We look at the division of 87720133 by 277 
The aim is to understand the frequency of 277 in 87720133.

On to step 1:
If we divide 8 by 277, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 277

Advancing to step 2:
The number 277 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Include the next digit (7) from the dividend after 87, then repeat: 877 / 277

Going ahead to step 3:
877 divided by 277 is 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 831 from 877 to get 46.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 277

Step 4:
The number 277 fits into 462 1 times, leaving a remainder of 185.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 277 from 462 to get 185.
Include the next digit (0) from the dividend after 185, then repeat: 1850 / 277

Advancing to step 5:
277 can be fit into 1850 6 times, resulting in a remainder of 188.
Use 6 as the next digit of our solution. 
Result so far: 316.0
Subtracting 1662 from 1850 leaves us with 188.
Fetch the next digit (1) from the dividend, attach it to 188 and continue: 1881 / 277

On to step 6:
When dividing 1881 by 277, we get 6 with a remainder of 219.
Use 6 as the next digit of our solution. 
Result so far: 3166.0
Deduct 1662 from 1881 and we're left with 219.
Bring next digit (3) of the dividend behind the 219 and repeat the process: 2193 / 277

Advancing to step 7:
The number 277 fits into 2193 7 times, leaving a remainder of 254.
The next digit of our result is 7. 
Result so far: 31667.0
If we subtract 1939 from 2193, we get 254.
Take the next digit (3) from the dividend and append it to 254, then repeat: 2543 / 277

On to step 8:
If we divide 2543 by 277, we get 9 and a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 316679.0
Subtract 2493 from 2543 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
The number 277 fits into 500 1 times, leaving a remainder of 223.
Record the quotient 1 as the next digit in the result. 
Result so far: 316679.1
Subtracting 277 from 500 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 10:
2230 divided by 277 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 316679.18
Deduct 2216 from 2230 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
The number 277 fits into 140 0 times, leaving a remainder of 140.
The next digit of our result is 0. 
Result so far: 316679.18
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 12:
277 can be fit into 1400 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 316679.1805
If we take 1385 away from 1400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
277 can be fit into 150 0 times, resulting in a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 316679.1805
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 14:
1500 divided by 277 is 5 with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 316679.180505
Subtract 1385 from 1500 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 15:
The number 277 fits into 1150 4 times, leaving a remainder of 42.
The next digit of our result is 4. 
Result so far: 316679.1805054
If we take 1108 away from 1150, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 16:
When dividing 420 by 277, we get 1 with a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 316679.18050541
If we take 277 away from 420, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final result is 316679.18050541 with a remainder of 1.43e-07.
