We're dividing 891486 by 88 
The aim is to understand the frequency of 88 in 891486.

Moving on to step 1:
The number 88 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 88

Going ahead to step 2:
If we divide 89 by 88, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 88 from 89 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 88

Let's proceed to step 3:
The number 88 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 11 and we're left with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 88

Advancing to step 4:
114 divided by 88 is 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 88 from 114 and we're left with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 88

Moving on to step 5:
88 can be fit into 268 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 1013.0
Subtracting 264 from 268 leaves us with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 88

Step 6:
88 goes into 46 0 times with a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 10130.0
The remainder is 46 after subtracting 0 from 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
If we divide 460 by 88, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 10130.5
The remainder is 20 after subtracting 440 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
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: 10130.52
If we take 176 away from 200, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
88 can be fit into 240 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 10130.522
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.

Our division results in 10130.522 with a remaining 0.0064.
