915339 ÷ 53 
The aim is to understand the frequency of 53 in 915339.

Advancing to step 1:
When dividing 9 by 53, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 53

Going ahead to step 2:
If we divide 91 by 53, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 53 from 91 to get 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 53

On to step 3:
385 divided by 53 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 371 from 385 and we're left with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 53

On to step 4:
53 can be fit into 143 2 times, resulting in a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtracting 106 from 143 leaves us with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 53

Moving on to step 5:
If we divide 373 by 53, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 1727.0
Subtracting 371 from 373 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 53

Step 6:
53 goes into 29 0 times with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 17270.0
The remainder is 29 after subtracting 0 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
53 can be fit into 290 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 17270.5
Subtracting 265 from 290 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.

Let's proceed to step 8:
53 goes into 250 4 times with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 17270.54
Subtracting 212 from 250 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
The number 53 fits into 380 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 17270.547
If we take 371 away from 380, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
The number 53 fits into 90 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 17270.5471
Subtracting 53 from 90 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
53 goes into 370 6 times with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 17270.54716
Subtract 318 from 370 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
The number 53 fits into 520 9 times, leaving a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 17270.547169
Subtracting 477 from 520 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 13:
If we divide 430 by 53, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 17270.5471698
If we take 424 away from 430, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
When dividing 60 by 53, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 17270.54716981
If we subtract 53 from 60, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 17270.54716981 and a remainder of 7e-09.
