We divide 531019 by 51
The aim is to understand the frequency of 51 in 531019.

On to step 1:
5 divided by 51 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 51

Let's proceed to step 2:
53 divided by 51 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 51 from 53.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 51

Going ahead to step 3:
When dividing 21 by 51, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 51

On to step 4:
210 divided by 51 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Deduct 204 from 210 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 51

Going ahead to step 5:
51 goes into 61 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1041.0
The remainder is 10 after subtracting 51 from 61.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 51

Going ahead to step 6:
If we divide 109 by 51, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 10412.0
The remainder is 7 after subtracting 102 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 51 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 10412.1
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
If we divide 190 by 51, we get 3 and a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 10412.13
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
When dividing 370 by 51, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 10412.137
The remainder is 13 after subtracting 357 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
If we divide 130 by 51, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 10412.1372
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 10412.13725
If we subtract 255 from 280, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
When dividing 250 by 51, we get 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 10412.137254
Subtracting 204 from 250 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
51 goes into 460 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 10412.1372549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
If we divide 10 by 51, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10412.1372549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 10412.1372549 with a remaining 1e-08.
