Let's divide 62151085 by 638
The aim is to understand the frequency of 638 in 62151085.

Going ahead to step 1:
If we divide 6 by 638, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 638

Going ahead to step 2:
The number 638 fits into 62 0 times, leaving a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 638

Advancing to step 3:
621 divided by 638 is 0 with a remainder of 621.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 621 and we're left with 621.
Grab the next digit (5) from the dividend, add it to 621, then carry on: 6215 / 638

Going ahead to step 4:
If we divide 6215 by 638, we get 9 and a remainder of 473.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 5742 from 6215 leaves us with 473.
Take the next digit (1) from the dividend and append it to 473, then repeat: 4731 / 638

Step 5:
4731 divided by 638 is 7 with a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we take 4466 away from 4731, we end up with 265.
Include the next digit (0) from the dividend after 265, then repeat: 2650 / 638

Let's proceed to step 6:
If we divide 2650 by 638, we get 4 and a remainder of 98.
Use 4 as the next digit of our solution. 
Result so far: 974.0
Subtracting 2552 from 2650 leaves us with 98.
Include the next digit (8) from the dividend after 98, then repeat: 988 / 638

On to step 7:
638 goes into 988 1 times with a remainder of 350.
Record the quotient 1 as the next digit in the result. 
Result so far: 9741.0
Subtract 638 from 988 to get 350.
Take the next digit (5) from the dividend and append it to 350, then repeat: 3505 / 638

Advancing to step 8:
3505 divided by 638 is 5 with a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 97415.0
Subtracting 3190 from 3505 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 9:
If we divide 3150 by 638, we get 4 and a remainder of 598.
The next digit of our result is 4. 
Result so far: 97415.4
Subtracting 2552 from 3150 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 10:
638 can be fit into 5980 9 times, resulting in a remainder of 238.
Write down 9 as next digit of the result. 
Result so far: 97415.49
Subtracting 5742 from 5980 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 11:
2380 divided by 638 is 3 with a remainder of 466.
Write down 3 as next digit of the result. 
Result so far: 97415.493
If we take 1914 away from 2380, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 12:
The number 638 fits into 4660 7 times, leaving a remainder of 194.
The next digit of our result is 7. 
Result so far: 97415.4937
Subtracting 4466 from 4660 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 13:
When dividing 1940 by 638, we get 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 97415.49373
Subtract 1914 from 1940 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
If we divide 260 by 638, we get 0 and a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 97415.49373
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 15:
The number 638 fits into 2600 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 97415.4937304
Subtract 2552 from 2600 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
When dividing 480 by 638, we get 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 97415.4937304
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 97415.4937304, with a leftover of 4.8e-07.
