669633 ÷ 88 
The aim is to understand the frequency of 88 in 669633.

On to step 1:
When dividing 6 by 88, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 88

Moving on to step 2:
88 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 88

Advancing to step 3:
When dividing 669 by 88, we get 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 616 from 669 and we're left with 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 88

Going ahead to step 4:
The number 88 fits into 536 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we subtract 528 from 536, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 88

Moving on to step 5:
83 divided by 88 is 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 760.0
Subtract 0 from 83 to get 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 88

Moving on to step 6:
The number 88 fits into 833 9 times, leaving a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 7609.0
The remainder is 41 after subtracting 792 from 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
410 divided by 88 is 4 with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 7609.4
If we take 352 away from 410, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
88 can be fit into 580 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 7609.46
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
When dividing 520 by 88, we get 5 with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 7609.465
The remainder is 80 after subtracting 440 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
When dividing 800 by 88, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 7609.4659
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
88 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 7609.4659
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
88 goes into 800 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 7609.465909
Deduct 792 from 800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
88 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 7609.465909
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
When dividing 800 by 88, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 7609.46590909
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 7609.46590909, and the remainder is 8e-09.
