We look at the division of 377161 by 76 
The aim is to understand the frequency of 76 in 377161.

Going ahead to step 1:
76 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 76

On to step 2:
37 divided by 76 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 76

Let's proceed to step 3:
When dividing 377 by 76, we get 4 with a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 304 from 377, we get 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 76

Moving on to step 4:
When dividing 731 by 76, we get 9 with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 47 after subtracting 684 from 731.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 76

Step 5:
When dividing 476 by 76, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 496.0
Deduct 456 from 476 and we're left with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 76

Let's proceed to step 6:
201 divided by 76 is 2 with a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 4962.0
The remainder is 49 after subtracting 152 from 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
If we divide 490 by 76, we get 6 and a remainder of 34.
The next digit of our result is 6. 
Result so far: 4962.6
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
When dividing 340 by 76, we get 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 4962.64
If we subtract 304 from 340, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
76 can be fit into 360 4 times, resulting in a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 4962.644
Deduct 304 from 360 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 4962.644 with a remainder of 0.0056.
