We look at the division of 43744045 by 573 
The aim is to understand the frequency of 573 in 43744045.

Moving on to step 1:
The number 573 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 573

Going ahead to step 2:
573 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 573

Going ahead to step 3:
573 goes into 437 0 times with a remainder of 437.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 437, we get 437.
Bring next digit (4) of the dividend behind the 437 and repeat the process: 4374 / 573

Advancing to step 4:
573 goes into 4374 7 times with a remainder of 363.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4011 from 4374 leaves us with 363.
Take the next digit (4) from the dividend and append it to 363, then repeat: 3634 / 573

Step 5:
When dividing 3634 by 573, we get 6 with a remainder of 196.
The next digit of our result is 6. 
Result so far: 76.0
The remainder is 196 after subtracting 3438 from 3634.
Grab the next digit (0) from the dividend, add it to 196, then carry on: 1960 / 573

Moving on to step 6:
573 goes into 1960 3 times with a remainder of 241.
Record the quotient 3 as the next digit in the result. 
Result so far: 763.0
If we take 1719 away from 1960, we end up with 241.
Append the next digit (4) from the dividend to 241 and continue with: 2414 / 573

On to step 7:
573 goes into 2414 4 times with a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 7634.0
Subtract 2292 from 2414 to get 122.
Append the next digit (5) from the dividend to 122 and continue with: 1225 / 573

Step 8:
When dividing 1225 by 573, we get 2 with a remainder of 79.
The number 2 becomes the next digit in our result. 
Result so far: 76342.0
Deduct 1146 from 1225 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 9:
790 divided by 573 is 1 with a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 76342.1
Deduct 573 from 790 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 10:
The number 573 fits into 2170 3 times, leaving a remainder of 451.
Write down 3 as next digit of the result. 
Result so far: 76342.13
Subtract 1719 from 2170 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Advancing to step 11:
4510 divided by 573 is 7 with a remainder of 499.
Use 7 as the next digit of our solution. 
Result so far: 76342.137
Subtract 4011 from 4510 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 12:
If we divide 4990 by 573, we get 8 and a remainder of 406.
Write down 8 as next digit of the result. 
Result so far: 76342.1378
The remainder is 406 after subtracting 4584 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 13:
When dividing 4060 by 573, we get 7 with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 76342.13787
If we subtract 4011 from 4060, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
573 goes into 490 0 times with a remainder of 490.
Record the quotient 0 as the next digit in the result. 
Result so far: 76342.13787
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 15:
573 can be fit into 4900 8 times, resulting in a remainder of 316.
The next digit of our result is 8. 
Result so far: 76342.1378708
Deduct 4584 from 4900 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 16:
3160 divided by 573 is 5 with a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 76342.13787085
If we take 2865 away from 3160, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The quotient of the division is 76342.13787085, and the remainder is 2.95e-07.
