337284 divided by 51 
The aim is to understand the frequency of 51 in 337284.

Step 1:
The number 51 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 51

Going ahead to step 2:
If we divide 33 by 51, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 51

On to step 3:
When dividing 337 by 51, we get 6 with a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 31 after subtracting 306 from 337.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 51

Moving on to step 4:
51 can be fit into 312 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we subtract 306 from 312, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 51

Advancing to step 5:
51 goes into 68 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 661.0
If we subtract 51 from 68, we get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 51

Going ahead to step 6:
When dividing 174 by 51, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 6613.0
If we subtract 153 from 174, 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.

On to step 7:
When dividing 210 by 51, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 6613.4
Subtracting 204 from 210 leaves us with 6.
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 8:
When dividing 60 by 51, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 6613.41
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.

Going ahead to step 9:
51 goes into 90 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 6613.411
Subtract 51 from 90 to get 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 6613.411, and the remainder is 0.0039.
