69422674 divided by 88 
The aim is to understand the frequency of 88 in 69422674.

On to step 1:
6 divided by 88 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 88

Moving on to step 2:
If we divide 69 by 88, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Grab the next digit (4) from the dividend, add it to 69, then carry on: 694 / 88

Advancing to step 3:
If we divide 694 by 88, we get 7 and a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 616 from 694 to get 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 88

Going ahead to step 4:
If we divide 782 by 88, we get 8 and a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we subtract 704 from 782, we get 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 88

Moving on to step 5:
The number 88 fits into 782 8 times, leaving a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 788.0
Subtract 704 from 782 to get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 88

Step 6:
If we divide 786 by 88, we get 8 and a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 7888.0
Subtracting 704 from 786 leaves us with 82.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 88

Step 7:
If we divide 827 by 88, we get 9 and a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 78889.0
Subtract 792 from 827 to get 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 88

Going ahead to step 8:
88 goes into 354 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 788894.0
Subtract 352 from 354 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
When dividing 20 by 88, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 788894.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 88, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 788894.02
If we subtract 176 from 200, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
When dividing 240 by 88, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 788894.022
The remainder is 64 after subtracting 176 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 788894.022, with a leftover of 0.0064.
