28721460 ÷ 377 
The aim is to understand the frequency of 377 in 28721460.

On to step 1:
The number 377 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 377

Let's proceed to step 2:
377 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 377

Moving on to step 3:
When dividing 287 by 377, we get 0 with a remainder of 287.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 287, we end up with 287.
Grab the next digit (2) from the dividend, add it to 287, then carry on: 2872 / 377

Step 4:
2872 divided by 377 is 7 with a remainder of 233.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 2639 from 2872, we get 233.
Include the next digit (1) from the dividend after 233, then repeat: 2331 / 377

Going ahead to step 5:
377 goes into 2331 6 times with a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we take 2262 away from 2331, we end up with 69.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 377

Going ahead to step 6:
377 goes into 694 1 times with a remainder of 317.
Put 1 as the next digit of the answer. 
Result so far: 761.0
Deduct 377 from 694 and we're left with 317.
Bring next digit (6) of the dividend behind the 317 and repeat the process: 3176 / 377

Going ahead to step 7:
377 goes into 3176 8 times with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 7618.0
Deduct 3016 from 3176 and we're left with 160.
Append the next digit (0) from the dividend to 160 and continue with: 1600 / 377

Going ahead to step 8:
The number 377 fits into 1600 4 times, leaving a remainder of 92.
Record the quotient 4 as the next digit in the result. 
Result so far: 76184.0
The remainder is 92 after subtracting 1508 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 9:
377 can be fit into 920 2 times, resulting in a remainder of 166.
The next digit of our result is 2. 
Result so far: 76184.2
The remainder is 166 after subtracting 754 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 10:
If we divide 1660 by 377, we get 4 and a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 76184.24
Deduct 1508 from 1660 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
1520 divided by 377 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 76184.244
If we subtract 1508 from 1520, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 76184.244 with a remainder of 0.0012.
