81188668 divided by 352 
The aim is to understand the frequency of 352 in 81188668.

Step 1:
352 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 352

Let's proceed to step 2:
If we divide 81 by 352, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 352

Let's proceed to step 3:
811 divided by 352 is 2 with a remainder of 107.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 107 after subtracting 704 from 811.
Fetch the next digit (8) from the dividend, attach it to 107 and continue: 1078 / 352

Advancing to step 4:
352 goes into 1078 3 times with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 1056 from 1078 and we're left with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 352

Going ahead to step 5:
If we divide 228 by 352, we get 0 and a remainder of 228.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
Subtracting 0 from 228 leaves us with 228.
Bring next digit (6) of the dividend behind the 228 and repeat the process: 2286 / 352

On to step 6:
If we divide 2286 by 352, we get 6 and a remainder of 174.
Put 6 as the next digit of the answer. 
Result so far: 2306.0
Deduct 2112 from 2286 and we're left with 174.
Include the next digit (6) from the dividend after 174, then repeat: 1746 / 352

On to step 7:
The number 352 fits into 1746 4 times, leaving a remainder of 338.
Record the quotient 4 as the next digit in the result. 
Result so far: 23064.0
If we subtract 1408 from 1746, we get 338.
Bring next digit (8) of the dividend behind the 338 and repeat the process: 3388 / 352

Advancing to step 8:
The number 352 fits into 3388 9 times, leaving a remainder of 220.
The next digit of our result is 9. 
Result so far: 230649.0
If we take 3168 away from 3388, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 9:
When dividing 2200 by 352, we get 6 with a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 230649.6
Subtract 2112 from 2200 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
880 divided by 352 is 2 with a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 230649.62
Subtract 704 from 880 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 11:
352 can be fit into 1760 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 230649.625
Deduct 1760 from 1760 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
When dividing 0 by 352, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 230649.625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
0 divided by 352 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 230649.625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 230649.625 with a remainder of 0.0.
