We're dividing 52234865 by 574 
The aim is to understand the frequency of 574 in 52234865.

On to step 1:
When dividing 5 by 574, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 574

Step 2:
574 can be fit into 52 0 times, resulting in a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 574

Advancing to step 3:
574 can be fit into 522 0 times, resulting in a remainder of 522.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 522 and we're left with 522.
Grab the next digit (3) from the dividend, add it to 522, then carry on: 5223 / 574

Going ahead to step 4:
574 can be fit into 5223 9 times, resulting in a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 5166 from 5223 leaves us with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 574

Let's proceed to step 5:
574 divided by 574 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 91.0
If we subtract 574 from 574, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 574

Step 6:
8 divided by 574 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 910.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 574

Advancing to step 7:
The number 574 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 9100.0
If we subtract 0 from 86, we get 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 574

Let's proceed to step 8:
The number 574 fits into 865 1 times, leaving a remainder of 291.
Put 1 as the next digit of the answer. 
Result so far: 91001.0
Subtracting 574 from 865 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 9:
574 can be fit into 2910 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 91001.5
Subtracting 2870 from 2910 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
If we divide 400 by 574, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 91001.5
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 11:
574 can be fit into 4000 6 times, resulting in a remainder of 556.
The number 6 becomes the next digit in our result. 
Result so far: 91001.506
Subtract 3444 from 4000 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 12:
If we divide 5560 by 574, we get 9 and a remainder of 394.
The next digit of our result is 9. 
Result so far: 91001.5069
If we subtract 5166 from 5560, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 13:
3940 divided by 574 is 6 with a remainder of 496.
Record the quotient 6 as the next digit in the result. 
Result so far: 91001.50696
If we take 3444 away from 3940, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 14:
574 can be fit into 4960 8 times, resulting in a remainder of 368.
The next digit of our result is 8. 
Result so far: 91001.506968
Subtract 4592 from 4960 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 15:
The number 574 fits into 3680 6 times, leaving a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 91001.5069686
If we subtract 3444 from 3680, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 16:
2360 divided by 574 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 91001.50696864
Subtracting 2296 from 2360 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 91001.50696864 with a remainder of 6.4e-08.
