We're dividing 1386572 by 277 
The aim is to understand the frequency of 277 in 1386572.

On to step 1:
277 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 277

On to step 2:
When dividing 13 by 277, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 277

Advancing to step 3:
138 divided by 277 is 0 with a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 138 leaves us with 138.
Include the next digit (6) from the dividend after 138, then repeat: 1386 / 277

Let's proceed to step 4:
When dividing 1386 by 277, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 1385 from 1386 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 277

On to step 5:
277 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 277

On to step 6:
157 divided by 277 is 0 with a remainder of 157.
Put 0 as the next digit of the answer. 
Result so far: 500.0
Deduct 0 from 157 and we're left with 157.
Append the next digit (2) from the dividend to 157 and continue with: 1572 / 277

On to step 7:
277 goes into 1572 5 times with a remainder of 187.
The number 5 becomes the next digit in our result. 
Result so far: 5005.0
If we subtract 1385 from 1572, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 8:
The number 277 fits into 1870 6 times, leaving a remainder of 208.
The next digit of our result is 6. 
Result so far: 5005.6
Subtracting 1662 from 1870 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 9:
If we divide 2080 by 277, we get 7 and a remainder of 141.
Put 7 as the next digit of the answer. 
Result so far: 5005.67
Subtract 1939 from 2080 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 10:
277 can be fit into 1410 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 5005.675
Subtracting 1385 from 1410 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
The number 277 fits into 250 0 times, leaving a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 5005.675
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 12:
277 goes into 2500 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 5005.67509
Subtracting 2493 from 2500 leaves us 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.

Let's proceed to step 13:
277 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 5005.67509
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
277 goes into 700 2 times with a remainder of 146.
The number 2 becomes the next digit in our result. 
Result so far: 5005.6750902
Deduct 554 from 700 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 15:
The number 277 fits into 1460 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 5005.67509025
If we subtract 1385 from 1460, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 5005.67509025, and the remainder is 7.5e-08.
