96800584 ÷ 638 
The aim is to understand the frequency of 638 in 96800584.

Advancing to step 1:
638 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 638

Going ahead to step 2:
When dividing 96 by 638, we get 0 with a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 96 leaves us with 96.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 638

Advancing to step 3:
When dividing 968 by 638, we get 1 with a remainder of 330.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 638 from 968, we get 330.
Grab the next digit (0) from the dividend, add it to 330, then carry on: 3300 / 638

Advancing to step 4:
3300 divided by 638 is 5 with a remainder of 110.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 3190 from 3300 and we're left with 110.
Append the next digit (0) from the dividend to 110 and continue with: 1100 / 638

Going ahead to step 5:
1100 divided by 638 is 1 with a remainder of 462.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
The remainder is 462 after subtracting 638 from 1100.
Append the next digit (5) from the dividend to 462 and continue with: 4625 / 638

Step 6:
638 goes into 4625 7 times with a remainder of 159.
The next digit of our result is 7. 
Result so far: 1517.0
Subtract 4466 from 4625 to get 159.
Grab the next digit (8) from the dividend, add it to 159, then carry on: 1598 / 638

Going ahead to step 7:
If we divide 1598 by 638, we get 2 and a remainder of 322.
Write down 2 as next digit of the result. 
Result so far: 15172.0
If we subtract 1276 from 1598, we get 322.
Fetch the next digit (4) from the dividend, attach it to 322 and continue: 3224 / 638

Moving on to step 8:
When dividing 3224 by 638, we get 5 with a remainder of 34.
The next digit of our result is 5. 
Result so far: 151725.0
Subtracting 3190 from 3224 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
638 can be fit into 340 0 times, resulting in a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 151725.0
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
When dividing 3400 by 638, we get 5 with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 151725.05
If we subtract 3190 from 3400, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 11:
2100 divided by 638 is 3 with a remainder of 186.
The next digit of our result is 3. 
Result so far: 151725.053
The remainder is 186 after subtracting 1914 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 12:
The number 638 fits into 1860 2 times, leaving a remainder of 584.
Put 2 as the next digit of the answer. 
Result so far: 151725.0532
If we take 1276 away from 1860, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 13:
When dividing 5840 by 638, we get 9 with a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 151725.05329
If we subtract 5742 from 5840, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 14:
638 goes into 980 1 times with a remainder of 342.
The number 1 becomes the next digit in our result. 
Result so far: 151725.053291
Deduct 638 from 980 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 15:
When dividing 3420 by 638, we get 5 with a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 151725.0532915
Deduct 3190 from 3420 and we're left with 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 16:
638 can be fit into 2300 3 times, resulting in a remainder of 386.
The number 3 becomes the next digit in our result. 
Result so far: 151725.05329153
Subtracting 1914 from 2300 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

In conclusion, the division gives 151725.05329153 with a balance of 3.86e-07.
