We're dividing 12620164 by 125 
The aim is to understand the frequency of 125 in 12620164.

Step 1:
1 divided by 125 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 125

Advancing to step 2:
If we divide 12 by 125, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 125

Step 3:
The number 125 fits into 126 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 125 from 126 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 125

Advancing to step 4:
12 divided by 125 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 125

Moving on to step 5:
125 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 100.0
The remainder is 120 after subtracting 0 from 120.
Take the next digit (1) from the dividend and append it to 120, then repeat: 1201 / 125

Let's proceed to step 6:
The number 125 fits into 1201 9 times, leaving a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 1009.0
Subtract 1125 from 1201 to get 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 125

On to step 7:
When dividing 766 by 125, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 10096.0
If we take 750 away from 766, we end up with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 125

Moving on to step 8:
164 divided by 125 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 100961.0
If we subtract 125 from 164, we 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.

Step 9:
The number 125 fits into 390 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 100961.3
Subtract 375 from 390 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
125 goes into 150 1 times with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 100961.31
Subtract 125 from 150 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
When dividing 250 by 125, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 100961.312
Subtracting 250 from 250 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.

Step 12:
If we divide 0 by 125, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 100961.312
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.

On to step 13:
The number 125 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 100961.312
Subtract 0 from 0 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.

The quotient of the division is 100961.312, and the remainder is 0.0.
