We're dividing 670942 by 99 
The aim is to understand the frequency of 99 in 670942.

Moving on to step 1:
6 divided by 99 is 0 with 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.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 99

On to step 2:
When dividing 67 by 99, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 99

Advancing to step 3:
If we divide 670 by 99, we get 6 and a remainder of 76.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 594 from 670, we get 76.
Bring next digit (9) of the dividend behind the 76 and repeat the process: 769 / 99

Moving on to step 4:
When dividing 769 by 99, we get 7 with a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtract 693 from 769 to get 76.
Fetch the next digit (4) from the dividend, attach it to 76 and continue: 764 / 99

Let's proceed to step 5:
99 can be fit into 764 7 times, resulting in a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 677.0
If we subtract 693 from 764, we get 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 99

Going ahead to step 6:
The number 99 fits into 712 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 6777.0
Subtract 693 from 712 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
If we divide 190 by 99, we get 1 and a remainder of 91.
The next digit of our result is 1. 
Result so far: 6777.1
The remainder is 91 after subtracting 99 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 8:
The number 99 fits into 910 9 times, leaving a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 6777.19
The remainder is 19 after subtracting 891 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
The number 99 fits into 190 1 times, leaving a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 6777.191
Subtracting 99 from 190 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 10:
99 can be fit into 910 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 6777.1919
Subtract 891 from 910 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
99 can be fit into 190 1 times, resulting in a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 6777.19191
Subtracting 99 from 190 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 12:
When dividing 910 by 99, we get 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 6777.191919
Subtract 891 from 910 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
99 goes into 190 1 times with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 6777.1919191
Deduct 99 from 190 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 14:
99 goes into 910 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 6777.19191919
The remainder is 19 after subtracting 891 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 6777.19191919, with a leftover of 1.9e-08.
