We're dividing 88215475 by 386 
The aim is to understand the frequency of 386 in 88215475.

Going ahead to step 1:
If we divide 8 by 386, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 386

Let's proceed to step 2:
The number 386 fits into 88 0 times, leaving a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Grab the next digit (2) from the dividend, add it to 88, then carry on: 882 / 386

On to step 3:
386 can be fit into 882 2 times, resulting in a remainder of 110.
The next digit of our result is 2. 
Result so far: 2.0
If we take 772 away from 882, we end up with 110.
Grab the next digit (1) from the dividend, add it to 110, then carry on: 1101 / 386

Going ahead to step 4:
1101 divided by 386 is 2 with a remainder of 329.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 772 from 1101, we get 329.
Grab the next digit (5) from the dividend, add it to 329, then carry on: 3295 / 386

Advancing to step 5:
When dividing 3295 by 386, we get 8 with a remainder of 207.
Put 8 as the next digit of the answer. 
Result so far: 228.0
Subtract 3088 from 3295 to get 207.
Fetch the next digit (4) from the dividend, attach it to 207 and continue: 2074 / 386

Advancing to step 6:
2074 divided by 386 is 5 with a remainder of 144.
The number 5 becomes the next digit in our result. 
Result so far: 2285.0
If we subtract 1930 from 2074, we get 144.
Append the next digit (7) from the dividend to 144 and continue with: 1447 / 386

On to step 7:
386 goes into 1447 3 times with a remainder of 289.
Record the quotient 3 as the next digit in the result. 
Result so far: 22853.0
If we take 1158 away from 1447, we end up with 289.
Fetch the next digit (5) from the dividend, attach it to 289 and continue: 2895 / 386

Advancing to step 8:
2895 divided by 386 is 7 with a remainder of 193.
Write down 7 as next digit of the result. 
Result so far: 228537.0
If we subtract 2702 from 2895, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 9:
The number 386 fits into 1930 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 228537.5
If we take 1930 away from 1930, 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.

Let's proceed to step 10:
When dividing 0 by 386, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 228537.5
Subtract 0 from 0 to 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.

On to step 11:
0 divided by 386 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 228537.5
Deduct 0 from 0 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.

The final result is 228537.5 with a remainder of 0.0.
