Let's divide 8345240 by 574
The aim is to understand the frequency of 574 in 8345240.

Let's proceed to step 1:
574 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 574

Moving on to step 2:
83 divided by 574 is 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 574

Let's proceed to step 3:
When dividing 834 by 574, we get 1 with a remainder of 260.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 574 from 834, we get 260.
Append the next digit (5) from the dividend to 260 and continue with: 2605 / 574

Going ahead to step 4:
574 goes into 2605 4 times with a remainder of 309.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2296 from 2605 leaves us with 309.
Fetch the next digit (2) from the dividend, attach it to 309 and continue: 3092 / 574

Advancing to step 5:
574 can be fit into 3092 5 times, resulting in a remainder of 222.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
If we take 2870 away from 3092, we end up with 222.
Grab the next digit (4) from the dividend, add it to 222, then carry on: 2224 / 574

Advancing to step 6:
574 goes into 2224 3 times with a remainder of 502.
Write down 3 as next digit of the result. 
Result so far: 1453.0
If we take 1722 away from 2224, we end up with 502.
Include the next digit (0) from the dividend after 502, then repeat: 5020 / 574

Advancing to step 7:
If we divide 5020 by 574, we get 8 and a remainder of 428.
The next digit of our result is 8. 
Result so far: 14538.0
If we subtract 4592 from 5020, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 8:
If we divide 4280 by 574, we get 7 and a remainder of 262.
The number 7 becomes the next digit in our result. 
Result so far: 14538.7
Subtract 4018 from 4280 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 9:
574 goes into 2620 4 times with a remainder of 324.
Write down 4 as next digit of the result. 
Result so far: 14538.74
Subtracting 2296 from 2620 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 10:
When dividing 3240 by 574, we get 5 with a remainder of 370.
Put 5 as the next digit of the answer. 
Result so far: 14538.745
Subtract 2870 from 3240 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 11:
574 goes into 3700 6 times with a remainder of 256.
The next digit of our result is 6. 
Result so far: 14538.7456
The remainder is 256 after subtracting 3444 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 12:
If we divide 2560 by 574, we get 4 and a remainder of 264.
Put 4 as the next digit of the answer. 
Result so far: 14538.74564
Subtracting 2296 from 2560 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 13:
574 goes into 2640 4 times with a remainder of 344.
Put 4 as the next digit of the answer. 
Result so far: 14538.745644
If we take 2296 away from 2640, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final result is 14538.745644 with a remainder of 3.44e-05.
