We look at the division of 4391340 by 377 
The aim is to understand the frequency of 377 in 4391340.

Advancing to step 1:
If we divide 4 by 377, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 377

Going ahead to step 2:
The number 377 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 377

Let's proceed to step 3:
377 can be fit into 439 1 times, resulting in a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 377 from 439 to get 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 377

Going ahead to step 4:
377 goes into 621 1 times with a remainder of 244.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 377 away from 621, we end up with 244.
Bring next digit (3) of the dividend behind the 244 and repeat the process: 2443 / 377

Going ahead to step 5:
377 can be fit into 2443 6 times, resulting in a remainder of 181.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we subtract 2262 from 2443, we get 181.
Append the next digit (4) from the dividend to 181 and continue with: 1814 / 377

Advancing to step 6:
377 goes into 1814 4 times with a remainder of 306.
The number 4 becomes the next digit in our result. 
Result so far: 1164.0
If we take 1508 away from 1814, we end up with 306.
Bring next digit (0) of the dividend behind the 306 and repeat the process: 3060 / 377

Step 7:
If we divide 3060 by 377, we get 8 and a remainder of 44.
The next digit of our result is 8. 
Result so far: 11648.0
If we subtract 3016 from 3060, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
If we divide 440 by 377, we get 1 and a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 11648.1
The remainder is 63 after subtracting 377 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 9:
377 can be fit into 630 1 times, resulting in a remainder of 253.
Write down 1 as next digit of the result. 
Result so far: 11648.11
If we subtract 377 from 630, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

In conclusion, the division gives 11648.11 with a balance of 0.253.
