37043991 ÷ 377 
The aim is to understand the frequency of 377 in 37043991.

On to step 1:
377 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 377

On to step 2:
377 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 377

Advancing to step 3:
If we divide 370 by 377, we get 0 and a remainder of 370.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 370 and we're left with 370.
Fetch the next digit (4) from the dividend, attach it to 370 and continue: 3704 / 377

Step 4:
The number 377 fits into 3704 9 times, leaving a remainder of 311.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 3393 from 3704 leaves us with 311.
Take the next digit (3) from the dividend and append it to 311, then repeat: 3113 / 377

Advancing to step 5:
When dividing 3113 by 377, we get 8 with a remainder of 97.
The next digit of our result is 8. 
Result so far: 98.0
If we subtract 3016 from 3113, we get 97.
Fetch the next digit (9) from the dividend, attach it to 97 and continue: 979 / 377

Step 6:
When dividing 979 by 377, we get 2 with a remainder of 225.
Put 2 as the next digit of the answer. 
Result so far: 982.0
If we subtract 754 from 979, we get 225.
Include the next digit (9) from the dividend after 225, then repeat: 2259 / 377

Step 7:
2259 divided by 377 is 5 with a remainder of 374.
The number 5 becomes the next digit in our result. 
Result so far: 9825.0
Deduct 1885 from 2259 and we're left with 374.
Append the next digit (1) from the dividend to 374 and continue with: 3741 / 377

Advancing to step 8:
3741 divided by 377 is 9 with a remainder of 348.
Record the quotient 9 as the next digit in the result. 
Result so far: 98259.0
If we subtract 3393 from 3741, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
The number 377 fits into 3480 9 times, leaving a remainder of 87.
The next digit of our result is 9. 
Result so far: 98259.9
Subtract 3393 from 3480 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 10:
When dividing 870 by 377, we get 2 with a remainder of 116.
The next digit of our result is 2. 
Result so far: 98259.92
If we take 754 away from 870, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 11:
The number 377 fits into 1160 3 times, leaving a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 98259.923
Deduct 1131 from 1160 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
When dividing 290 by 377, we get 0 with a remainder of 290.
The next digit of our result is 0. 
Result so far: 98259.923
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 13:
If we divide 2900 by 377, we get 7 and a remainder of 261.
The next digit of our result is 7. 
Result so far: 98259.92307
If we subtract 2639 from 2900, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 14:
If we divide 2610 by 377, we get 6 and a remainder of 348.
Write down 6 as next digit of the result. 
Result so far: 98259.923076
Deduct 2262 from 2610 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 15:
If we divide 3480 by 377, we get 9 and a remainder of 87.
Write down 9 as next digit of the result. 
Result so far: 98259.9230769
Subtract 3393 from 3480 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 16:
When dividing 870 by 377, we get 2 with a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 98259.92307692
Subtracting 754 from 870 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final result is 98259.92307692 with a remainder of 1.16e-07.
