We're dividing 1275075 by 651 
The aim is to understand the frequency of 651 in 1275075.

Let's proceed to step 1:
1 divided by 651 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
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 / 651

Let's proceed to step 2:
651 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 651

On to step 3:
The number 651 fits into 127 0 times, leaving a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 127 and we're left with 127.
Take the next digit (5) from the dividend and append it to 127, then repeat: 1275 / 651

Step 4:
1275 divided by 651 is 1 with a remainder of 624.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 651 from 1275, we get 624.
Append the next digit (0) from the dividend to 624 and continue with: 6240 / 651

Going ahead to step 5:
If we divide 6240 by 651, we get 9 and a remainder of 381.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 5859 from 6240 leaves us with 381.
Bring next digit (7) of the dividend behind the 381 and repeat the process: 3817 / 651

Step 6:
If we divide 3817 by 651, we get 5 and a remainder of 562.
Write down 5 as next digit of the result. 
Result so far: 195.0
The remainder is 562 after subtracting 3255 from 3817.
Take the next digit (5) from the dividend and append it to 562, then repeat: 5625 / 651

Moving on to step 7:
5625 divided by 651 is 8 with a remainder of 417.
Write down 8 as next digit of the result. 
Result so far: 1958.0
Subtract 5208 from 5625 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Advancing to step 8:
4170 divided by 651 is 6 with a remainder of 264.
Record the quotient 6 as the next digit in the result. 
Result so far: 1958.6
If we take 3906 away from 4170, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 9:
The number 651 fits into 2640 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 1958.64
Subtract 2604 from 2640 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
360 divided by 651 is 0 with a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 1958.64
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 11:
651 can be fit into 3600 5 times, resulting in a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 1958.6405
If we take 3255 away from 3600, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Going ahead to step 12:
The number 651 fits into 3450 5 times, leaving a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 1958.64055
If we subtract 3255 from 3450, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final result is 1958.64055 with a remainder of 0.000195.
