We look at the division of 42147683 by 510 
The aim is to understand the frequency of 510 in 42147683.

Going ahead to step 1:
510 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 510

Going ahead to step 2:
The number 510 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 510

On to step 3:
The number 510 fits into 421 0 times, leaving a remainder of 421.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 421 after subtracting 0 from 421.
Fetch the next digit (4) from the dividend, attach it to 421 and continue: 4214 / 510

Moving on to step 4:
The number 510 fits into 4214 8 times, leaving a remainder of 134.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 134 after subtracting 4080 from 4214.
Append the next digit (7) from the dividend to 134 and continue with: 1347 / 510

Step 5:
510 can be fit into 1347 2 times, resulting in a remainder of 327.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtracting 1020 from 1347 leaves us with 327.
Grab the next digit (6) from the dividend, add it to 327, then carry on: 3276 / 510

Moving on to step 6:
If we divide 3276 by 510, we get 6 and a remainder of 216.
Record the quotient 6 as the next digit in the result. 
Result so far: 826.0
The remainder is 216 after subtracting 3060 from 3276.
Bring next digit (8) of the dividend behind the 216 and repeat the process: 2168 / 510

Moving on to step 7:
If we divide 2168 by 510, we get 4 and a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 8264.0
If we take 2040 away from 2168, we end up with 128.
Include the next digit (3) from the dividend after 128, then repeat: 1283 / 510

Moving on to step 8:
If we divide 1283 by 510, we get 2 and a remainder of 263.
The number 2 becomes the next digit in our result. 
Result so far: 82642.0
Subtracting 1020 from 1283 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 9:
510 goes into 2630 5 times with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 82642.5
If we subtract 2550 from 2630, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
When dividing 800 by 510, we get 1 with a remainder of 290.
Write down 1 as next digit of the result. 
Result so far: 82642.51
If we take 510 away from 800, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 11:
510 can be fit into 2900 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 82642.515
The remainder is 350 after subtracting 2550 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 12:
The number 510 fits into 3500 6 times, leaving a remainder of 440.
The next digit of our result is 6. 
Result so far: 82642.5156
If we subtract 3060 from 3500, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 13:
When dividing 4400 by 510, we get 8 with a remainder of 320.
Write down 8 as next digit of the result. 
Result so far: 82642.51568
Subtract 4080 from 4400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 14:
3200 divided by 510 is 6 with a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 82642.515686
The remainder is 140 after subtracting 3060 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 15:
The number 510 fits into 1400 2 times, leaving a remainder of 380.
Write down 2 as next digit of the result. 
Result so far: 82642.5156862
Deduct 1020 from 1400 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 16:
3800 divided by 510 is 7 with a remainder of 230.
The next digit of our result is 7. 
Result so far: 82642.51568627
The remainder is 230 after subtracting 3570 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Our division results in 82642.51568627 with a remaining 2.3e-07.
