69377 ÷ 99 
The aim is to understand the frequency of 99 in 69377.

Moving on to step 1:
99 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 99

Advancing to step 2:
The number 99 fits into 69 0 times, leaving a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 99

On to step 3:
693 divided by 99 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 693 from 693 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 99

On to step 4:
When dividing 7 by 99, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 70.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 99

On to step 5:
The number 99 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 700.0
If we take 0 away from 77, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 6:
If we divide 770 by 99, we get 7 and a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 700.7
The remainder is 77 after subtracting 693 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 7:
If we divide 770 by 99, we get 7 and a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 700.77
If we subtract 693 from 770, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final result is 700.77 with a remainder of 0.077.
