We look at the division of 46872261 by 573 
The aim is to understand the frequency of 573 in 46872261.

On to step 1:
When dividing 4 by 573, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 573

Advancing to step 2:
The number 573 fits into 46 0 times, leaving a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 573

Advancing to step 3:
468 divided by 573 is 0 with a remainder of 468.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 468 and we're left with 468.
Append the next digit (7) from the dividend to 468 and continue with: 4687 / 573

Step 4:
When dividing 4687 by 573, we get 8 with a remainder of 103.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 4584 from 4687 leaves us with 103.
Bring next digit (2) of the dividend behind the 103 and repeat the process: 1032 / 573

Moving on to step 5:
If we divide 1032 by 573, we get 1 and a remainder of 459.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Deduct 573 from 1032 and we're left with 459.
Take the next digit (2) from the dividend and append it to 459, then repeat: 4592 / 573

Going ahead to step 6:
4592 divided by 573 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 818.0
Subtract 4584 from 4592 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 573

Step 7:
The number 573 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 8180.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 573

On to step 8:
The number 573 fits into 861 1 times, leaving a remainder of 288.
The next digit of our result is 1. 
Result so far: 81801.0
Subtract 573 from 861 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 9:
573 can be fit into 2880 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 81801.5
Subtracting 2865 from 2880 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
573 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 81801.5
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
If we divide 1500 by 573, we get 2 and a remainder of 354.
Put 2 as the next digit of the answer. 
Result so far: 81801.502
If we take 1146 away from 1500, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 12:
573 can be fit into 3540 6 times, resulting in a remainder of 102.
Write down 6 as next digit of the result. 
Result so far: 81801.5026
Subtract 3438 from 3540 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 13:
573 goes into 1020 1 times with a remainder of 447.
Use 1 as the next digit of our solution. 
Result so far: 81801.50261
If we take 573 away from 1020, we end up 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.

On to step 14:
If we divide 4470 by 573, we get 7 and a remainder of 459.
Put 7 as the next digit of the answer. 
Result so far: 81801.502617
If we take 4011 away from 4470, we end up with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 15:
573 can be fit into 4590 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 81801.5026178
If we take 4584 away from 4590, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 16:
573 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 81801.5026178
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 81801.5026178 with a balance of 6e-08.
