300, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 9:
When dividing 1480 by 192, we get 7 with a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 65166.7
If we take 1344 away from 1480, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
192 can be fit into 1360 7 times, resulting in a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 65166.77
If we take 1344 away from 1360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 65166.77 and a remainder of 0.016.
