We're dividing 6194965 by 661 
The aim is to understand the frequency of 661 in 6194965.

Advancing to step 1:
The number 661 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 661

Step 2:
If we divide 61 by 661, we get 0 and a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Fetch the next digit (9) from the dividend, attach it to 61 and continue: 619 / 661

Step 3:
When dividing 619 by 661, we get 0 with a remainder of 619.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 619 to get 619.
Bring next digit (4) of the dividend behind the 619 and repeat the process: 6194 / 661

Going ahead to step 4:
661 goes into 6194 9 times with a remainder of 245.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 5949 away from 6194, we end up with 245.
Bring next digit (9) of the dividend behind the 245 and repeat the process: 2459 / 661

Step 5:
661 goes into 2459 3 times with a remainder of 476.
Put 3 as the next digit of the answer. 
Result so far: 93.0
The remainder is 476 after subtracting 1983 from 2459.
Append the next digit (6) from the dividend to 476 and continue with: 4766 / 661

Advancing to step 6:
4766 divided by 661 is 7 with a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 937.0
Deduct 4627 from 4766 and we're left with 139.
Bring next digit (5) of the dividend behind the 139 and repeat the process: 1395 / 661

Moving on to step 7:
The number 661 fits into 1395 2 times, leaving a remainder of 73.
Use 2 as the next digit of our solution. 
Result so far: 9372.0
The remainder is 73 after subtracting 1322 from 1395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 8:
If we divide 730 by 661, we get 1 and a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 9372.1
Subtracting 661 from 730 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
If we divide 690 by 661, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 9372.11
Subtracting 661 from 690 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 9372.11, and the remainder is 0.029.
