We're dividing 43173833 by 574 
The aim is to understand the frequency of 574 in 43173833.

Going ahead to step 1:
4 divided by 574 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 574

Advancing to step 2:
43 divided by 574 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 574

Going ahead to step 3:
574 goes into 431 0 times with a remainder of 431.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 431 after subtracting 0 from 431.
Include the next digit (7) from the dividend after 431, then repeat: 4317 / 574

Let's proceed to step 4:
574 can be fit into 4317 7 times, resulting in a remainder of 299.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4018 from 4317, we get 299.
Append the next digit (3) from the dividend to 299 and continue with: 2993 / 574

Let's proceed to step 5:
574 can be fit into 2993 5 times, resulting in a remainder of 123.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we take 2870 away from 2993, we end up with 123.
Take the next digit (8) from the dividend and append it to 123, then repeat: 1238 / 574

Moving on to step 6:
When dividing 1238 by 574, we get 2 with a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 752.0
If we subtract 1148 from 1238, we get 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 574

On to step 7:
574 can be fit into 903 1 times, resulting in a remainder of 329.
Record the quotient 1 as the next digit in the result. 
Result so far: 7521.0
If we subtract 574 from 903, we get 329.
Grab the next digit (3) from the dividend, add it to 329, then carry on: 3293 / 574

On to step 8:
If we divide 3293 by 574, we get 5 and a remainder of 423.
Use 5 as the next digit of our solution. 
Result so far: 75215.0
If we take 2870 away from 3293, we end up with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Going ahead to step 9:
4230 divided by 574 is 7 with a remainder of 212.
Record the quotient 7 as the next digit in the result. 
Result so far: 75215.7
If we subtract 4018 from 4230, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 10:
2120 divided by 574 is 3 with a remainder of 398.
Record the quotient 3 as the next digit in the result. 
Result so far: 75215.73
The remainder is 398 after subtracting 1722 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 11:
574 can be fit into 3980 6 times, resulting in a remainder of 536.
Put 6 as the next digit of the answer. 
Result so far: 75215.736
The remainder is 536 after subtracting 3444 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 12:
When dividing 5360 by 574, we get 9 with a remainder of 194.
Use 9 as the next digit of our solution. 
Result so far: 75215.7369
If we take 5166 away from 5360, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 13:
The number 574 fits into 1940 3 times, leaving a remainder of 218.
Write down 3 as next digit of the result. 
Result so far: 75215.73693
If we take 1722 away from 1940, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 14:
If we divide 2180 by 574, we get 3 and a remainder of 458.
Put 3 as the next digit of the answer. 
Result so far: 75215.736933
If we subtract 1722 from 2180, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

The final result is 75215.736933 with a remainder of 4.58e-05.
