We look at the division of 33857424 by 988 
The aim is to understand the frequency of 988 in 33857424.

Going ahead to step 1:
988 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 988

Let's proceed to step 2:
The number 988 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 988

On to step 3:
338 divided by 988 is 0 with a remainder of 338.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 338, we get 338.
Include the next digit (5) from the dividend after 338, then repeat: 3385 / 988

Advancing to step 4:
When dividing 3385 by 988, we get 3 with a remainder of 421.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 421 after subtracting 2964 from 3385.
Grab the next digit (7) from the dividend, add it to 421, then carry on: 4217 / 988

Moving on to step 5:
988 can be fit into 4217 4 times, resulting in a remainder of 265.
The next digit of our result is 4. 
Result so far: 34.0
Subtract 3952 from 4217 to get 265.
Include the next digit (4) from the dividend after 265, then repeat: 2654 / 988

Step 6:
2654 divided by 988 is 2 with a remainder of 678.
Record the quotient 2 as the next digit in the result. 
Result so far: 342.0
Deduct 1976 from 2654 and we're left with 678.
Bring next digit (2) of the dividend behind the 678 and repeat the process: 6782 / 988

Step 7:
988 can be fit into 6782 6 times, resulting in a remainder of 854.
Put 6 as the next digit of the answer. 
Result so far: 3426.0
Subtract 5928 from 6782 to get 854.
Fetch the next digit (4) from the dividend, attach it to 854 and continue: 8544 / 988

Let's proceed to step 8:
988 goes into 8544 8 times with a remainder of 640.
Record the quotient 8 as the next digit in the result. 
Result so far: 34268.0
If we subtract 7904 from 8544, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 9:
988 can be fit into 6400 6 times, resulting in a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 34268.6
The remainder is 472 after subtracting 5928 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 10:
When dividing 4720 by 988, we get 4 with a remainder of 768.
Write down 4 as next digit of the result. 
Result so far: 34268.64
Deduct 3952 from 4720 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Step 11:
988 goes into 7680 7 times with a remainder of 764.
Write down 7 as next digit of the result. 
Result so far: 34268.647
Subtracting 6916 from 7680 leaves us with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

On to step 12:
If we divide 7640 by 988, we get 7 and a remainder of 724.
Use 7 as the next digit of our solution. 
Result so far: 34268.6477
Subtracting 6916 from 7640 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

The final result is 34268.6477 with a remainder of 0.00724.
