53851245 ÷ 727 
The aim is to understand the frequency of 727 in 53851245.

Let's proceed to step 1:
When dividing 5 by 727, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 727

On to step 2:
727 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 727

Advancing to step 3:
If we divide 538 by 727, we get 0 and a remainder of 538.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 538 after subtracting 0 from 538.
Fetch the next digit (5) from the dividend, attach it to 538 and continue: 5385 / 727

Advancing to step 4:
5385 divided by 727 is 7 with a remainder of 296.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 5089 from 5385 and we're left with 296.
Append the next digit (1) from the dividend to 296 and continue with: 2961 / 727

Going ahead to step 5:
The number 727 fits into 2961 4 times, leaving a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtract 2908 from 2961 to get 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 727

Advancing to step 6:
If we divide 532 by 727, we get 0 and a remainder of 532.
Record the quotient 0 as the next digit in the result. 
Result so far: 740.0
Subtracting 0 from 532 leaves us with 532.
Append the next digit (4) from the dividend to 532 and continue with: 5324 / 727

Let's proceed to step 7:
727 can be fit into 5324 7 times, resulting in a remainder of 235.
Record the quotient 7 as the next digit in the result. 
Result so far: 7407.0
Deduct 5089 from 5324 and we're left with 235.
Include the next digit (5) from the dividend after 235, then repeat: 2355 / 727

Moving on to step 8:
2355 divided by 727 is 3 with a remainder of 174.
Put 3 as the next digit of the answer. 
Result so far: 74073.0
Subtract 2181 from 2355 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 9:
727 goes into 1740 2 times with a remainder of 286.
Put 2 as the next digit of the answer. 
Result so far: 74073.2
Subtracting 1454 from 1740 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 10:
When dividing 2860 by 727, we get 3 with a remainder of 679.
Put 3 as the next digit of the answer. 
Result so far: 74073.23
If we subtract 2181 from 2860, we get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Moving on to step 11:
727 goes into 6790 9 times with a remainder of 247.
Write down 9 as next digit of the result. 
Result so far: 74073.239
If we subtract 6543 from 6790, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 12:
727 can be fit into 2470 3 times, resulting in a remainder of 289.
Record the quotient 3 as the next digit in the result. 
Result so far: 74073.2393
Subtract 2181 from 2470 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 13:
727 can be fit into 2890 3 times, resulting in a remainder of 709.
Use 3 as the next digit of our solution. 
Result so far: 74073.23933
Subtracting 2181 from 2890 leaves us with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

The quotient of the division is 74073.23933, and the remainder is 0.000709.
