We're dividing 16461090 by 609 
The aim is to understand the frequency of 609 in 16461090.

Going ahead to step 1:
609 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 609

Moving on to step 2:
The number 609 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 609

Moving on to step 3:
609 can be fit into 164 0 times, resulting in a remainder of 164.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 164 leaves us with 164.
Bring next digit (6) of the dividend behind the 164 and repeat the process: 1646 / 609

Advancing to step 4:
609 goes into 1646 2 times with a remainder of 428.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1218 away from 1646, we end up with 428.
Bring next digit (1) of the dividend behind the 428 and repeat the process: 4281 / 609

Let's proceed to step 5:
4281 divided by 609 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 27.0
The remainder is 18 after subtracting 4263 from 4281.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 609

Moving on to step 6:
609 goes into 180 0 times with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 270.0
Deduct 0 from 180 and we're left with 180.
Take the next digit (9) from the dividend and append it to 180, then repeat: 1809 / 609

On to step 7:
The number 609 fits into 1809 2 times, leaving a remainder of 591.
Write down 2 as next digit of the result. 
Result so far: 2702.0
Subtract 1218 from 1809 to get 591.
Fetch the next digit (0) from the dividend, attach it to 591 and continue: 5910 / 609

On to step 8:
When dividing 5910 by 609, we get 9 with a remainder of 429.
Put 9 as the next digit of the answer. 
Result so far: 27029.0
Subtract 5481 from 5910 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Moving on to step 9:
When dividing 4290 by 609, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 27029.7
If we take 4263 away from 4290, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
609 can be fit into 270 0 times, resulting in a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 27029.7
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 11:
609 goes into 2700 4 times with a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 27029.704
If we subtract 2436 from 2700, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 12:
609 goes into 2640 4 times with a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 27029.7044
Subtract 2436 from 2640 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final outcome is 27029.7044, with a leftover of 0.00204.
