We're dividing 91680640 by 388 
The aim is to understand the frequency of 388 in 91680640.

Going ahead to step 1:
The number 388 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 388

Advancing to step 2:
91 divided by 388 is 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (6) from the dividend after 91, then repeat: 916 / 388

Let's proceed to step 3:
When dividing 916 by 388, we get 2 with a remainder of 140.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 776 from 916 leaves us with 140.
Include the next digit (8) from the dividend after 140, then repeat: 1408 / 388

On to step 4:
388 can be fit into 1408 3 times, resulting in a remainder of 244.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 1164 from 1408 and we're left with 244.
Fetch the next digit (0) from the dividend, attach it to 244 and continue: 2440 / 388

Let's proceed to step 5:
388 can be fit into 2440 6 times, resulting in a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 236.0
The remainder is 112 after subtracting 2328 from 2440.
Append the next digit (6) from the dividend to 112 and continue with: 1126 / 388

Advancing to step 6:
388 goes into 1126 2 times with a remainder of 350.
Write down 2 as next digit of the result. 
Result so far: 2362.0
Deduct 776 from 1126 and we're left with 350.
Append the next digit (4) from the dividend to 350 and continue with: 3504 / 388

Moving on to step 7:
388 goes into 3504 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 23629.0
Subtract 3492 from 3504 to get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 388

Moving on to step 8:
When dividing 120 by 388, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 236290.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 9:
The number 388 fits into 1200 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 236290.3
The remainder is 36 after subtracting 1164 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
When dividing 360 by 388, we get 0 with a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 236290.3
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
388 goes into 3600 9 times with a remainder of 108.
Write down 9 as next digit of the result. 
Result so far: 236290.309
If we subtract 3492 from 3600, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
If we divide 1080 by 388, we get 2 and a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 236290.3092
Subtract 776 from 1080 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 13:
3040 divided by 388 is 7 with a remainder of 324.
The next digit of our result is 7. 
Result so far: 236290.30927
The remainder is 324 after subtracting 2716 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 14:
When dividing 3240 by 388, we get 8 with a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 236290.309278
Subtract 3104 from 3240 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 15:
The number 388 fits into 1360 3 times, leaving a remainder of 196.
Record the quotient 3 as the next digit in the result. 
Result so far: 236290.3092783
If we take 1164 away from 1360, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 16:
1960 divided by 388 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 236290.30927835
If we take 1940 away from 1960, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 236290.30927835 with a remaining 2e-08.
