Let's divide 28714174 by 638
The aim is to understand the frequency of 638 in 28714174.

Going ahead to step 1:
The number 638 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 638

Going ahead to step 2:
When dividing 28 by 638, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 638

Going ahead to step 3:
638 can be fit into 287 0 times, resulting in a remainder of 287.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 287 to get 287.
Take the next digit (1) from the dividend and append it to 287, then repeat: 2871 / 638

Going ahead to step 4:
638 goes into 2871 4 times with a remainder of 319.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 2552 from 2871 and we're left with 319.
Fetch the next digit (4) from the dividend, attach it to 319 and continue: 3194 / 638

Let's proceed to step 5:
If we divide 3194 by 638, we get 5 and a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 3190 from 3194 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 638

Step 6:
41 divided by 638 is 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 450.0
Deduct 0 from 41 and we're left with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 638

On to step 7:
417 divided by 638 is 0 with a remainder of 417.
Put 0 as the next digit of the answer. 
Result so far: 4500.0
The remainder is 417 after subtracting 0 from 417.
Include the next digit (4) from the dividend after 417, then repeat: 4174 / 638

Advancing to step 8:
638 can be fit into 4174 6 times, resulting in a remainder of 346.
Write down 6 as next digit of the result. 
Result so far: 45006.0
The remainder is 346 after subtracting 3828 from 4174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 9:
When dividing 3460 by 638, we get 5 with a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 45006.5
Subtracting 3190 from 3460 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
638 can be fit into 2700 4 times, resulting in a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 45006.54
The remainder is 148 after subtracting 2552 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 11:
When dividing 1480 by 638, we get 2 with a remainder of 204.
Record the quotient 2 as the next digit in the result. 
Result so far: 45006.542
Deduct 1276 from 1480 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 12:
638 goes into 2040 3 times with a remainder of 126.
The next digit of our result is 3. 
Result so far: 45006.5423
Subtracting 1914 from 2040 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 13:
638 goes into 1260 1 times with a remainder of 622.
Use 1 as the next digit of our solution. 
Result so far: 45006.54231
Subtract 638 from 1260 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

On to step 14:
When dividing 6220 by 638, we get 9 with a remainder of 478.
Put 9 as the next digit of the answer. 
Result so far: 45006.542319
Deduct 5742 from 6220 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 15:
638 can be fit into 4780 7 times, resulting in a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 45006.5423197
The remainder is 314 after subtracting 4466 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 16:
The number 638 fits into 3140 4 times, leaving a remainder of 588.
Put 4 as the next digit of the answer. 
Result so far: 45006.54231974
If we take 2552 away from 3140, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

After the division, we end up with 45006.54231974 and a remainder of 5.88e-07.
