664893 ÷ 53 
Let's see how many times 53 fits into 664893.

Step 1:
53 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 53

On to step 2:
53 goes into 66 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 53 away from 66, we end up with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 53

Moving on to step 3:
If we divide 134 by 53, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 106 away from 134, we end up with 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 53

On to step 4:
When dividing 288 by 53, we get 5 with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtracting 265 from 288 leaves us with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 53

Let's proceed to step 5:
239 divided by 53 is 4 with a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 1254.0
If we subtract 212 from 239, we get 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 53

Let's proceed to step 6:
When dividing 273 by 53, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 12545.0
Subtract 265 from 273 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
The number 53 fits into 80 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 12545.1
Deduct 53 from 80 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
270 divided by 53 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12545.15
Subtracting 265 from 270 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
53 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 12545.15
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
If we divide 500 by 53, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 12545.1509
Deduct 477 from 500 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
230 divided by 53 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 12545.15094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
When dividing 180 by 53, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 12545.150943
Subtracting 159 from 180 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
If we divide 210 by 53, we get 3 and a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 12545.1509433
If we subtract 159 from 210, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

In conclusion, the division gives 12545.1509433 with a balance of 5.1e-07.
