63813561 divided by 552 
The aim is to understand the frequency of 552 in 63813561.

Let's proceed to step 1:
When dividing 6 by 552, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 552

On to step 2:
The number 552 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 552

Going ahead to step 3:
552 goes into 638 1 times with a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 552 from 638, we get 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 552

Let's proceed to step 4:
552 goes into 861 1 times with a remainder of 309.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 552 from 861 to get 309.
Append the next digit (3) from the dividend to 309 and continue with: 3093 / 552

On to step 5:
If we divide 3093 by 552, we get 5 and a remainder of 333.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Subtracting 2760 from 3093 leaves us with 333.
Include the next digit (5) from the dividend after 333, then repeat: 3335 / 552

Moving on to step 6:
The number 552 fits into 3335 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 1156.0
If we take 3312 away from 3335, we end up with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 552

On to step 7:
552 can be fit into 236 0 times, resulting in a remainder of 236.
Record the quotient 0 as the next digit in the result. 
Result so far: 11560.0
Subtract 0 from 236 to get 236.
Take the next digit (1) from the dividend and append it to 236, then repeat: 2361 / 552

Step 8:
When dividing 2361 by 552, we get 4 with a remainder of 153.
Put 4 as the next digit of the answer. 
Result so far: 115604.0
If we take 2208 away from 2361, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 9:
1530 divided by 552 is 2 with a remainder of 426.
The next digit of our result is 2. 
Result so far: 115604.2
Deduct 1104 from 1530 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 10:
If we divide 4260 by 552, we get 7 and a remainder of 396.
The number 7 becomes the next digit in our result. 
Result so far: 115604.27
Deduct 3864 from 4260 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 11:
If we divide 3960 by 552, we get 7 and a remainder of 96.
Write down 7 as next digit of the result. 
Result so far: 115604.277
Subtract 3864 from 3960 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 115604.277 and a remainder of 0.0096.
