551649 divided by 63 
The aim is to understand the frequency of 63 in 551649.

Step 1:
63 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 63

Moving on to step 2:
63 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 63

Step 3:
551 divided by 63 is 8 with a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 504 from 551 leaves us with 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 63

Advancing to step 4:
When dividing 476 by 63, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 87.0
The remainder is 35 after subtracting 441 from 476.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 63

Let's proceed to step 5:
When dividing 354 by 63, we get 5 with a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 875.0
Deduct 315 from 354 and we're left with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 63

Going ahead to step 6:
63 goes into 399 6 times with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 8756.0
Deduct 378 from 399 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
63 goes into 210 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 8756.3
If we take 189 away from 210, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
63 can be fit into 210 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 8756.33
If we subtract 189 from 210, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 8756.33 with a remaining 0.021.
