We divide 90397270 by 528
We want to figure out the number of times 90397270 can be divided by 528.

Moving on to step 1:
528 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 528

Step 2:
528 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (3) from the dividend after 90, then repeat: 903 / 528

On to step 3:
528 can be fit into 903 1 times, resulting in a remainder of 375.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 375 after subtracting 528 from 903.
Append the next digit (9) from the dividend to 375 and continue with: 3759 / 528

Moving on to step 4:
528 can be fit into 3759 7 times, resulting in a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 3696 from 3759, we get 63.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 528

Step 5:
When dividing 637 by 528, we get 1 with a remainder of 109.
The next digit of our result is 1. 
Result so far: 171.0
Subtracting 528 from 637 leaves us with 109.
Bring next digit (2) of the dividend behind the 109 and repeat the process: 1092 / 528

Moving on to step 6:
If we divide 1092 by 528, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 1712.0
If we subtract 1056 from 1092, we get 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 528

Step 7:
528 goes into 367 0 times with a remainder of 367.
The next digit of our result is 0. 
Result so far: 17120.0
Subtract 0 from 367 to get 367.
Fetch the next digit (0) from the dividend, attach it to 367 and continue: 3670 / 528

On to step 8:
If we divide 3670 by 528, we get 6 and a remainder of 502.
The number 6 becomes the next digit in our result. 
Result so far: 171206.0
Subtracting 3168 from 3670 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 9:
If we divide 5020 by 528, we get 9 and a remainder of 268.
Put 9 as the next digit of the answer. 
Result so far: 171206.9
Subtract 4752 from 5020 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 10:
The number 528 fits into 2680 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 171206.95
The remainder is 40 after subtracting 2640 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 528 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 171206.95
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
When dividing 4000 by 528, we get 7 with a remainder of 304.
Use 7 as the next digit of our solution. 
Result so far: 171206.9507
The remainder is 304 after subtracting 3696 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 13:
528 goes into 3040 5 times with a remainder of 400.
Write down 5 as next digit of the result. 
Result so far: 171206.95075
If we subtract 2640 from 3040, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 14:
When dividing 4000 by 528, we get 7 with a remainder of 304.
Use 7 as the next digit of our solution. 
Result so far: 171206.950757
Deduct 3696 from 4000 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 15:
When dividing 3040 by 528, we get 5 with a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 171206.9507575
If we subtract 2640 from 3040, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 16:
When dividing 4000 by 528, we get 7 with a remainder of 304.
The number 7 becomes the next digit in our result. 
Result so far: 171206.95075757
The remainder is 304 after subtracting 3696 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final outcome is 171206.95075757, with a leftover of 3.04e-07.
