We're dividing 80836667 by 573 
The aim is to understand the frequency of 573 in 80836667.

Advancing to step 1:
573 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 573

Let's proceed to step 2:
When dividing 80 by 573, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 573

Going ahead to step 3:
573 goes into 808 1 times with a remainder of 235.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 573 from 808, we get 235.
Take the next digit (3) from the dividend and append it to 235, then repeat: 2353 / 573

Step 4:
2353 divided by 573 is 4 with a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2292 from 2353 and we're left with 61.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 573

Moving on to step 5:
573 goes into 616 1 times with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtract 573 from 616 to get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 573

Moving on to step 6:
573 can be fit into 436 0 times, resulting in a remainder of 436.
The next digit of our result is 0. 
Result so far: 1410.0
If we subtract 0 from 436, we get 436.
Append the next digit (6) from the dividend to 436 and continue with: 4366 / 573

Step 7:
573 goes into 4366 7 times with a remainder of 355.
The next digit of our result is 7. 
Result so far: 14107.0
Subtract 4011 from 4366 to get 355.
Take the next digit (7) from the dividend and append it to 355, then repeat: 3557 / 573

Advancing to step 8:
The number 573 fits into 3557 6 times, leaving a remainder of 119.
Record the quotient 6 as the next digit in the result. 
Result so far: 141076.0
If we subtract 3438 from 3557, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 9:
The number 573 fits into 1190 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 141076.2
If we take 1146 away from 1190, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
If we divide 440 by 573, we get 0 and a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 141076.2
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
573 can be fit into 4400 7 times, resulting in a remainder of 389.
Put 7 as the next digit of the answer. 
Result so far: 141076.207
If we subtract 4011 from 4400, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 12:
If we divide 3890 by 573, we get 6 and a remainder of 452.
Write down 6 as next digit of the result. 
Result so far: 141076.2076
Subtract 3438 from 3890 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 13:
4520 divided by 573 is 7 with a remainder of 509.
The number 7 becomes the next digit in our result. 
Result so far: 141076.20767
If we take 4011 away from 4520, we end up with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Moving on to step 14:
When dividing 5090 by 573, we get 8 with a remainder of 506.
Record the quotient 8 as the next digit in the result. 
Result so far: 141076.207678
The remainder is 506 after subtracting 4584 from 5090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 15:
5060 divided by 573 is 8 with a remainder of 476.
The next digit of our result is 8. 
Result so far: 141076.2076788
If we subtract 4584 from 5060, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The quotient of the division is 141076.2076788, and the remainder is 4.76e-06.
