Let's divide 1279057 by 661
The aim is to understand the frequency of 661 in 1279057.

Moving on to step 1:
661 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 661

Step 2:
The number 661 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 661

Advancing to step 3:
If we divide 127 by 661, we get 0 and a remainder of 127.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 127, we get 127.
Grab the next digit (9) from the dividend, add it to 127, then carry on: 1279 / 661

On to step 4:
661 goes into 1279 1 times with a remainder of 618.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 661 from 1279 leaves us with 618.
Bring next digit (0) of the dividend behind the 618 and repeat the process: 6180 / 661

Advancing to step 5:
If we divide 6180 by 661, we get 9 and a remainder of 231.
The next digit of our result is 9. 
Result so far: 19.0
If we take 5949 away from 6180, we end up with 231.
Bring next digit (5) of the dividend behind the 231 and repeat the process: 2315 / 661

Let's proceed to step 6:
The number 661 fits into 2315 3 times, leaving a remainder of 332.
Write down 3 as next digit of the result. 
Result so far: 193.0
Subtract 1983 from 2315 to get 332.
Bring next digit (7) of the dividend behind the 332 and repeat the process: 3327 / 661

Step 7:
When dividing 3327 by 661, we get 5 with a remainder of 22.
The next digit of our result is 5. 
Result so far: 1935.0
The remainder is 22 after subtracting 3305 from 3327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
If we divide 220 by 661, we get 0 and a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 1935.0
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 9:
If we divide 2200 by 661, we get 3 and a remainder of 217.
Put 3 as the next digit of the answer. 
Result so far: 1935.03
The remainder is 217 after subtracting 1983 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 10:
2170 divided by 661 is 3 with a remainder of 187.
Use 3 as the next digit of our solution. 
Result so far: 1935.033
Deduct 1983 from 2170 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

The final result is 1935.033 with a remainder of 0.0187.
