We look at the division of 898155 by 53 
The aim is to understand the frequency of 53 in 898155.

Let's proceed to step 1:
When dividing 8 by 53, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 53

On to step 2:
If we divide 89 by 53, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 53 from 89 and we're left with 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 53

Advancing to step 3:
368 divided by 53 is 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 318 from 368 to get 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 53

Let's proceed to step 4:
When dividing 501 by 53, we get 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 169.0
The remainder is 24 after subtracting 477 from 501.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 53

Moving on to step 5:
If we divide 245 by 53, we get 4 and a remainder of 33.
The next digit of our result is 4. 
Result so far: 1694.0
If we take 212 away from 245, we end up with 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 53

Let's proceed to step 6:
53 goes into 335 6 times with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 16946.0
Subtract 318 from 335 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
The number 53 fits into 170 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 16946.3
Subtract 159 from 170 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
If we divide 110 by 53, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 16946.32
Deduct 106 from 110 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 53, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 16946.32
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
400 divided by 53 is 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 16946.3207
Deduct 371 from 400 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
If we divide 290 by 53, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 16946.32075
If we subtract 265 from 290, we get 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 12:
When dividing 250 by 53, we get 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 16946.320754
If we take 212 away from 250, we end up 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.

Moving on to step 13:
If we divide 380 by 53, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 16946.3207547
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.

On to step 14:
When dividing 90 by 53, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 16946.32075471
Subtract 53 from 90 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 16946.32075471 with a remainder of 3.7e-08.
