13888487 ÷ 510 
The aim is to understand the frequency of 510 in 13888487.

Advancing to step 1:
When dividing 1 by 510, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 510

On to step 2:
510 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 510

Let's proceed to step 3:
When dividing 138 by 510, we get 0 with a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 138 and we're left with 138.
Fetch the next digit (8) from the dividend, attach it to 138 and continue: 1388 / 510

Let's proceed to step 4:
When dividing 1388 by 510, we get 2 with a remainder of 368.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1020 from 1388, we get 368.
Grab the next digit (8) from the dividend, add it to 368, then carry on: 3688 / 510

Advancing to step 5:
When dividing 3688 by 510, we get 7 with a remainder of 118.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we subtract 3570 from 3688, we get 118.
Bring next digit (4) of the dividend behind the 118 and repeat the process: 1184 / 510

Moving on to step 6:
510 can be fit into 1184 2 times, resulting in a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 272.0
Subtract 1020 from 1184 to get 164.
Append the next digit (8) from the dividend to 164 and continue with: 1648 / 510

Let's proceed to step 7:
If we divide 1648 by 510, we get 3 and a remainder of 118.
Write down 3 as next digit of the result. 
Result so far: 2723.0
Subtract 1530 from 1648 to get 118.
Bring next digit (7) of the dividend behind the 118 and repeat the process: 1187 / 510

Moving on to step 8:
If we divide 1187 by 510, we get 2 and a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 27232.0
Subtracting 1020 from 1187 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 9:
510 can be fit into 1670 3 times, resulting in a remainder of 140.
Write down 3 as next digit of the result. 
Result so far: 27232.3
Deduct 1530 from 1670 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
The number 510 fits into 1400 2 times, leaving a remainder of 380.
Record the quotient 2 as the next digit in the result. 
Result so far: 27232.32
Subtract 1020 from 1400 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 11:
510 goes into 3800 7 times with a remainder of 230.
Use 7 as the next digit of our solution. 
Result so far: 27232.327
If we subtract 3570 from 3800, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 12:
If we divide 2300 by 510, we get 4 and a remainder of 260.
Use 4 as the next digit of our solution. 
Result so far: 27232.3274
If we subtract 2040 from 2300, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 13:
510 goes into 2600 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 27232.32745
Subtracting 2550 from 2600 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
When dividing 500 by 510, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 27232.32745
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 15:
510 can be fit into 5000 9 times, resulting in a remainder of 410.
The next digit of our result is 9. 
Result so far: 27232.3274509
The remainder is 410 after subtracting 4590 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 16:
510 goes into 4100 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 27232.32745098
The remainder is 20 after subtracting 4080 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 27232.32745098, with a leftover of 2e-08.
