72301098 ÷ 606 
The aim is to understand the frequency of 606 in 72301098.

Advancing to step 1:
The number 606 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 606

Going ahead to step 2:
606 can be fit into 72 0 times, resulting in a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (3) from the dividend and append it to 72, then repeat: 723 / 606

Let's proceed to step 3:
If we divide 723 by 606, we get 1 and a remainder of 117.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 606 away from 723, we end up with 117.
Include the next digit (0) from the dividend after 117, then repeat: 1170 / 606

Step 4:
606 goes into 1170 1 times with a remainder of 564.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 606 from 1170 to get 564.
Fetch the next digit (1) from the dividend, attach it to 564 and continue: 5641 / 606

Let's proceed to step 5:
The number 606 fits into 5641 9 times, leaving a remainder of 187.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Deduct 5454 from 5641 and we're left with 187.
Take the next digit (0) from the dividend and append it to 187, then repeat: 1870 / 606

Moving on to step 6:
If we divide 1870 by 606, we get 3 and a remainder of 52.
The next digit of our result is 3. 
Result so far: 1193.0
If we take 1818 away from 1870, we end up with 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 606

Let's proceed to step 7:
When dividing 529 by 606, we get 0 with a remainder of 529.
The number 0 becomes the next digit in our result. 
Result so far: 11930.0
Subtracting 0 from 529 leaves us with 529.
Include the next digit (8) from the dividend after 529, then repeat: 5298 / 606

Advancing to step 8:
606 goes into 5298 8 times with a remainder of 450.
Write down 8 as next digit of the result. 
Result so far: 119308.0
Subtracting 4848 from 5298 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 9:
606 can be fit into 4500 7 times, resulting in a remainder of 258.
Record the quotient 7 as the next digit in the result. 
Result so far: 119308.7
If we subtract 4242 from 4500, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 10:
When dividing 2580 by 606, we get 4 with a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 119308.74
Subtract 2424 from 2580 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
606 can be fit into 1560 2 times, resulting in a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 119308.742
If we subtract 1212 from 1560, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 12:
When dividing 3480 by 606, we get 5 with a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 119308.7425
If we take 3030 away from 3480, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 13:
The number 606 fits into 4500 7 times, leaving a remainder of 258.
Put 7 as the next digit of the answer. 
Result so far: 119308.74257
If we subtract 4242 from 4500, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 14:
The number 606 fits into 2580 4 times, leaving a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 119308.742574
If we subtract 2424 from 2580, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 15:
606 goes into 1560 2 times with a remainder of 348.
The next digit of our result is 2. 
Result so far: 119308.7425742
If we take 1212 away from 1560, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 16:
3480 divided by 606 is 5 with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 119308.74257425
If we take 3030 away from 3480, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

The final outcome is 119308.74257425, with a leftover of 4.5e-07.
