Let's divide 667597 by 99
The aim is to understand the frequency of 99 in 667597.

On to step 1:
99 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 99

Step 2:
99 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 99

Going ahead to step 3:
If we divide 667 by 99, we get 6 and a remainder of 73.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 594 from 667 leaves us with 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 99

Let's proceed to step 4:
99 can be fit into 735 7 times, resulting in a remainder of 42.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 693 from 735 leaves us with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 99

Moving on to step 5:
The number 99 fits into 429 4 times, leaving a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 674.0
Subtract 396 from 429 to get 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 99

Moving on to step 6:
The number 99 fits into 337 3 times, leaving a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 6743.0
Subtracting 297 from 337 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
400 divided by 99 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 6743.4
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
99 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6743.4
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 99 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 6743.404
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 99 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6743.404
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
400 divided by 99 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 6743.40404
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 99 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6743.40404
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
The number 99 fits into 400 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 6743.4040404
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
99 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6743.4040404
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 6743.4040404 with a remainder of 4e-08.
