858186 ÷ 88 
The aim is to understand the frequency of 88 in 858186.

On to step 1:
When dividing 8 by 88, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 88

Going ahead to step 2:
88 can be fit into 85 0 times, resulting in a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (8) from the dividend, add it to 85, then carry on: 858 / 88

Step 3:
88 can be fit into 858 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 792 away from 858, we end up with 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 88

Moving on to step 4:
If we divide 661 by 88, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Deduct 616 from 661 and we're left with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 88

Moving on to step 5:
88 goes into 458 5 times with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 975.0
If we take 440 away from 458, we end up with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 88

Step 6:
When dividing 186 by 88, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 9752.0
If we take 176 away from 186, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
88 can be fit into 100 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 9752.1
Deduct 88 from 100 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
The number 88 fits into 120 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 9752.11
The remainder is 32 after subtracting 88 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 9752.11, and the remainder is 0.032.
