We look at the division of 5437992 by 513 
The aim is to understand the frequency of 513 in 5437992.

Step 1:
5 divided by 513 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 513

Let's proceed to step 2:
If we divide 54 by 513, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 513

Step 3:
513 can be fit into 543 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 513 from 543, we get 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 513

Advancing to step 4:
If we divide 307 by 513, we get 0 and a remainder of 307.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 307 after subtracting 0 from 307.
Fetch the next digit (9) from the dividend, attach it to 307 and continue: 3079 / 513

On to step 5:
The number 513 fits into 3079 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 106.0
Deduct 3078 from 3079 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 513

Let's proceed to step 6:
If we divide 19 by 513, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 1060.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 513

Let's proceed to step 7:
192 divided by 513 is 0 with a remainder of 192.
Put 0 as the next digit of the answer. 
Result so far: 10600.0
Deduct 0 from 192 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 8:
The number 513 fits into 1920 3 times, leaving a remainder of 381.
Record the quotient 3 as the next digit in the result. 
Result so far: 10600.3
Subtracting 1539 from 1920 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 9:
513 can be fit into 3810 7 times, resulting in a remainder of 219.
The next digit of our result is 7. 
Result so far: 10600.37
If we subtract 3591 from 3810, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 10:
If we divide 2190 by 513, we get 4 and a remainder of 138.
Put 4 as the next digit of the answer. 
Result so far: 10600.374
If we take 2052 away from 2190, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 11:
513 goes into 1380 2 times with a remainder of 354.
Write down 2 as next digit of the result. 
Result so far: 10600.3742
Subtracting 1026 from 1380 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 12:
513 can be fit into 3540 6 times, resulting in a remainder of 462.
Put 6 as the next digit of the answer. 
Result so far: 10600.37426
Subtract 3078 from 3540 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 13:
513 can be fit into 4620 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 10600.374269
Deduct 4617 from 4620 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
The number 513 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10600.374269
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 15:
The number 513 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 10600.374269
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 10600.374269 with a remainder of 3e-07.
