709178 divided by 53 
The aim is to understand the frequency of 53 in 709178.

Let's proceed to step 1:
53 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 53

Going ahead to step 2:
53 can be fit into 70 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 53 away from 70, we end up with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 53

Moving on to step 3:
The number 53 fits into 179 3 times, leaving a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 159 from 179 to get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 53

Moving on to step 4:
If we divide 201 by 53, we get 3 and a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
If we subtract 159 from 201, we get 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 53

Let's proceed to step 5:
427 divided by 53 is 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 1338.0
Deduct 424 from 427 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 53

Step 6:
53 can be fit into 38 0 times, resulting in a remainder of 38.
The next digit of our result is 0. 
Result so far: 13380.0
Subtract 0 from 38 to get 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 7:
The number 53 fits into 380 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 13380.7
Subtract 371 from 380 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
The number 53 fits into 90 1 times, leaving a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 13380.71
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.

Step 9:
53 goes into 370 6 times with a remainder of 52.
The next digit of our result is 6. 
Result so far: 13380.716
Subtracting 318 from 370 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
53 goes into 520 9 times with a remainder of 43.
The next digit of our result is 9. 
Result so far: 13380.7169
The remainder is 43 after subtracting 477 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
The number 53 fits into 430 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 13380.71698
Subtract 424 from 430 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
When dividing 60 by 53, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 13380.716981
Deduct 53 from 60 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
70 divided by 53 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 13380.7169811
Subtracting 53 from 70 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 13380.7169811 with a remainder of 1.7e-07.
