We divide 45663985 by 553
The aim is to understand the frequency of 553 in 45663985.

Moving on to step 1:
4 divided by 553 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 553

Moving on to step 2:
553 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 553

On to step 3:
553 can be fit into 456 0 times, resulting in a remainder of 456.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 456 and we're left with 456.
Grab the next digit (6) from the dividend, add it to 456, then carry on: 4566 / 553

Let's proceed to step 4:
The number 553 fits into 4566 8 times, leaving a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 4424 from 4566 to get 142.
Take the next digit (3) from the dividend and append it to 142, then repeat: 1423 / 553

Advancing to step 5:
1423 divided by 553 is 2 with a remainder of 317.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we take 1106 away from 1423, we end up with 317.
Bring next digit (9) of the dividend behind the 317 and repeat the process: 3179 / 553

Moving on to step 6:
When dividing 3179 by 553, we get 5 with a remainder of 414.
Use 5 as the next digit of our solution. 
Result so far: 825.0
Deduct 2765 from 3179 and we're left with 414.
Bring next digit (8) of the dividend behind the 414 and repeat the process: 4148 / 553

Going ahead to step 7:
If we divide 4148 by 553, we get 7 and a remainder of 277.
The next digit of our result is 7. 
Result so far: 8257.0
If we subtract 3871 from 4148, we get 277.
Grab the next digit (5) from the dividend, add it to 277, then carry on: 2775 / 553

Moving on to step 8:
If we divide 2775 by 553, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 82575.0
Subtracting 2765 from 2775 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 553, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 82575.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
The number 553 fits into 1000 1 times, leaving a remainder of 447.
The number 1 becomes the next digit in our result. 
Result so far: 82575.01
Subtracting 553 from 1000 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 11:
If we divide 4470 by 553, we get 8 and a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 82575.018
If we subtract 4424 from 4470, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
553 can be fit into 460 0 times, resulting in a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 82575.018
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 13:
If we divide 4600 by 553, we get 8 and a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 82575.01808
If we subtract 4424 from 4600, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 14:
553 can be fit into 1760 3 times, resulting in a remainder of 101.
Write down 3 as next digit of the result. 
Result so far: 82575.018083
If we take 1659 away from 1760, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 15:
The number 553 fits into 1010 1 times, leaving a remainder of 457.
Write down 1 as next digit of the result. 
Result so far: 82575.0180831
Subtract 553 from 1010 to get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 16:
553 goes into 4570 8 times with a remainder of 146.
The number 8 becomes the next digit in our result. 
Result so far: 82575.01808318
Subtract 4424 from 4570 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final result is 82575.01808318 with a remainder of 1.46e-07.
