We're dividing 63100436 by 513 
The aim is to understand the frequency of 513 in 63100436.

Moving on to step 1:
If we divide 6 by 513, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 513

Let's proceed to step 2:
When dividing 63 by 513, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 513

Step 3:
The number 513 fits into 631 1 times, leaving a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 513 from 631, we get 118.
Grab the next digit (0) from the dividend, add it to 118, then carry on: 1180 / 513

Going ahead to step 4:
If we divide 1180 by 513, we get 2 and a remainder of 154.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1026 from 1180 and we're left with 154.
Bring next digit (0) of the dividend behind the 154 and repeat the process: 1540 / 513

Step 5:
If we divide 1540 by 513, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 123.0
If we take 1539 away from 1540, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 513

Going ahead to step 6:
When dividing 14 by 513, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 1230.0
If we subtract 0 from 14, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 513

Advancing to step 7:
513 goes into 143 0 times with a remainder of 143.
Write down 0 as next digit of the result. 
Result so far: 12300.0
Subtract 0 from 143 to get 143.
Grab the next digit (6) from the dividend, add it to 143, then carry on: 1436 / 513

Let's proceed to step 8:
1436 divided by 513 is 2 with a remainder of 410.
Write down 2 as next digit of the result. 
Result so far: 123002.0
Subtracting 1026 from 1436 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 9:
513 goes into 4100 7 times with a remainder of 509.
The next digit of our result is 7. 
Result so far: 123002.7
Subtracting 3591 from 4100 leaves us with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Let's proceed to step 10:
513 can be fit into 5090 9 times, resulting in a remainder of 473.
Put 9 as the next digit of the answer. 
Result so far: 123002.79
The remainder is 473 after subtracting 4617 from 5090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

On to step 11:
The number 513 fits into 4730 9 times, leaving a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 123002.799
If we subtract 4617 from 4730, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

The final outcome is 123002.799, with a leftover of 0.0113.
