55590695 divided by 388 
The aim is to understand the frequency of 388 in 55590695.

Step 1:
5 divided by 388 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 388

Let's proceed to step 2:
When dividing 55 by 388, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 388

Moving on to step 3:
388 goes into 555 1 times with a remainder of 167.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 388 from 555 and we're left with 167.
Grab the next digit (9) from the dividend, add it to 167, then carry on: 1679 / 388

Going ahead to step 4:
The number 388 fits into 1679 4 times, leaving a remainder of 127.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 1552 from 1679 and we're left with 127.
Include the next digit (0) from the dividend after 127, then repeat: 1270 / 388

Step 5:
The number 388 fits into 1270 3 times, leaving a remainder of 106.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
The remainder is 106 after subtracting 1164 from 1270.
Bring next digit (6) of the dividend behind the 106 and repeat the process: 1066 / 388

On to step 6:
If we divide 1066 by 388, we get 2 and a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 1432.0
Subtract 776 from 1066 to get 290.
Grab the next digit (9) from the dividend, add it to 290, then carry on: 2909 / 388

On to step 7:
If we divide 2909 by 388, we get 7 and a remainder of 193.
The next digit of our result is 7. 
Result so far: 14327.0
The remainder is 193 after subtracting 2716 from 2909.
Grab the next digit (5) from the dividend, add it to 193, then carry on: 1935 / 388

Step 8:
1935 divided by 388 is 4 with a remainder of 383.
The next digit of our result is 4. 
Result so far: 143274.0
If we subtract 1552 from 1935, we get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

On to step 9:
388 can be fit into 3830 9 times, resulting in a remainder of 338.
Record the quotient 9 as the next digit in the result. 
Result so far: 143274.9
Deduct 3492 from 3830 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 10:
The number 388 fits into 3380 8 times, leaving a remainder of 276.
Record the quotient 8 as the next digit in the result. 
Result so far: 143274.98
If we take 3104 away from 3380, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 11:
When dividing 2760 by 388, we get 7 with a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 143274.987
The remainder is 44 after subtracting 2716 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
When dividing 440 by 388, we get 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 143274.9871
The remainder is 52 after subtracting 388 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
The number 388 fits into 520 1 times, leaving a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 143274.98711
If we subtract 388 from 520, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 143274.98711, with a leftover of 0.000132.
