438037 ÷ 63 
The aim is to understand the frequency of 63 in 438037.

Let's proceed to step 1:
The number 63 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 63

Step 2:
When dividing 43 by 63, we get 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 63

Going ahead to step 3:
When dividing 438 by 63, we get 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 378 from 438 and we're left with 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 63

On to step 4:
If we divide 600 by 63, we get 9 and a remainder of 33.
The next digit of our result is 9. 
Result so far: 69.0
The remainder is 33 after subtracting 567 from 600.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 63

Step 5:
The number 63 fits into 333 5 times, leaving a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 695.0
If we take 315 away from 333, we end up with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 63

On to step 6:
When dividing 187 by 63, we get 2 with a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 6952.0
If we take 126 away from 187, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
The number 63 fits into 610 9 times, leaving a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 6952.9
If we take 567 away from 610, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 8:
63 can be fit into 430 6 times, resulting in a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 6952.96
Subtracting 378 from 430 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
520 divided by 63 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 6952.968
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 63, we get 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 6952.9682
Subtracting 126 from 160 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.

Let's proceed to step 11:
63 goes into 340 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6952.96825
The remainder is 25 after subtracting 315 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
The number 63 fits into 250 3 times, leaving a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 6952.968253
Subtracting 189 from 250 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 13:
63 can be fit into 610 9 times, resulting in a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 6952.9682539
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 14:
If we divide 430 by 63, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 6952.96825396
Deduct 378 from 430 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 6952.96825396, and the remainder is 5.2e-08.
