We're dividing 53940547 by 453 
We want to figure out the number of times 53940547 can be divided by 453.

On to step 1:
When dividing 5 by 453, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 453

Moving on to step 2:
453 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 453

On to step 3:
539 divided by 453 is 1 with a remainder of 86.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 453 from 539 to get 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 453

Advancing to step 4:
The number 453 fits into 864 1 times, leaving a remainder of 411.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 411 after subtracting 453 from 864.
Take the next digit (0) from the dividend and append it to 411, then repeat: 4110 / 453

On to step 5:
453 goes into 4110 9 times with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Deduct 4077 from 4110 and we're left with 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 453

Moving on to step 6:
When dividing 335 by 453, we get 0 with a remainder of 335.
The next digit of our result is 0. 
Result so far: 1190.0
The remainder is 335 after subtracting 0 from 335.
Take the next digit (4) from the dividend and append it to 335, then repeat: 3354 / 453

Going ahead to step 7:
The number 453 fits into 3354 7 times, leaving a remainder of 183.
The number 7 becomes the next digit in our result. 
Result so far: 11907.0
Deduct 3171 from 3354 and we're left with 183.
Take the next digit (7) from the dividend and append it to 183, then repeat: 1837 / 453

Moving on to step 8:
If we divide 1837 by 453, we get 4 and a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 119074.0
Subtracting 1812 from 1837 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
When dividing 250 by 453, we get 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 119074.0
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
2500 divided by 453 is 5 with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 119074.05
Deduct 2265 from 2500 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 11:
The number 453 fits into 2350 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 119074.055
If we take 2265 away from 2350, we end up 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.

After the division, we end up with 119074.055 and a remainder of 0.0085.
