We're dividing 48006873 by 561 
The aim is to understand the frequency of 561 in 48006873.

On to step 1:
561 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 561

Moving on to step 2:
The number 561 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Grab the next digit (0) from the dividend, add it to 48, then carry on: 480 / 561

Let's proceed to step 3:
The number 561 fits into 480 0 times, leaving a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 480 to get 480.
Grab the next digit (0) from the dividend, add it to 480, then carry on: 4800 / 561

On to step 4:
The number 561 fits into 4800 8 times, leaving a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 312 after subtracting 4488 from 4800.
Include the next digit (6) from the dividend after 312, then repeat: 3126 / 561

Advancing to step 5:
561 goes into 3126 5 times with a remainder of 321.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtracting 2805 from 3126 leaves us with 321.
Include the next digit (8) from the dividend after 321, then repeat: 3218 / 561

On to step 6:
3218 divided by 561 is 5 with a remainder of 413.
Use 5 as the next digit of our solution. 
Result so far: 855.0
If we take 2805 away from 3218, we end up with 413.
Fetch the next digit (7) from the dividend, attach it to 413 and continue: 4137 / 561

On to step 7:
When dividing 4137 by 561, we get 7 with a remainder of 210.
Write down 7 as next digit of the result. 
Result so far: 8557.0
Deduct 3927 from 4137 and we're left with 210.
Append the next digit (3) from the dividend to 210 and continue with: 2103 / 561

Step 8:
When dividing 2103 by 561, we get 3 with a remainder of 420.
Put 3 as the next digit of the answer. 
Result so far: 85573.0
If we subtract 1683 from 2103, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 9:
When dividing 4200 by 561, we get 7 with a remainder of 273.
Put 7 as the next digit of the answer. 
Result so far: 85573.7
Deduct 3927 from 4200 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 10:
If we divide 2730 by 561, we get 4 and a remainder of 486.
Put 4 as the next digit of the answer. 
Result so far: 85573.74
The remainder is 486 after subtracting 2244 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 11:
If we divide 4860 by 561, we get 8 and a remainder of 372.
Record the quotient 8 as the next digit in the result. 
Result so far: 85573.748
The remainder is 372 after subtracting 4488 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 12:
561 goes into 3720 6 times with a remainder of 354.
The number 6 becomes the next digit in our result. 
Result so far: 85573.7486
Subtract 3366 from 3720 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 13:
561 can be fit into 3540 6 times, resulting in a remainder of 174.
Write down 6 as next digit of the result. 
Result so far: 85573.74866
The remainder is 174 after subtracting 3366 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The quotient of the division is 85573.74866, and the remainder is 0.000174.
