54355021 ÷ 988 
The aim is to understand the frequency of 988 in 54355021.

Going ahead to step 1:
When dividing 5 by 988, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 988

Going ahead to step 2:
The number 988 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 988

Advancing to step 3:
When dividing 543 by 988, we get 0 with a remainder of 543.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 543 to get 543.
Fetch the next digit (5) from the dividend, attach it to 543 and continue: 5435 / 988

Step 4:
988 can be fit into 5435 5 times, resulting in a remainder of 495.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 4940 from 5435 and we're left with 495.
Bring next digit (5) of the dividend behind the 495 and repeat the process: 4955 / 988

Step 5:
If we divide 4955 by 988, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 55.0
Deduct 4940 from 4955 and we're left with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 988

Going ahead to step 6:
If we divide 150 by 988, we get 0 and a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 550.0
Subtracting 0 from 150 leaves us with 150.
Grab the next digit (2) from the dividend, add it to 150, then carry on: 1502 / 988

Let's proceed to step 7:
When dividing 1502 by 988, we get 1 with a remainder of 514.
The number 1 becomes the next digit in our result. 
Result so far: 5501.0
Subtracting 988 from 1502 leaves us with 514.
Bring next digit (1) of the dividend behind the 514 and repeat the process: 5141 / 988

Going ahead to step 8:
If we divide 5141 by 988, we get 5 and a remainder of 201.
The next digit of our result is 5. 
Result so far: 55015.0
Deduct 4940 from 5141 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 9:
If we divide 2010 by 988, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 55015.2
If we subtract 1976 from 2010, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
When dividing 340 by 988, we get 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 55015.2
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
3400 divided by 988 is 3 with a remainder of 436.
Write down 3 as next digit of the result. 
Result so far: 55015.203
Subtracting 2964 from 3400 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 12:
When dividing 4360 by 988, we get 4 with a remainder of 408.
Record the quotient 4 as the next digit in the result. 
Result so far: 55015.2034
Deduct 3952 from 4360 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 13:
The number 988 fits into 4080 4 times, leaving a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 55015.20344
Subtracting 3952 from 4080 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 55015.20344 with a remainder of 0.000128.
