We look at the division of 7173273 by 53 
We want to figure out the number of times 7173273 can be divided by 53.

On to step 1:
7 divided by 53 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 53

Moving on to step 2:
53 can be fit into 71 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 18 after subtracting 53 from 71.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 53

Going ahead to step 3:
53 can be fit into 187 3 times, resulting in a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 28 after subtracting 159 from 187.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 53

Moving on to step 4:
53 can be fit into 283 5 times, resulting in a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 135.0
Subtracting 265 from 283 leaves us with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 53

Let's proceed to step 5:
53 can be fit into 182 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 1353.0
Subtract 159 from 182 to get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 53

Going ahead to step 6:
When dividing 237 by 53, we get 4 with a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 13534.0
If we take 212 away from 237, we end up with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 53

Advancing to step 7:
The number 53 fits into 253 4 times, leaving a remainder of 41.
The next digit of our result is 4. 
Result so far: 135344.0
Subtracting 212 from 253 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
When dividing 410 by 53, we get 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 135344.7
Subtracting 371 from 410 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
The number 53 fits into 390 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 135344.77
If we subtract 371 from 390, 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.

The final outcome is 135344.77, with a leftover of 0.019.
