We look at the division of 990975 by 53 
We want to figure out the number of times 990975 can be divided by 53.

Step 1:
If we divide 9 by 53, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 53

Let's proceed to step 2:
99 divided by 53 is 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 53 from 99 and we're left with 46.
Grab the next digit (0) from the dividend, add it to 46, then carry on: 460 / 53

Advancing to step 3:
The number 53 fits into 460 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 424 from 460, we get 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 53

Step 4:
If we divide 369 by 53, we get 6 and a remainder of 51.
The next digit of our result is 6. 
Result so far: 186.0
Subtract 318 from 369 to get 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 53

Step 5:
517 divided by 53 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 1869.0
Subtracting 477 from 517 leaves us with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 53

Moving on to step 6:
53 can be fit into 405 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 18697.0
If we subtract 371 from 405, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
If we divide 340 by 53, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 18697.6
Subtracting 318 from 340 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
When dividing 220 by 53, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 18697.64
If we subtract 212 from 220, we 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 9:
If we divide 80 by 53, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 18697.641
Subtract 53 from 80 to get 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 10:
When dividing 270 by 53, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 18697.6415
The remainder is 5 after subtracting 265 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
The number 53 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 18697.6415
Deduct 0 from 50 and we're left 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.

Going ahead to step 12:
500 divided by 53 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 18697.641509
If we take 477 away from 500, we end up 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.

Step 13:
When dividing 230 by 53, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 18697.6415094
The remainder is 18 after subtracting 212 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
The number 53 fits into 180 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 18697.64150943
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.

The final outcome is 18697.64150943, with a leftover of 2.1e-08.
