75943903 divided by 527 
The aim is to understand the frequency of 527 in 75943903.

Step 1:
527 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 527

Moving on to step 2:
If we divide 75 by 527, we get 0 and a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 527

Moving on to step 3:
527 goes into 759 1 times with a remainder of 232.
The next digit of our result is 1. 
Result so far: 1.0
If we take 527 away from 759, we end up with 232.
Include the next digit (4) from the dividend after 232, then repeat: 2324 / 527

Let's proceed to step 4:
2324 divided by 527 is 4 with a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 216 after subtracting 2108 from 2324.
Append the next digit (3) from the dividend to 216 and continue with: 2163 / 527

Step 5:
When dividing 2163 by 527, we get 4 with a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 144.0
Deduct 2108 from 2163 and we're left with 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 527

Going ahead to step 6:
If we divide 559 by 527, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1441.0
Subtracting 527 from 559 leaves us with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 527

Advancing to step 7:
527 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 14410.0
Deduct 0 from 320 and we're left with 320.
Bring next digit (3) of the dividend behind the 320 and repeat the process: 3203 / 527

Going ahead to step 8:
527 goes into 3203 6 times with a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 144106.0
Subtracting 3162 from 3203 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
The number 527 fits into 410 0 times, leaving a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 144106.0
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 10:
527 can be fit into 4100 7 times, resulting in a remainder of 411.
Put 7 as the next digit of the answer. 
Result so far: 144106.07
The remainder is 411 after subtracting 3689 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Let's proceed to step 11:
527 can be fit into 4110 7 times, resulting in a remainder of 421.
Record the quotient 7 as the next digit in the result. 
Result so far: 144106.077
If we take 3689 away from 4110, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

The final outcome is 144106.077, with a leftover of 0.0421.
