Let's divide 85749930 by 575
The aim is to understand the frequency of 575 in 85749930.

Advancing to step 1:
575 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 575

Let's proceed to step 2:
If we divide 85 by 575, we get 0 and a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Include the next digit (7) from the dividend after 85, then repeat: 857 / 575

Step 3:
When dividing 857 by 575, we get 1 with a remainder of 282.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 575 from 857 leaves us with 282.
Fetch the next digit (4) from the dividend, attach it to 282 and continue: 2824 / 575

Moving on to step 4:
If we divide 2824 by 575, we get 4 and a remainder of 524.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2300 from 2824, we get 524.
Include the next digit (9) from the dividend after 524, then repeat: 5249 / 575

Let's proceed to step 5:
575 goes into 5249 9 times with a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
If we take 5175 away from 5249, we end up with 74.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 575

Step 6:
575 goes into 749 1 times with a remainder of 174.
Use 1 as the next digit of our solution. 
Result so far: 1491.0
Subtracting 575 from 749 leaves us with 174.
Fetch the next digit (3) from the dividend, attach it to 174 and continue: 1743 / 575

Moving on to step 7:
1743 divided by 575 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 14913.0
Deduct 1725 from 1743 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 575

Going ahead to step 8:
The number 575 fits into 180 0 times, leaving a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 149130.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 9:
If we divide 1800 by 575, we get 3 and a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 149130.3
Deduct 1725 from 1800 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
The number 575 fits into 750 1 times, leaving a remainder of 175.
Record the quotient 1 as the next digit in the result. 
Result so far: 149130.31
Subtract 575 from 750 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 11:
1750 divided by 575 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 149130.313
If we take 1725 away from 1750, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
575 goes into 250 0 times with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 149130.313
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 13:
575 can be fit into 2500 4 times, resulting in a remainder of 200.
The next digit of our result is 4. 
Result so far: 149130.31304
Subtracting 2300 from 2500 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 14:
575 can be fit into 2000 3 times, resulting in a remainder of 275.
Write down 3 as next digit of the result. 
Result so far: 149130.313043
If we take 1725 away from 2000, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 15:
The number 575 fits into 2750 4 times, leaving a remainder of 450.
The number 4 becomes the next digit in our result. 
Result so far: 149130.3130434
If we take 2300 away from 2750, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 16:
575 goes into 4500 7 times with a remainder of 475.
Write down 7 as next digit of the result. 
Result so far: 149130.31304347
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.

The final outcome is 149130.31304347, with a leftover of 4.75e-07.
