17213397 ÷ 165 
We want to figure out the number of times 17213397 can be divided by 165.

Going ahead to step 1:
165 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 165

Moving on to step 2:
17 divided by 165 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 165

Advancing to step 3:
When dividing 172 by 165, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 165 from 172, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 165

Advancing to step 4:
71 divided by 165 is 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 71, we end up with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 165

On to step 5:
713 divided by 165 is 4 with a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Deduct 660 from 713 and we're left with 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 165

Advancing to step 6:
The number 165 fits into 533 3 times, leaving a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 1043.0
If we take 495 away from 533, we end up with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 165

Step 7:
165 can be fit into 389 2 times, resulting in a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 10432.0
The remainder is 59 after subtracting 330 from 389.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 165

Moving on to step 8:
When dividing 597 by 165, we get 3 with a remainder of 102.
Record the quotient 3 as the next digit in the result. 
Result so far: 104323.0
Subtracting 495 from 597 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 9:
If we divide 1020 by 165, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 104323.6
If we subtract 990 from 1020, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 165 is 1 with a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 104323.61
Subtracting 165 from 300 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 11:
When dividing 1350 by 165, we get 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 104323.618
The remainder is 30 after subtracting 1320 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
165 goes into 300 1 times with a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 104323.6181
If we subtract 165 from 300, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 13:
165 goes into 1350 8 times with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 104323.61818
If we subtract 1320 from 1350, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 165 is 1 with a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 104323.618181
Subtracting 165 from 300 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 15:
The number 165 fits into 1350 8 times, leaving a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 104323.6181818
If we take 1320 away from 1350, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 16:
When dividing 300 by 165, we get 1 with a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 104323.61818181
Subtracting 165 from 300 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final outcome is 104323.61818181, with a leftover of 1.35e-07.
