99340875 ÷ 609 
The aim is to understand the frequency of 609 in 99340875.

Let's proceed to step 1:
609 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 609

Step 2:
If we divide 99 by 609, we get 0 and a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 609

Going ahead to step 3:
The number 609 fits into 993 1 times, leaving a remainder of 384.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 384 after subtracting 609 from 993.
Include the next digit (4) from the dividend after 384, then repeat: 3844 / 609

Moving on to step 4:
3844 divided by 609 is 6 with a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 3654 from 3844 and we're left with 190.
Grab the next digit (0) from the dividend, add it to 190, then carry on: 1900 / 609

Moving on to step 5:
609 goes into 1900 3 times with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
The remainder is 73 after subtracting 1827 from 1900.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 609

Moving on to step 6:
When dividing 738 by 609, we get 1 with a remainder of 129.
Use 1 as the next digit of our solution. 
Result so far: 1631.0
If we subtract 609 from 738, we get 129.
Bring next digit (7) of the dividend behind the 129 and repeat the process: 1297 / 609

Moving on to step 7:
If we divide 1297 by 609, we get 2 and a remainder of 79.
Record the quotient 2 as the next digit in the result. 
Result so far: 16312.0
If we subtract 1218 from 1297, we get 79.
Append the next digit (5) from the dividend to 79 and continue with: 795 / 609

Step 8:
The number 609 fits into 795 1 times, leaving a remainder of 186.
Use 1 as the next digit of our solution. 
Result so far: 163121.0
Subtracting 609 from 795 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
1860 divided by 609 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 163121.3
If we subtract 1827 from 1860, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
When dividing 330 by 609, we get 0 with a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 163121.3
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 11:
When dividing 3300 by 609, we get 5 with a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 163121.305
If we subtract 3045 from 3300, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 12:
The number 609 fits into 2550 4 times, leaving a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 163121.3054
Deduct 2436 from 2550 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 13:
The number 609 fits into 1140 1 times, leaving a remainder of 531.
The number 1 becomes the next digit in our result. 
Result so far: 163121.30541
The remainder is 531 after subtracting 609 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 14:
The number 609 fits into 5310 8 times, leaving a remainder of 438.
The number 8 becomes the next digit in our result. 
Result so far: 163121.305418
Subtracting 4872 from 5310 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 15:
The number 609 fits into 4380 7 times, leaving a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 163121.3054187
Subtract 4263 from 4380 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 16:
When dividing 1170 by 609, we get 1 with a remainder of 561.
Put 1 as the next digit of the answer. 
Result so far: 163121.30541871
The remainder is 561 after subtracting 609 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

After the division, we end up with 163121.30541871 and a remainder of 5.61e-07.
