838172 divided by 88 
The aim is to understand the frequency of 88 in 838172.

Step 1:
8 divided by 88 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 88

Step 2:
88 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Fetch the next digit (8) from the dividend, attach it to 83 and continue: 838 / 88

Step 3:
When dividing 838 by 88, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 792 from 838 and we're left with 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 88

Advancing to step 4:
88 goes into 461 5 times with a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Deduct 440 from 461 and we're left with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 88

Let's proceed to step 5:
88 goes into 217 2 times with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 952.0
If we subtract 176 from 217, we get 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 88

Advancing to step 6:
If we divide 412 by 88, we get 4 and a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 9524.0
If we take 352 away from 412, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
88 can be fit into 600 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 9524.6
Subtract 528 from 600 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
88 can be fit into 720 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 9524.68
Subtracting 704 from 720 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
88 goes into 160 1 times with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 9524.681
Deduct 88 from 160 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
The number 88 fits into 720 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 9524.6818
The remainder is 16 after subtracting 704 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
The number 88 fits into 160 1 times, leaving a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 9524.68181
If we take 88 away from 160, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
88 can be fit into 720 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9524.681818
Deduct 704 from 720 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
88 goes into 160 1 times with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 9524.6818181
Subtract 88 from 160 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
88 goes into 720 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 9524.68181818
Deduct 704 from 720 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 9524.68181818 with a remainder of 1.6e-08.
