We look at the division of 28454189 by 377 
The aim is to understand the frequency of 377 in 28454189.

Step 1:
When dividing 2 by 377, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 377

On to step 2:
28 divided by 377 is 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 377

Step 3:
377 goes into 284 0 times with a remainder of 284.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 284 leaves us with 284.
Include the next digit (5) from the dividend after 284, then repeat: 2845 / 377

Step 4:
The number 377 fits into 2845 7 times, leaving a remainder of 206.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 2639 from 2845 and we're left with 206.
Append the next digit (4) from the dividend to 206 and continue with: 2064 / 377

Let's proceed to step 5:
377 can be fit into 2064 5 times, resulting in a remainder of 179.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 1885 from 2064 to get 179.
Append the next digit (1) from the dividend to 179 and continue with: 1791 / 377

Step 6:
If we divide 1791 by 377, we get 4 and a remainder of 283.
The number 4 becomes the next digit in our result. 
Result so far: 754.0
If we take 1508 away from 1791, we end up with 283.
Include the next digit (8) from the dividend after 283, then repeat: 2838 / 377

Going ahead to step 7:
When dividing 2838 by 377, we get 7 with a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 7547.0
Deduct 2639 from 2838 and we're left with 199.
Include the next digit (9) from the dividend after 199, then repeat: 1999 / 377

Advancing to step 8:
When dividing 1999 by 377, we get 5 with a remainder of 114.
The next digit of our result is 5. 
Result so far: 75475.0
The remainder is 114 after subtracting 1885 from 1999.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 9:
377 goes into 1140 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 75475.3
If we take 1131 away from 1140, we end up with 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 10:
377 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 75475.3
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
If we divide 900 by 377, we get 2 and a remainder of 146.
Record the quotient 2 as the next digit in the result. 
Result so far: 75475.302
If we take 754 away from 900, we end up 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.

On to step 12:
1460 divided by 377 is 3 with a remainder of 329.
Put 3 as the next digit of the answer. 
Result so far: 75475.3023
Deduct 1131 from 1460 and we're left with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 13:
When dividing 3290 by 377, we get 8 with a remainder of 274.
The next digit of our result is 8. 
Result so far: 75475.30238
If we take 3016 away from 3290, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 14:
377 goes into 2740 7 times with a remainder of 101.
Use 7 as the next digit of our solution. 
Result so far: 75475.302387
The remainder is 101 after subtracting 2639 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 15:
1010 divided by 377 is 2 with a remainder of 256.
The number 2 becomes the next digit in our result. 
Result so far: 75475.3023872
If we take 754 away from 1010, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
When dividing 2560 by 377, we get 6 with a remainder of 298.
Write down 6 as next digit of the result. 
Result so far: 75475.30238726
If we take 2262 away from 2560, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

The final outcome is 75475.30238726, with a leftover of 2.98e-07.
