623012 divided by 53 
We want to figure out the number of times 623012 can be divided by 53.

Advancing to step 1:
6 divided by 53 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 53

Step 2:
53 can be fit into 62 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 53 from 62 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 53

Step 3:
53 can be fit into 93 1 times, resulting in a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 53 from 93 leaves us with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 53

On to step 4:
The number 53 fits into 400 7 times, leaving a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 117.0
If we subtract 371 from 400, we get 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 53

On to step 5:
291 divided by 53 is 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 1175.0
If we subtract 265 from 291, we get 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 53

On to step 6:
The number 53 fits into 262 4 times, leaving a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 11754.0
If we take 212 away from 262, we end up 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.

Let's proceed to step 7:
The number 53 fits into 500 9 times, leaving a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 11754.9
Subtract 477 from 500 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 8:
The number 53 fits into 230 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 11754.94
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.

Step 9:
If we divide 180 by 53, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 11754.943
Subtract 159 from 180 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
53 goes into 210 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 11754.9433
Subtracting 159 from 210 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 11754.9433, with a leftover of 0.00051.
