4351448 divided by 513 
The aim is to understand the frequency of 513 in 4351448.

Going ahead to step 1:
The number 513 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 513

Step 2:
43 divided by 513 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 513

Let's proceed to step 3:
If we divide 435 by 513, we get 0 and a remainder of 435.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 435 after subtracting 0 from 435.
Bring next digit (1) of the dividend behind the 435 and repeat the process: 4351 / 513

Step 4:
If we divide 4351 by 513, we get 8 and a remainder of 247.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 4104 from 4351, we get 247.
Take the next digit (4) from the dividend and append it to 247, then repeat: 2474 / 513

Moving on to step 5:
If we divide 2474 by 513, we get 4 and a remainder of 422.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Deduct 2052 from 2474 and we're left with 422.
Take the next digit (4) from the dividend and append it to 422, then repeat: 4224 / 513

Advancing to step 6:
If we divide 4224 by 513, we get 8 and a remainder of 120.
The next digit of our result is 8. 
Result so far: 848.0
Subtracting 4104 from 4224 leaves us with 120.
Append the next digit (8) from the dividend to 120 and continue with: 1208 / 513

Step 7:
The number 513 fits into 1208 2 times, leaving a remainder of 182.
The number 2 becomes the next digit in our result. 
Result so far: 8482.0
If we take 1026 away from 1208, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 8:
513 can be fit into 1820 3 times, resulting in a remainder of 281.
The next digit of our result is 3. 
Result so far: 8482.3
If we take 1539 away from 1820, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 9:
513 can be fit into 2810 5 times, resulting in a remainder of 245.
Use 5 as the next digit of our solution. 
Result so far: 8482.35
If we take 2565 away from 2810, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 10:
If we divide 2450 by 513, we get 4 and a remainder of 398.
Put 4 as the next digit of the answer. 
Result so far: 8482.354
The remainder is 398 after subtracting 2052 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 11:
The number 513 fits into 3980 7 times, leaving a remainder of 389.
Record the quotient 7 as the next digit in the result. 
Result so far: 8482.3547
If we take 3591 away from 3980, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 12:
When dividing 3890 by 513, we get 7 with a remainder of 299.
Write down 7 as next digit of the result. 
Result so far: 8482.35477
Subtract 3591 from 3890 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.

The quotient of the division is 8482.35477, and the remainder is 0.000299.
