599419 ÷ 51 
The aim is to understand the frequency of 51 in 599419.

Advancing to step 1:
51 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 51

Moving on to step 2:
When dividing 59 by 51, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 51 away from 59, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 51

Moving on to step 3:
51 goes into 89 1 times with a remainder of 38.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 51 from 89, we get 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 51

Advancing to step 4:
51 goes into 384 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Deduct 357 from 384 and we're left with 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 51

Moving on to step 5:
271 divided by 51 is 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 1175.0
The remainder is 16 after subtracting 255 from 271.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 51

Advancing to step 6:
The number 51 fits into 169 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 11753.0
The remainder is 16 after subtracting 153 from 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
If we divide 160 by 51, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 11753.3
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
51 can be fit into 70 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 11753.31
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.

On to step 9:
When dividing 190 by 51, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 11753.313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
When dividing 370 by 51, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 11753.3137
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.

Moving on to step 11:
51 goes into 130 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 11753.31372
If we take 102 away from 130, we end up 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.

Let's proceed to step 12:
If we divide 280 by 51, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11753.313725
Deduct 255 from 280 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 11753.3137254
If we take 204 away from 250, we end up 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 14:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 11753.31372549
If we subtract 459 from 460, we 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.

The final outcome is 11753.31372549, with a leftover of 1e-09.
