We look at the division of 989352 by 53 
The aim is to understand the frequency of 53 in 989352.

On to step 1:
If we divide 9 by 53, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 53

Advancing to step 2:
When dividing 98 by 53, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 45 after subtracting 53 from 98.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 53

Advancing to step 3:
When dividing 459 by 53, we get 8 with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 424 away from 459, we end up with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 53

Advancing to step 4:
The number 53 fits into 353 6 times, leaving a remainder of 35.
The next digit of our result is 6. 
Result so far: 186.0
If we subtract 318 from 353, we get 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 53

Going ahead to step 5:
53 goes into 355 6 times with a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 1866.0
If we take 318 away from 355, we end up with 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 53

Going ahead to step 6:
The number 53 fits into 372 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 18667.0
Subtracting 371 from 372 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
53 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 18667.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 53, we get 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 18667.01
Deduct 53 from 100 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
When dividing 470 by 53, we get 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 18667.018
If we subtract 424 from 470, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
53 can be fit into 460 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 18667.0188
Deduct 424 from 460 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 18667.0188 and a remainder of 0.00036.
