We're dividing 77383939 by 528 
We want to figure out the number of times 77383939 can be divided by 528.

Step 1:
If we divide 7 by 528, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 528

Going ahead to step 2:
When dividing 77 by 528, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 528

Going ahead to step 3:
528 goes into 773 1 times with a remainder of 245.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 528 from 773 to get 245.
Append the next digit (8) from the dividend to 245 and continue with: 2458 / 528

Moving on to step 4:
When dividing 2458 by 528, we get 4 with a remainder of 346.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 2112 away from 2458, we end up with 346.
Grab the next digit (3) from the dividend, add it to 346, then carry on: 3463 / 528

On to step 5:
3463 divided by 528 is 6 with a remainder of 295.
The next digit of our result is 6. 
Result so far: 146.0
Subtracting 3168 from 3463 leaves us with 295.
Include the next digit (9) from the dividend after 295, then repeat: 2959 / 528

Let's proceed to step 6:
528 goes into 2959 5 times with a remainder of 319.
The next digit of our result is 5. 
Result so far: 1465.0
The remainder is 319 after subtracting 2640 from 2959.
Bring next digit (3) of the dividend behind the 319 and repeat the process: 3193 / 528

Advancing to step 7:
3193 divided by 528 is 6 with a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 14656.0
Subtract 3168 from 3193 to get 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 528

Let's proceed to step 8:
When dividing 259 by 528, we get 0 with a remainder of 259.
Put 0 as the next digit of the answer. 
Result so far: 146560.0
Subtract 0 from 259 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 9:
528 can be fit into 2590 4 times, resulting in a remainder of 478.
Write down 4 as next digit of the result. 
Result so far: 146560.4
The remainder is 478 after subtracting 2112 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 10:
When dividing 4780 by 528, we get 9 with a remainder of 28.
The next digit of our result is 9. 
Result so far: 146560.49
Subtract 4752 from 4780 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
280 divided by 528 is 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 146560.49
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 12:
The number 528 fits into 2800 5 times, leaving a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 146560.4905
If we take 2640 away from 2800, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
The number 528 fits into 1600 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 146560.49053
The remainder is 16 after subtracting 1584 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
The number 528 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 146560.49053
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
When dividing 1600 by 528, we get 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 146560.4905303
Subtract 1584 from 1600 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
528 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 146560.4905303
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 146560.4905303 with a balance of 1.6e-07.
