435216 ÷ 63 
The aim is to understand the frequency of 63 in 435216.

On to step 1:
If we divide 4 by 63, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 63

Let's proceed to step 2:
The number 63 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 63

Moving on to step 3:
63 goes into 435 6 times with a remainder of 57.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 378 from 435 leaves us with 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 63

Let's proceed to step 4:
63 goes into 572 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
If we take 567 away from 572, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 63

Advancing to step 5:
51 divided by 63 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 690.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 63

On to step 6:
When dividing 516 by 63, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 6908.0
The remainder is 12 after subtracting 504 from 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
63 can be fit into 120 1 times, resulting in a remainder of 57.
The next digit of our result is 1. 
Result so far: 6908.1
The remainder is 57 after subtracting 63 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 8:
63 can be fit into 570 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 6908.19
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
If we divide 30 by 63, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 6908.19
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
63 goes into 300 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 6908.1904
If we take 252 away from 300, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
480 divided by 63 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 6908.19047
Subtract 441 from 480 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
If we divide 390 by 63, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 6908.190476
Subtract 378 from 390 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
63 goes into 120 1 times with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 6908.1904761
The remainder is 57 after subtracting 63 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 14:
If we divide 570 by 63, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 6908.19047619
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 6908.19047619, with a leftover of 3e-09.
