We divide 290085 by 51
The aim is to understand the frequency of 51 in 290085.

Let's proceed to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 51

On to step 2:
51 can be fit into 29 0 times, resulting in a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 51

Step 3:
When dividing 290 by 51, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 35 after subtracting 255 from 290.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 51

On to step 4:
350 divided by 51 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we take 306 away from 350, we end up with 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 51

Going ahead to step 5:
If we divide 448 by 51, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 568.0
If we take 408 away from 448, we end up with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 51

Let's proceed to step 6:
405 divided by 51 is 7 with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 5687.0
Deduct 357 from 405 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
51 goes into 480 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 5687.9
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
If we divide 210 by 51, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 5687.94
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
If we divide 60 by 51, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 5687.941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 5687.9411
If we take 51 away from 90, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 5687.9411, and the remainder is 0.00039.
