We're dividing 71438729 by 575 
The aim is to understand the frequency of 575 in 71438729.

Let's proceed to step 1:
7 divided by 575 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 575

On to step 2:
575 can be fit into 71 0 times, resulting in a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 575

Step 3:
714 divided by 575 is 1 with a remainder of 139.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 139 after subtracting 575 from 714.
Grab the next digit (3) from the dividend, add it to 139, then carry on: 1393 / 575

Advancing to step 4:
The number 575 fits into 1393 2 times, leaving a remainder of 243.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1150 from 1393 and we're left with 243.
Take the next digit (8) from the dividend and append it to 243, then repeat: 2438 / 575

On to step 5:
When dividing 2438 by 575, we get 4 with a remainder of 138.
Write down 4 as next digit of the result. 
Result so far: 124.0
Deduct 2300 from 2438 and we're left with 138.
Grab the next digit (7) from the dividend, add it to 138, then carry on: 1387 / 575

Moving on to step 6:
1387 divided by 575 is 2 with a remainder of 237.
The next digit of our result is 2. 
Result so far: 1242.0
If we subtract 1150 from 1387, we get 237.
Include the next digit (2) from the dividend after 237, then repeat: 2372 / 575

Advancing to step 7:
The number 575 fits into 2372 4 times, leaving a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 12424.0
Subtract 2300 from 2372 to get 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 575

On to step 8:
The number 575 fits into 729 1 times, leaving a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 124241.0
If we take 575 away from 729, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 9:
When dividing 1540 by 575, we get 2 with a remainder of 390.
Use 2 as the next digit of our solution. 
Result so far: 124241.2
The remainder is 390 after subtracting 1150 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
If we divide 3900 by 575, we get 6 and a remainder of 450.
The next digit of our result is 6. 
Result so far: 124241.26
Subtract 3450 from 3900 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 11:
575 can be fit into 4500 7 times, resulting in a remainder of 475.
Write down 7 as next digit of the result. 
Result so far: 124241.267
If we take 4025 away from 4500, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 12:
When dividing 4750 by 575, we get 8 with a remainder of 150.
Use 8 as the next digit of our solution. 
Result so far: 124241.2678
The remainder is 150 after subtracting 4600 from 4750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
The number 575 fits into 1500 2 times, leaving a remainder of 350.
Put 2 as the next digit of the answer. 
Result so far: 124241.26782
The remainder is 350 after subtracting 1150 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 14:
If we divide 3500 by 575, we get 6 and a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 124241.267826
The remainder is 50 after subtracting 3450 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 15:
The number 575 fits into 500 0 times, leaving a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 124241.267826
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 16:
When dividing 5000 by 575, we get 8 with a remainder of 400.
Put 8 as the next digit of the answer. 
Result so far: 124241.26782608
The remainder is 400 after subtracting 4600 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 124241.26782608 with a remaining 4e-07.
