We're dividing 43990931 by 528 
We want to figure out the number of times 43990931 can be divided by 528.

Moving on to step 1:
When dividing 4 by 528, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 528

Let's proceed to step 2:
When dividing 43 by 528, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 528

Going ahead to step 3:
528 goes into 439 0 times with a remainder of 439.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 439 and we're left with 439.
Include the next digit (9) from the dividend after 439, then repeat: 4399 / 528

Going ahead to step 4:
The number 528 fits into 4399 8 times, leaving a remainder of 175.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 4224 from 4399, we get 175.
Fetch the next digit (0) from the dividend, attach it to 175 and continue: 1750 / 528

Advancing to step 5:
1750 divided by 528 is 3 with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we take 1584 away from 1750, we end up with 166.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 528

On to step 6:
The number 528 fits into 1669 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 833.0
The remainder is 85 after subtracting 1584 from 1669.
Bring next digit (3) of the dividend behind the 85 and repeat the process: 853 / 528

On to step 7:
853 divided by 528 is 1 with a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 8331.0
The remainder is 325 after subtracting 528 from 853.
Append the next digit (1) from the dividend to 325 and continue with: 3251 / 528

On to step 8:
3251 divided by 528 is 6 with a remainder of 83.
Record the quotient 6 as the next digit in the result. 
Result so far: 83316.0
Subtracting 3168 from 3251 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 9:
When dividing 830 by 528, we get 1 with a remainder of 302.
Put 1 as the next digit of the answer. 
Result so far: 83316.1
If we subtract 528 from 830, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 10:
528 can be fit into 3020 5 times, resulting in a remainder of 380.
Put 5 as the next digit of the answer. 
Result so far: 83316.15
If we take 2640 away from 3020, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 11:
528 goes into 3800 7 times with a remainder of 104.
The next digit of our result is 7. 
Result so far: 83316.157
If we subtract 3696 from 3800, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
If we divide 1040 by 528, we get 1 and a remainder of 512.
The number 1 becomes the next digit in our result. 
Result so far: 83316.1571
Subtracting 528 from 1040 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 13:
5120 divided by 528 is 9 with a remainder of 368.
The number 9 becomes the next digit in our result. 
Result so far: 83316.15719
Deduct 4752 from 5120 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 14:
The number 528 fits into 3680 6 times, leaving a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 83316.157196
Subtracting 3168 from 3680 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 15:
528 goes into 5120 9 times with a remainder of 368.
Record the quotient 9 as the next digit in the result. 
Result so far: 83316.1571969
If we take 4752 away from 5120, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 16:
528 goes into 3680 6 times with a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 83316.15719696
The remainder is 512 after subtracting 3168 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final outcome is 83316.15719696, with a leftover of 5.12e-07.
