99784529 ÷ 376 
The aim is to understand the frequency of 376 in 99784529.

Advancing to step 1:
When dividing 9 by 376, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 376

Let's proceed to step 2:
99 divided by 376 is 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Fetch the next digit (7) from the dividend, attach it to 99 and continue: 997 / 376

Going ahead to step 3:
When dividing 997 by 376, we get 2 with a remainder of 245.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 245 after subtracting 752 from 997.
Bring next digit (8) of the dividend behind the 245 and repeat the process: 2458 / 376

Moving on to step 4:
376 can be fit into 2458 6 times, resulting in a remainder of 202.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 2256 from 2458 to get 202.
Bring next digit (4) of the dividend behind the 202 and repeat the process: 2024 / 376

Let's proceed to step 5:
2024 divided by 376 is 5 with a remainder of 144.
Put 5 as the next digit of the answer. 
Result so far: 265.0
Deduct 1880 from 2024 and we're left with 144.
Grab the next digit (5) from the dividend, add it to 144, then carry on: 1445 / 376

Advancing to step 6:
376 goes into 1445 3 times with a remainder of 317.
The next digit of our result is 3. 
Result so far: 2653.0
If we subtract 1128 from 1445, we get 317.
Include the next digit (2) from the dividend after 317, then repeat: 3172 / 376

Moving on to step 7:
376 can be fit into 3172 8 times, resulting in a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 26538.0
If we subtract 3008 from 3172, we get 164.
Take the next digit (9) from the dividend and append it to 164, then repeat: 1649 / 376

On to step 8:
If we divide 1649 by 376, we get 4 and a remainder of 145.
Record the quotient 4 as the next digit in the result. 
Result so far: 265384.0
Subtracting 1504 from 1649 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 9:
If we divide 1450 by 376, we get 3 and a remainder of 322.
Use 3 as the next digit of our solution. 
Result so far: 265384.3
If we take 1128 away from 1450, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 10:
376 goes into 3220 8 times with a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 265384.38
Subtract 3008 from 3220 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 11:
If we divide 2120 by 376, we get 5 and a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 265384.385
Subtract 1880 from 2120 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
The number 376 fits into 2400 6 times, leaving a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 265384.3856
Deduct 2256 from 2400 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
376 can be fit into 1440 3 times, resulting in a remainder of 312.
The number 3 becomes the next digit in our result. 
Result so far: 265384.38563
If we subtract 1128 from 1440, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 14:
376 goes into 3120 8 times with a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 265384.385638
If we subtract 3008 from 3120, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 15:
1120 divided by 376 is 2 with a remainder of 368.
Record the quotient 2 as the next digit in the result. 
Result so far: 265384.3856382
Subtract 752 from 1120 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 16:
3680 divided by 376 is 9 with a remainder of 296.
The number 9 becomes the next digit in our result. 
Result so far: 265384.38563829
Deduct 3384 from 3680 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 265384.38563829, with a leftover of 2.96e-07.
