39978105 divided by 528 
Let's see how many times 528 fits into 39978105.

On to step 1:
If we divide 3 by 528, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 528

Advancing to step 2:
If we divide 39 by 528, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 528

On to step 3:
528 goes into 399 0 times with a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 399, we get 399.
Include the next digit (7) from the dividend after 399, then repeat: 3997 / 528

On to step 4:
The number 528 fits into 3997 7 times, leaving a remainder of 301.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 3696 from 3997, we get 301.
Append the next digit (8) from the dividend to 301 and continue with: 3018 / 528

Moving on to step 5:
If we divide 3018 by 528, we get 5 and a remainder of 378.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 2640 from 3018 and we're left with 378.
Take the next digit (1) from the dividend and append it to 378, then repeat: 3781 / 528

Advancing to step 6:
The number 528 fits into 3781 7 times, leaving a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 757.0
Subtracting 3696 from 3781 leaves us with 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 528

Let's proceed to step 7:
528 can be fit into 850 1 times, resulting in a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 7571.0
The remainder is 322 after subtracting 528 from 850.
Include the next digit (5) from the dividend after 322, then repeat: 3225 / 528

Moving on to step 8:
The number 528 fits into 3225 6 times, leaving a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 75716.0
Deduct 3168 from 3225 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
If we divide 570 by 528, we get 1 and a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 75716.1
Subtract 528 from 570 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
The number 528 fits into 420 0 times, leaving a remainder of 420.
The next digit of our result is 0. 
Result so far: 75716.1
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 11:
If we divide 4200 by 528, we get 7 and a remainder of 504.
Record the quotient 7 as the next digit in the result. 
Result so far: 75716.107
If we subtract 3696 from 4200, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 12:
528 goes into 5040 9 times with a remainder of 288.
The number 9 becomes the next digit in our result. 
Result so far: 75716.1079
If we subtract 4752 from 5040, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 13:
If we divide 2880 by 528, we get 5 and a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 75716.10795
Subtract 2640 from 2880 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
528 can be fit into 2400 4 times, resulting in a remainder of 288.
The next digit of our result is 4. 
Result so far: 75716.107954
Deduct 2112 from 2400 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 15:
528 goes into 2880 5 times with a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 75716.1079545
Subtract 2640 from 2880 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
The number 528 fits into 2400 4 times, leaving a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 75716.10795454
Subtracting 2112 from 2400 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final result is 75716.10795454 with a remainder of 2.88e-07.
