We look at the division of 45456721 by 528 
Let's see how many times 528 fits into 45456721.

Let's proceed to step 1:
528 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 528

Let's proceed to step 2:
528 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 528

Moving on to step 3:
528 goes into 454 0 times with a remainder of 454.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 454 to get 454.
Grab the next digit (5) from the dividend, add it to 454, then carry on: 4545 / 528

On to step 4:
The number 528 fits into 4545 8 times, leaving a remainder of 321.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 4224 from 4545 leaves us with 321.
Grab the next digit (6) from the dividend, add it to 321, then carry on: 3216 / 528

Step 5:
3216 divided by 528 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we take 3168 away from 3216, we end up with 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 528

Let's proceed to step 6:
487 divided by 528 is 0 with a remainder of 487.
Write down 0 as next digit of the result. 
Result so far: 860.0
Subtracting 0 from 487 leaves us with 487.
Grab the next digit (2) from the dividend, add it to 487, then carry on: 4872 / 528

Let's proceed to step 7:
528 goes into 4872 9 times with a remainder of 120.
The next digit of our result is 9. 
Result so far: 8609.0
Subtracting 4752 from 4872 leaves us with 120.
Append the next digit (1) from the dividend to 120 and continue with: 1201 / 528

Let's proceed to step 8:
The number 528 fits into 1201 2 times, leaving a remainder of 145.
Write down 2 as next digit of the result. 
Result so far: 86092.0
If we take 1056 away from 1201, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 9:
If we divide 1450 by 528, we get 2 and a remainder of 394.
Write down 2 as next digit of the result. 
Result so far: 86092.2
The remainder is 394 after subtracting 1056 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 10:
528 can be fit into 3940 7 times, resulting in a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 86092.27
If we subtract 3696 from 3940, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 11:
When dividing 2440 by 528, we get 4 with a remainder of 328.
Use 4 as the next digit of our solution. 
Result so far: 86092.274
Deduct 2112 from 2440 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 12:
528 can be fit into 3280 6 times, resulting in a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 86092.2746
Subtracting 3168 from 3280 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 13:
When dividing 1120 by 528, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 86092.27462
The remainder is 64 after subtracting 1056 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
When dividing 640 by 528, we get 1 with a remainder of 112.
The next digit of our result is 1. 
Result so far: 86092.274621
The remainder is 112 after subtracting 528 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 15:
When dividing 1120 by 528, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 86092.2746212
Subtracting 1056 from 1120 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 16:
528 goes into 640 1 times with a remainder of 112.
Write down 1 as next digit of the result. 
Result so far: 86092.27462121
If we subtract 528 from 640, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 86092.27462121 and a remainder of 1.12e-07.
