Let's divide 39520616 by 377
The aim is to understand the frequency of 377 in 39520616.

On to step 1:
377 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 377

Going ahead to step 2:
377 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 377

On to step 3:
The number 377 fits into 395 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 377 from 395, we get 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 377

Moving on to step 4:
377 can be fit into 182 0 times, resulting in a remainder of 182.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 182, we get 182.
Fetch the next digit (0) from the dividend, attach it to 182 and continue: 1820 / 377

Advancing to step 5:
1820 divided by 377 is 4 with a remainder of 312.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 1508 from 1820, we get 312.
Bring next digit (6) of the dividend behind the 312 and repeat the process: 3126 / 377

On to step 6:
377 goes into 3126 8 times with a remainder of 110.
Record the quotient 8 as the next digit in the result. 
Result so far: 1048.0
Deduct 3016 from 3126 and we're left with 110.
Append the next digit (1) from the dividend to 110 and continue with: 1101 / 377

Moving on to step 7:
The number 377 fits into 1101 2 times, leaving a remainder of 347.
The number 2 becomes the next digit in our result. 
Result so far: 10482.0
Subtracting 754 from 1101 leaves us with 347.
Fetch the next digit (6) from the dividend, attach it to 347 and continue: 3476 / 377

On to step 8:
3476 divided by 377 is 9 with a remainder of 83.
The next digit of our result is 9. 
Result so far: 104829.0
If we take 3393 away from 3476, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 9:
377 can be fit into 830 2 times, resulting in a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 104829.2
The remainder is 76 after subtracting 754 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
760 divided by 377 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 104829.22
If we take 754 away from 760, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 104829.22, and the remainder is 0.006.
