Let's divide 570541 by 51
The aim is to understand the frequency of 51 in 570541.

Advancing to step 1:
If we divide 5 by 51, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 51

On to step 2:
51 can be fit into 57 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 51 away from 57, we end up with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 51

Advancing to step 3:
51 goes into 60 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 51 from 60, we get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 51

Step 4:
When dividing 95 by 51, we get 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 111.0
Subtract 51 from 95 to get 44.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 51

On to step 5:
When dividing 444 by 51, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 1118.0
Subtracting 408 from 444 leaves us with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 51

Step 6:
When dividing 361 by 51, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 11187.0
Subtract 357 from 361 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 51, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11187.0
Subtracting 0 from 40 leaves us 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.

On to step 8:
If we divide 400 by 51, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 11187.07
If we take 357 away from 400, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
The number 51 fits into 430 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 11187.078
Deduct 408 from 430 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
When dividing 220 by 51, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 11187.0784
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
51 can be fit into 160 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 11187.07843
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
51 goes into 70 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11187.078431
Deduct 51 from 70 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
51 can be fit into 190 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 11187.0784313
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.

On to step 14:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 11187.07843137
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 11187.07843137 and a remainder of 1.3e-08.
