43931923 ÷ 525 
We want to figure out the number of times 43931923 can be divided by 525.

Advancing to step 1:
If we divide 4 by 525, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 525

Advancing to step 2:
When dividing 43 by 525, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 525

Let's proceed to step 3:
When dividing 439 by 525, we get 0 with a remainder of 439.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 439, we get 439.
Append the next digit (3) from the dividend to 439 and continue with: 4393 / 525

Going ahead to step 4:
If we divide 4393 by 525, we get 8 and a remainder of 193.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 4200 from 4393 leaves us with 193.
Bring next digit (1) of the dividend behind the 193 and repeat the process: 1931 / 525

On to step 5:
525 goes into 1931 3 times with a remainder of 356.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtracting 1575 from 1931 leaves us with 356.
Include the next digit (9) from the dividend after 356, then repeat: 3569 / 525

On to step 6:
If we divide 3569 by 525, we get 6 and a remainder of 419.
Write down 6 as next digit of the result. 
Result so far: 836.0
Subtract 3150 from 3569 to get 419.
Grab the next digit (2) from the dividend, add it to 419, then carry on: 4192 / 525

Let's proceed to step 7:
525 goes into 4192 7 times with a remainder of 517.
The number 7 becomes the next digit in our result. 
Result so far: 8367.0
If we take 3675 away from 4192, we end up with 517.
Fetch the next digit (3) from the dividend, attach it to 517 and continue: 5173 / 525

Step 8:
525 can be fit into 5173 9 times, resulting in a remainder of 448.
Write down 9 as next digit of the result. 
Result so far: 83679.0
If we take 4725 away from 5173, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 9:
525 can be fit into 4480 8 times, resulting in a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 83679.8
Subtract 4200 from 4480 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
2800 divided by 525 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 83679.85
The remainder is 175 after subtracting 2625 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 11:
The number 525 fits into 1750 3 times, leaving a remainder of 175.
Write down 3 as next digit of the result. 
Result so far: 83679.853
The remainder is 175 after subtracting 1575 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 12:
525 can be fit into 1750 3 times, resulting in a remainder of 175.
Write down 3 as next digit of the result. 
Result so far: 83679.8533
Subtracting 1575 from 1750 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final outcome is 83679.8533, with a leftover of 0.00175.
