We're dividing 581752 by 51 
The aim is to understand the frequency of 51 in 581752.

Advancing to step 1:
51 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 51

Advancing to step 2:
The number 51 fits into 58 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 51 from 58 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 51

Step 3:
51 goes into 71 1 times with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 51 from 71 to get 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 51

Let's proceed to step 4:
51 goes into 207 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 114.0
The remainder is 3 after subtracting 204 from 207.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 51

Let's proceed to step 5:
51 can be fit into 35 0 times, resulting in a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 1140.0
Subtract 0 from 35 to get 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 51

Going ahead to step 6:
If we divide 352 by 51, we get 6 and a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 11406.0
Subtract 306 from 352 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
If we divide 460 by 51, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 11406.9
If we take 459 away from 460, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
The number 51 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 11406.9
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.

Advancing to step 9:
51 goes into 100 1 times with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 11406.901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 11406.9019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
When dividing 310 by 51, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 11406.90196
Subtracting 306 from 310 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
When dividing 40 by 51, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11406.90196
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 11406.9019607
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 14:
51 goes into 430 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 11406.90196078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 11406.90196078 and a remainder of 2.2e-08.
