12012065 ÷ 625 
The aim is to understand the frequency of 625 in 12012065.

On to step 1:
When dividing 1 by 625, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 625

Step 2:
The number 625 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 625

Let's proceed to step 3:
120 divided by 625 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 120 to get 120.
Append the next digit (1) from the dividend to 120 and continue with: 1201 / 625

Moving on to step 4:
1201 divided by 625 is 1 with a remainder of 576.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 625 away from 1201, we end up with 576.
Grab the next digit (2) from the dividend, add it to 576, then carry on: 5762 / 625

On to step 5:
The number 625 fits into 5762 9 times, leaving a remainder of 137.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 5625 away from 5762, we end up with 137.
Append the next digit (0) from the dividend to 137 and continue with: 1370 / 625

Step 6:
625 can be fit into 1370 2 times, resulting in a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 192.0
The remainder is 120 after subtracting 1250 from 1370.
Include the next digit (6) from the dividend after 120, then repeat: 1206 / 625

On to step 7:
1206 divided by 625 is 1 with a remainder of 581.
The next digit of our result is 1. 
Result so far: 1921.0
Subtracting 625 from 1206 leaves us with 581.
Bring next digit (5) of the dividend behind the 581 and repeat the process: 5815 / 625

Step 8:
625 can be fit into 5815 9 times, resulting in a remainder of 190.
Use 9 as the next digit of our solution. 
Result so far: 19219.0
Subtract 5625 from 5815 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 9:
625 can be fit into 1900 3 times, resulting in a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 19219.3
The remainder is 25 after subtracting 1875 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
If we divide 250 by 625, we get 0 and a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 19219.3
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
The number 625 fits into 2500 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 19219.304
Subtracting 2500 from 2500 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
If we divide 0 by 625, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19219.304
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
The number 625 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19219.304
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 19219.304 and a remainder of 0.0.
