We're dividing 915626 by 53 
The aim is to understand the frequency of 53 in 915626.

On to step 1:
53 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 53

Advancing to step 2:
When dividing 91 by 53, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 53 from 91 and we're left with 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 53

Going ahead to step 3:
If we divide 385 by 53, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 371 from 385 leaves us with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 53

Let's proceed to step 4:
The number 53 fits into 146 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 172.0
The remainder is 40 after subtracting 106 from 146.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 53

Advancing to step 5:
If we divide 402 by 53, we get 7 and a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 1727.0
If we subtract 371 from 402, we get 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 53

Going ahead to step 6:
The number 53 fits into 316 5 times, leaving a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 17275.0
Subtracting 265 from 316 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
If we divide 510 by 53, we get 9 and a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 17275.9
If we subtract 477 from 510, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
53 goes into 330 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 17275.96
If we take 318 away from 330, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 53 fits into 120 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 17275.962
Deduct 106 from 120 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
140 divided by 53 is 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 17275.9622
Deduct 106 from 140 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 17275.9622, with a leftover of 0.00034.
