We look at the division of 4685276 by 638 
The aim is to understand the frequency of 638 in 4685276.

Advancing to step 1:
The number 638 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 638

Step 2:
638 can be fit into 46 0 times, resulting in a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 638

On to step 3:
When dividing 468 by 638, we get 0 with a remainder of 468.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 468 after subtracting 0 from 468.
Take the next digit (5) from the dividend and append it to 468, then repeat: 4685 / 638

On to step 4:
The number 638 fits into 4685 7 times, leaving a remainder of 219.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 4466 from 4685 leaves us with 219.
Append the next digit (2) from the dividend to 219 and continue with: 2192 / 638

Moving on to step 5:
638 can be fit into 2192 3 times, resulting in a remainder of 278.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
The remainder is 278 after subtracting 1914 from 2192.
Take the next digit (7) from the dividend and append it to 278, then repeat: 2787 / 638

Step 6:
638 goes into 2787 4 times with a remainder of 235.
Use 4 as the next digit of our solution. 
Result so far: 734.0
Subtracting 2552 from 2787 leaves us with 235.
Include the next digit (6) from the dividend after 235, then repeat: 2356 / 638

Step 7:
2356 divided by 638 is 3 with a remainder of 442.
The number 3 becomes the next digit in our result. 
Result so far: 7343.0
Deduct 1914 from 2356 and we're left with 442.
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 8:
When dividing 4420 by 638, we get 6 with a remainder of 592.
Write down 6 as next digit of the result. 
Result so far: 7343.6
The remainder is 592 after subtracting 3828 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 9:
638 goes into 5920 9 times with a remainder of 178.
Write down 9 as next digit of the result. 
Result so far: 7343.69
Subtract 5742 from 5920 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 10:
1780 divided by 638 is 2 with a remainder of 504.
Put 2 as the next digit of the answer. 
Result so far: 7343.692
Deduct 1276 from 1780 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 11:
If we divide 5040 by 638, we get 7 and a remainder of 574.
Write down 7 as next digit of the result. 
Result so far: 7343.6927
Subtract 4466 from 5040 to get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Moving on to step 12:
5740 divided by 638 is 8 with a remainder of 636.
Write down 8 as next digit of the result. 
Result so far: 7343.69278
If we subtract 5104 from 5740, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

On to step 13:
If we divide 6360 by 638, we get 9 and a remainder of 618.
Put 9 as the next digit of the answer. 
Result so far: 7343.692789
Subtracting 5742 from 6360 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 14:
The number 638 fits into 6180 9 times, leaving a remainder of 438.
The number 9 becomes the next digit in our result. 
Result so far: 7343.6927899
Subtracting 5742 from 6180 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The final result is 7343.6927899 with a remainder of 4.38e-06.
