We're dividing 78773594 by 528 
Our goal is to divide 78773594 by 528.

Step 1:
The number 528 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 528

Going ahead to step 2:
The number 528 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 528

Let's proceed to step 3:
If we divide 787 by 528, we get 1 and a remainder of 259.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 528 away from 787, we end up with 259.
Fetch the next digit (7) from the dividend, attach it to 259 and continue: 2597 / 528

Going ahead to step 4:
If we divide 2597 by 528, we get 4 and a remainder of 485.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 2112 from 2597 leaves us with 485.
Take the next digit (3) from the dividend and append it to 485, then repeat: 4853 / 528

Step 5:
When dividing 4853 by 528, we get 9 with a remainder of 101.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
Subtracting 4752 from 4853 leaves us with 101.
Grab the next digit (5) from the dividend, add it to 101, then carry on: 1015 / 528

Step 6:
528 goes into 1015 1 times with a remainder of 487.
The number 1 becomes the next digit in our result. 
Result so far: 1491.0
Deduct 528 from 1015 and we're left with 487.
Take the next digit (9) from the dividend and append it to 487, then repeat: 4879 / 528

Going ahead to step 7:
When dividing 4879 by 528, we get 9 with a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 14919.0
The remainder is 127 after subtracting 4752 from 4879.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 528

Let's proceed to step 8:
When dividing 1274 by 528, we get 2 with a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 149192.0
Subtracting 1056 from 1274 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
528 can be fit into 2180 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 149192.4
Deduct 2112 from 2180 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
When dividing 680 by 528, we get 1 with a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 149192.41
If we subtract 528 from 680, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
If we divide 1520 by 528, we get 2 and a remainder of 464.
Use 2 as the next digit of our solution. 
Result so far: 149192.412
If we take 1056 away from 1520, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 12:
4640 divided by 528 is 8 with a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 149192.4128
Deduct 4224 from 4640 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 13:
If we divide 4160 by 528, we get 7 and a remainder of 464.
Write down 7 as next digit of the result. 
Result so far: 149192.41287
If we subtract 3696 from 4160, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 14:
528 can be fit into 4640 8 times, resulting in a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 149192.412878
Subtract 4224 from 4640 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 15:
The number 528 fits into 4160 7 times, leaving a remainder of 464.
The number 7 becomes the next digit in our result. 
Result so far: 149192.4128787
If we subtract 3696 from 4160, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 16:
528 can be fit into 4640 8 times, resulting in a remainder of 416.
The next digit of our result is 8. 
Result so far: 149192.41287878
Subtracting 4224 from 4640 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

After the division, we end up with 149192.41287878 and a remainder of 4.16e-07.
