We're dividing 98015429 by 553 
The aim is to understand the frequency of 553 in 98015429.

Advancing to step 1:
553 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 553

Step 2:
553 goes into 98 0 times with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Include the next digit (0) from the dividend after 98, then repeat: 980 / 553

Step 3:
If we divide 980 by 553, we get 1 and a remainder of 427.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 427 after subtracting 553 from 980.
Take the next digit (1) from the dividend and append it to 427, then repeat: 4271 / 553

On to step 4:
553 goes into 4271 7 times with a remainder of 400.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 3871 from 4271 to get 400.
Bring next digit (5) of the dividend behind the 400 and repeat the process: 4005 / 553

Moving on to step 5:
When dividing 4005 by 553, we get 7 with a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 177.0
Subtracting 3871 from 4005 leaves us with 134.
Take the next digit (4) from the dividend and append it to 134, then repeat: 1344 / 553

Going ahead to step 6:
553 can be fit into 1344 2 times, resulting in a remainder of 238.
The next digit of our result is 2. 
Result so far: 1772.0
If we take 1106 away from 1344, we end up with 238.
Take the next digit (2) from the dividend and append it to 238, then repeat: 2382 / 553

Let's proceed to step 7:
The number 553 fits into 2382 4 times, leaving a remainder of 170.
Put 4 as the next digit of the answer. 
Result so far: 17724.0
The remainder is 170 after subtracting 2212 from 2382.
Fetch the next digit (9) from the dividend, attach it to 170 and continue: 1709 / 553

Advancing to step 8:
If we divide 1709 by 553, we get 3 and a remainder of 50.
The next digit of our result is 3. 
Result so far: 177243.0
If we take 1659 away from 1709, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 553, we get 0 and a remainder of 500.
The next digit of our result is 0. 
Result so far: 177243.0
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 10:
When dividing 5000 by 553, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 177243.09
Deduct 4977 from 5000 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 11:
553 can be fit into 230 0 times, resulting in a remainder of 230.
The next digit of our result is 0. 
Result so far: 177243.09
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 12:
2300 divided by 553 is 4 with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 177243.0904
If we subtract 2212 from 2300, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 13:
If we divide 880 by 553, we get 1 and a remainder of 327.
Record the quotient 1 as the next digit in the result. 
Result so far: 177243.09041
The remainder is 327 after subtracting 553 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 14:
3270 divided by 553 is 5 with a remainder of 505.
Write down 5 as next digit of the result. 
Result so far: 177243.090415
Subtracting 2765 from 3270 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 15:
When dividing 5050 by 553, we get 9 with a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 177243.0904159
If we take 4977 away from 5050, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 16:
553 can be fit into 730 1 times, resulting in a remainder of 177.
Use 1 as the next digit of our solution. 
Result so far: 177243.09041591
If we subtract 553 from 730, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

The final result is 177243.09041591 with a remainder of 1.77e-07.
