Let's divide 10428461 by 609
The aim is to understand the frequency of 609 in 10428461.

Let's proceed to step 1:
1 divided by 609 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 609

Moving on to step 2:
10 divided by 609 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 609

Going ahead to step 3:
104 divided by 609 is 0 with a remainder of 104.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 104 leaves us with 104.
Grab the next digit (2) from the dividend, add it to 104, then carry on: 1042 / 609

Step 4:
609 can be fit into 1042 1 times, resulting in a remainder of 433.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 609 from 1042 and we're left with 433.
Bring next digit (8) of the dividend behind the 433 and repeat the process: 4338 / 609

Let's proceed to step 5:
609 can be fit into 4338 7 times, resulting in a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 4263 from 4338 to get 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 609

Advancing to step 6:
If we divide 754 by 609, we get 1 and a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
If we take 609 away from 754, we end up with 145.
Bring next digit (6) of the dividend behind the 145 and repeat the process: 1456 / 609

Let's proceed to step 7:
1456 divided by 609 is 2 with a remainder of 238.
Write down 2 as next digit of the result. 
Result so far: 1712.0
Subtracting 1218 from 1456 leaves us with 238.
Include the next digit (1) from the dividend after 238, then repeat: 2381 / 609

Let's proceed to step 8:
The number 609 fits into 2381 3 times, leaving a remainder of 554.
Use 3 as the next digit of our solution. 
Result so far: 17123.0
If we subtract 1827 from 2381, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 9:
609 can be fit into 5540 9 times, resulting in a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 17123.9
Deduct 5481 from 5540 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 10:
If we divide 590 by 609, we get 0 and a remainder of 590.
The number 0 becomes the next digit in our result. 
Result so far: 17123.9
Subtract 0 from 590 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 11:
609 goes into 5900 9 times with a remainder of 419.
Put 9 as the next digit of the answer. 
Result so far: 17123.909
If we take 5481 away from 5900, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Advancing to step 12:
The number 609 fits into 4190 6 times, leaving a remainder of 536.
Put 6 as the next digit of the answer. 
Result so far: 17123.9096
Deduct 3654 from 4190 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 13:
When dividing 5360 by 609, we get 8 with a remainder of 488.
The number 8 becomes the next digit in our result. 
Result so far: 17123.90968
The remainder is 488 after subtracting 4872 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 14:
If we divide 4880 by 609, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 17123.909688
The remainder is 8 after subtracting 4872 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 17123.909688, with a leftover of 8e-07.
