We divide 55550392 by 388
The aim is to understand the frequency of 388 in 55550392.

Step 1:
The number 388 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 388

Moving on to step 2:
When dividing 55 by 388, we get 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 388

Step 3:
388 goes into 555 1 times with a remainder of 167.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 167 after subtracting 388 from 555.
Take the next digit (5) from the dividend and append it to 167, then repeat: 1675 / 388

Going ahead to step 4:
If we divide 1675 by 388, we get 4 and a remainder of 123.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1552 from 1675 leaves us with 123.
Append the next digit (0) from the dividend to 123 and continue with: 1230 / 388

On to step 5:
1230 divided by 388 is 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we subtract 1164 from 1230, we get 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 388

Let's proceed to step 6:
If we divide 663 by 388, we get 1 and a remainder of 275.
The next digit of our result is 1. 
Result so far: 1431.0
Subtract 388 from 663 to get 275.
Include the next digit (9) from the dividend after 275, then repeat: 2759 / 388

Advancing to step 7:
If we divide 2759 by 388, we get 7 and a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 14317.0
If we subtract 2716 from 2759, we get 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 388

Advancing to step 8:
388 goes into 432 1 times with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 143171.0
If we subtract 388 from 432, we get 44.
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 9:
When dividing 440 by 388, we get 1 with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 143171.1
If we subtract 388 from 440, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
If we divide 520 by 388, we get 1 and a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 143171.11
The remainder is 132 after subtracting 388 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The quotient of the division is 143171.11, and the remainder is 0.132.
