519120 ÷ 53 
The aim is to understand the frequency of 53 in 519120.

Going ahead to step 1:
53 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 53

On to step 2:
53 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 53

On to step 3:
The number 53 fits into 519 9 times, leaving a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 477 from 519 to get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 53

Step 4:
The number 53 fits into 421 7 times, leaving a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 97.0
The remainder is 50 after subtracting 371 from 421.
Fetch the next digit (2) from the dividend, attach it to 50 and continue: 502 / 53

Advancing to step 5:
When dividing 502 by 53, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 979.0
Subtract 477 from 502 to get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 53

On to step 6:
If we divide 250 by 53, we get 4 and a remainder of 38.
The next digit of our result is 4. 
Result so far: 9794.0
Subtract 212 from 250 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.

Step 7:
380 divided by 53 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 9794.7
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:
If we divide 90 by 53, we get 1 and a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 9794.71
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.

Advancing to step 9:
The number 53 fits into 370 6 times, leaving a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 9794.716
If we take 318 away from 370, we end up 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.

Step 10:
520 divided by 53 is 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 9794.7169
If we take 477 away from 520, we end up 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.

Going ahead to step 11:
The number 53 fits into 430 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 9794.71698
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.

Going ahead to step 12:
53 can be fit into 60 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 9794.716981
Subtract 53 from 60 to 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.

Advancing to step 13:
53 goes into 70 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 9794.7169811
The remainder is 17 after subtracting 53 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 9794.7169811 with a remaining 1.7e-07.
