We divide 172004 by 53
We want to figure out the number of times 172004 can be divided by 53.

Moving on to step 1:
If we divide 1 by 53, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 53

Moving on to step 2:
If we divide 17 by 53, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 53

Moving on to step 3:
53 goes into 172 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 159 from 172 leaves us with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 53

On to step 4:
130 divided by 53 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 106 from 130 leaves us with 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 53

On to step 5:
The number 53 fits into 240 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 324.0
If we subtract 212 from 240, we get 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 53

Step 6:
284 divided by 53 is 5 with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 3245.0
If we subtract 265 from 284, we get 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 7:
When dividing 190 by 53, we get 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 3245.3
Deduct 159 from 190 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
53 goes into 310 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 3245.35
The remainder is 45 after subtracting 265 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
The number 53 fits into 450 8 times, leaving a remainder of 26.
The next digit of our result is 8. 
Result so far: 3245.358
If we take 424 away from 450, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
The number 53 fits into 260 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 3245.3584
If we subtract 212 from 260, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
When dividing 480 by 53, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 3245.35849
The remainder is 3 after subtracting 477 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
53 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 3245.35849
If we subtract 0 from 30, 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 13:
300 divided by 53 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3245.3584905
Deduct 265 from 300 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
53 can be fit into 350 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 3245.35849056
The remainder is 32 after subtracting 318 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 3245.35849056 with a remainder of 3.2e-08.
