1663461 divided by 513 
The aim is to understand the frequency of 513 in 1663461.

Advancing to step 1:
513 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 513

Moving on to step 2:
16 divided by 513 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 513

Step 3:
513 goes into 166 0 times with a remainder of 166.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 166 and we're left with 166.
Bring next digit (3) of the dividend behind the 166 and repeat the process: 1663 / 513

Moving on to step 4:
513 can be fit into 1663 3 times, resulting in a remainder of 124.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 124 after subtracting 1539 from 1663.
Grab the next digit (4) from the dividend, add it to 124, then carry on: 1244 / 513

Moving on to step 5:
1244 divided by 513 is 2 with a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 1026 from 1244 to get 218.
Grab the next digit (6) from the dividend, add it to 218, then carry on: 2186 / 513

On to step 6:
The number 513 fits into 2186 4 times, leaving a remainder of 134.
Put 4 as the next digit of the answer. 
Result so far: 324.0
Subtract 2052 from 2186 to get 134.
Include the next digit (1) from the dividend after 134, then repeat: 1341 / 513

Going ahead to step 7:
When dividing 1341 by 513, we get 2 with a remainder of 315.
Record the quotient 2 as the next digit in the result. 
Result so far: 3242.0
Subtract 1026 from 1341 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 8:
When dividing 3150 by 513, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 3242.6
Deduct 3078 from 3150 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
The number 513 fits into 720 1 times, leaving a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 3242.61
Subtract 513 from 720 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 10:
513 goes into 2070 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 3242.614
If we take 2052 away from 2070, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
If we divide 180 by 513, we get 0 and a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 3242.614
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 12:
513 goes into 1800 3 times with a remainder of 261.
Use 3 as the next digit of our solution. 
Result so far: 3242.61403
Deduct 1539 from 1800 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 13:
When dividing 2610 by 513, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 3242.614035
Deduct 2565 from 2610 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
When dividing 450 by 513, we get 0 with a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 3242.614035
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 15:
If we divide 4500 by 513, we get 8 and a remainder of 396.
The next digit of our result is 8. 
Result so far: 3242.61403508
Deduct 4104 from 4500 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The quotient of the division is 3242.61403508, and the remainder is 3.96e-07.
