Let's divide 902573 by 53
The aim is to understand the frequency of 53 in 902573.

Step 1:
If we divide 9 by 53, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 53

Going ahead to step 2:
90 divided by 53 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 53 away from 90, we end up with 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 53

Step 3:
If we divide 372 by 53, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 371 away from 372, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 53

Let's proceed to step 4:
15 divided by 53 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 170.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 53

Advancing to step 5:
The number 53 fits into 157 2 times, leaving a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 1702.0
Subtracting 106 from 157 leaves us with 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 53

Step 6:
The number 53 fits into 513 9 times, leaving a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 17029.0
Deduct 477 from 513 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.

Going ahead to step 7:
The number 53 fits into 360 6 times, leaving a remainder of 42.
The next digit of our result is 6. 
Result so far: 17029.6
If we subtract 318 from 360, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
420 divided by 53 is 7 with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 17029.67
The remainder is 49 after subtracting 371 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
If we divide 490 by 53, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 17029.679
The remainder is 13 after subtracting 477 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
If we divide 130 by 53, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 17029.6792
The remainder is 24 after subtracting 106 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
When dividing 240 by 53, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 17029.67924
Subtract 212 from 240 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
53 can be fit into 280 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 17029.679245
The remainder is 15 after subtracting 265 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
53 goes into 150 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 17029.6792452
Deduct 106 from 150 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
53 can be fit into 440 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 17029.67924528
If we subtract 424 from 440, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 17029.67924528, and the remainder is 1.6e-08.
