686924 ÷ 63 
The aim is to understand the frequency of 63 in 686924.

Advancing to step 1:
When dividing 6 by 63, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 63

Advancing to step 2:
When dividing 68 by 63, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 63 from 68, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 63

Step 3:
The number 63 fits into 56 0 times, leaving a remainder of 56.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 56, we get 56.
Append the next digit (9) from the dividend to 56 and continue with: 569 / 63

Going ahead to step 4:
If we divide 569 by 63, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 109.0
If we take 567 away from 569, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 63

Let's proceed to step 5:
When dividing 22 by 63, we get 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 1090.0
Subtracting 0 from 22 leaves us with 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 63

Let's proceed to step 6:
63 goes into 224 3 times with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 10903.0
Subtracting 189 from 224 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
If we divide 350 by 63, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 10903.5
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
63 can be fit into 350 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 10903.55
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 10903.55, with a leftover of 0.035.
