91392177 ÷ 528 
Our goal is to divide 91392177 by 528.

On to step 1:
If we divide 9 by 528, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 528

Going ahead to step 2:
When dividing 91 by 528, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 528

Advancing to step 3:
528 can be fit into 913 1 times, resulting in a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 528 from 913 and we're left with 385.
Include the next digit (9) from the dividend after 385, then repeat: 3859 / 528

Let's proceed to step 4:
528 goes into 3859 7 times with a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 3696 from 3859, we get 163.
Grab the next digit (2) from the dividend, add it to 163, then carry on: 1632 / 528

Moving on to step 5:
When dividing 1632 by 528, we get 3 with a remainder of 48.
The next digit of our result is 3. 
Result so far: 173.0
If we take 1584 away from 1632, we end up with 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 528

Step 6:
When dividing 481 by 528, we get 0 with a remainder of 481.
Write down 0 as next digit of the result. 
Result so far: 1730.0
Subtracting 0 from 481 leaves us with 481.
Bring next digit (7) of the dividend behind the 481 and repeat the process: 4817 / 528

Going ahead to step 7:
528 can be fit into 4817 9 times, resulting in a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 17309.0
If we take 4752 away from 4817, we end up with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 528

Step 8:
If we divide 657 by 528, we get 1 and a remainder of 129.
The next digit of our result is 1. 
Result so far: 173091.0
Subtracting 528 from 657 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 9:
1290 divided by 528 is 2 with a remainder of 234.
Put 2 as the next digit of the answer. 
Result so far: 173091.2
If we take 1056 away from 1290, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 10:
2340 divided by 528 is 4 with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 173091.24
If we subtract 2112 from 2340, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 11:
When dividing 2280 by 528, we get 4 with a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 173091.244
Subtract 2112 from 2280 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 173091.244 and a remainder of 0.0168.
