Let's divide 16581523 by 376
The aim is to understand the frequency of 376 in 16581523.

Let's proceed to step 1:
1 divided by 376 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 376

Step 2:
16 divided by 376 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 376

Advancing to step 3:
If we divide 165 by 376, we get 0 and a remainder of 165.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 165 after subtracting 0 from 165.
Take the next digit (8) from the dividend and append it to 165, then repeat: 1658 / 376

Advancing to step 4:
376 can be fit into 1658 4 times, resulting in a remainder of 154.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1504 from 1658 to get 154.
Fetch the next digit (1) from the dividend, attach it to 154 and continue: 1541 / 376

On to step 5:
376 can be fit into 1541 4 times, resulting in a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 1504 from 1541, we get 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 376

Going ahead to step 6:
The number 376 fits into 375 0 times, leaving a remainder of 375.
The number 0 becomes the next digit in our result. 
Result so far: 440.0
If we subtract 0 from 375, we get 375.
Bring next digit (2) of the dividend behind the 375 and repeat the process: 3752 / 376

Going ahead to step 7:
If we divide 3752 by 376, we get 9 and a remainder of 368.
Write down 9 as next digit of the result. 
Result so far: 4409.0
If we take 3384 away from 3752, we end up with 368.
Fetch the next digit (3) from the dividend, attach it to 368 and continue: 3683 / 376

Let's proceed to step 8:
3683 divided by 376 is 9 with a remainder of 299.
Record the quotient 9 as the next digit in the result. 
Result so far: 44099.0
Subtract 3384 from 3683 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 9:
When dividing 2990 by 376, we get 7 with a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 44099.7
Deduct 2632 from 2990 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 10:
The number 376 fits into 3580 9 times, leaving a remainder of 196.
The next digit of our result is 9. 
Result so far: 44099.79
Subtract 3384 from 3580 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 11:
If we divide 1960 by 376, we get 5 and a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 44099.795
If we take 1880 away from 1960, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
The number 376 fits into 800 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 44099.7952
Deduct 752 from 800 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
When dividing 480 by 376, we get 1 with a remainder of 104.
Use 1 as the next digit of our solution. 
Result so far: 44099.79521
Subtracting 376 from 480 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 14:
376 can be fit into 1040 2 times, resulting in a remainder of 288.
The next digit of our result is 2. 
Result so far: 44099.795212
If we subtract 752 from 1040, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 15:
The number 376 fits into 2880 7 times, leaving a remainder of 248.
The number 7 becomes the next digit in our result. 
Result so far: 44099.7952127
If we subtract 2632 from 2880, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 16:
The number 376 fits into 2480 6 times, leaving a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 44099.79521276
The remainder is 224 after subtracting 2256 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final outcome is 44099.79521276, with a leftover of 2.24e-07.
