98018083 divided by 638 
The aim is to understand the frequency of 638 in 98018083.

Advancing to step 1:
638 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 638

Moving on to step 2:
If we divide 98 by 638, we get 0 and a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Append the next digit (0) from the dividend to 98 and continue with: 980 / 638

On to step 3:
If we divide 980 by 638, we get 1 and a remainder of 342.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 342 after subtracting 638 from 980.
Grab the next digit (1) from the dividend, add it to 342, then carry on: 3421 / 638

Let's proceed to step 4:
When dividing 3421 by 638, we get 5 with a remainder of 231.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 3190 from 3421 to get 231.
Include the next digit (8) from the dividend after 231, then repeat: 2318 / 638

Step 5:
When dividing 2318 by 638, we get 3 with a remainder of 404.
Write down 3 as next digit of the result. 
Result so far: 153.0
Subtracting 1914 from 2318 leaves us with 404.
Append the next digit (0) from the dividend to 404 and continue with: 4040 / 638

Let's proceed to step 6:
When dividing 4040 by 638, we get 6 with a remainder of 212.
Put 6 as the next digit of the answer. 
Result so far: 1536.0
If we subtract 3828 from 4040, we get 212.
Grab the next digit (8) from the dividend, add it to 212, then carry on: 2128 / 638

Let's proceed to step 7:
638 can be fit into 2128 3 times, resulting in a remainder of 214.
Write down 3 as next digit of the result. 
Result so far: 15363.0
Subtracting 1914 from 2128 leaves us with 214.
Append the next digit (3) from the dividend to 214 and continue with: 2143 / 638

On to step 8:
When dividing 2143 by 638, we get 3 with a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 153633.0
Subtract 1914 from 2143 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 9:
The number 638 fits into 2290 3 times, leaving a remainder of 376.
Write down 3 as next digit of the result. 
Result so far: 153633.3
If we subtract 1914 from 2290, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 10:
3760 divided by 638 is 5 with a remainder of 570.
The next digit of our result is 5. 
Result so far: 153633.35
Subtracting 3190 from 3760 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 11:
When dividing 5700 by 638, we get 8 with a remainder of 596.
The next digit of our result is 8. 
Result so far: 153633.358
The remainder is 596 after subtracting 5104 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Going ahead to step 12:
638 can be fit into 5960 9 times, resulting in a remainder of 218.
Put 9 as the next digit of the answer. 
Result so far: 153633.3589
Deduct 5742 from 5960 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 13:
638 can be fit into 2180 3 times, resulting in a remainder of 266.
Put 3 as the next digit of the answer. 
Result so far: 153633.35893
If we take 1914 away from 2180, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 14:
638 goes into 2660 4 times with a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 153633.358934
Deduct 2552 from 2660 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 15:
The number 638 fits into 1080 1 times, leaving a remainder of 442.
Record the quotient 1 as the next digit in the result. 
Result so far: 153633.3589341
The remainder is 442 after subtracting 638 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 16:
638 goes into 4420 6 times with a remainder of 592.
Record the quotient 6 as the next digit in the result. 
Result so far: 153633.35893416
If we subtract 3828 from 4420, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The quotient of the division is 153633.35893416, and the remainder is 5.92e-07.
