We look at the division of 91388569 by 165 
We're looking to find how many times 165 goes into 91388569.

Moving on to step 1:
When dividing 9 by 165, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 165

Going ahead to step 2:
When dividing 91 by 165, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 165

Going ahead to step 3:
913 divided by 165 is 5 with a remainder of 88.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 825 from 913 to get 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 165

Advancing to step 4:
165 goes into 888 5 times with a remainder of 63.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 825 from 888 leaves us with 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 165

Advancing to step 5:
638 divided by 165 is 3 with a remainder of 143.
The next digit of our result is 3. 
Result so far: 553.0
If we subtract 495 from 638, we get 143.
Grab the next digit (5) from the dividend, add it to 143, then carry on: 1435 / 165

Going ahead to step 6:
1435 divided by 165 is 8 with a remainder of 115.
Write down 8 as next digit of the result. 
Result so far: 5538.0
Deduct 1320 from 1435 and we're left with 115.
Bring next digit (6) of the dividend behind the 115 and repeat the process: 1156 / 165

Advancing to step 7:
The number 165 fits into 1156 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 55387.0
The remainder is 1 after subtracting 1155 from 1156.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 165

Step 8:
165 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 553870.0
Deduct 0 from 19 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
The number 165 fits into 190 1 times, leaving a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 553870.1
The remainder is 25 after subtracting 165 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
165 can be fit into 250 1 times, resulting in a remainder of 85.
The next digit of our result is 1. 
Result so far: 553870.11
Deduct 165 from 250 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 553870.11 with a remaining 0.085.
