We look at the division of 91665216 by 525 
We want to divide 91665216 by 525.

Step 1:
When dividing 9 by 525, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 525

Moving on to step 2:
525 can be fit into 91 0 times, resulting in a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Fetch the next digit (6) from the dividend, attach it to 91 and continue: 916 / 525

Going ahead to step 3:
916 divided by 525 is 1 with a remainder of 391.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 525 from 916 and we're left with 391.
Append the next digit (6) from the dividend to 391 and continue with: 3916 / 525

Step 4:
If we divide 3916 by 525, we get 7 and a remainder of 241.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 3675 from 3916 to get 241.
Take the next digit (5) from the dividend and append it to 241, then repeat: 2415 / 525

On to step 5:
525 can be fit into 2415 4 times, resulting in a remainder of 315.
Write down 4 as next digit of the result. 
Result so far: 174.0
The remainder is 315 after subtracting 2100 from 2415.
Bring next digit (2) of the dividend behind the 315 and repeat the process: 3152 / 525

Step 6:
3152 divided by 525 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 1746.0
The remainder is 2 after subtracting 3150 from 3152.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 525

Going ahead to step 7:
525 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 17460.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 525

Step 8:
The number 525 fits into 216 0 times, leaving a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 174600.0
Subtract 0 from 216 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 9:
525 goes into 2160 4 times with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 174600.4
Subtract 2100 from 2160 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
When dividing 600 by 525, we get 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 174600.41
If we subtract 525 from 600, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
When dividing 750 by 525, we get 1 with a remainder of 225.
The number 1 becomes the next digit in our result. 
Result so far: 174600.411
If we take 525 away from 750, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final outcome is 174600.411, with a leftover of 0.0225.
