We're dividing 15165533 by 377 
The aim is to understand the frequency of 377 in 15165533.

Going ahead to step 1:
If we divide 1 by 377, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 377

Going ahead to step 2:
When dividing 15 by 377, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 377

Advancing to step 3:
The number 377 fits into 151 0 times, leaving a remainder of 151.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 151, we get 151.
Include the next digit (6) from the dividend after 151, then repeat: 1516 / 377

Let's proceed to step 4:
If we divide 1516 by 377, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1508 from 1516 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 377

On to step 5:
377 can be fit into 85 0 times, resulting in a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
The remainder is 85 after subtracting 0 from 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 377

On to step 6:
If we divide 855 by 377, we get 2 and a remainder of 101.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
Deduct 754 from 855 and we're left with 101.
Take the next digit (3) from the dividend and append it to 101, then repeat: 1013 / 377

Let's proceed to step 7:
377 goes into 1013 2 times with a remainder of 259.
Write down 2 as next digit of the result. 
Result so far: 4022.0
Subtract 754 from 1013 to get 259.
Fetch the next digit (3) from the dividend, attach it to 259 and continue: 2593 / 377

Moving on to step 8:
The number 377 fits into 2593 6 times, leaving a remainder of 331.
Put 6 as the next digit of the answer. 
Result so far: 40226.0
Deduct 2262 from 2593 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 9:
377 can be fit into 3310 8 times, resulting in a remainder of 294.
The number 8 becomes the next digit in our result. 
Result so far: 40226.8
Deduct 3016 from 3310 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 10:
The number 377 fits into 2940 7 times, leaving a remainder of 301.
The number 7 becomes the next digit in our result. 
Result so far: 40226.87
If we take 2639 away from 2940, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 11:
If we divide 3010 by 377, we get 7 and a remainder of 371.
The number 7 becomes the next digit in our result. 
Result so far: 40226.877
If we take 2639 away from 3010, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Our division results in 40226.877 with a remaining 0.0371.
