We divide 212517 by 51
The aim is to understand the frequency of 51 in 212517.

Step 1:
2 divided by 51 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 51

Advancing to step 2:
51 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 51

Let's proceed to step 3:
51 goes into 212 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 204 from 212, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 51

Moving on to step 4:
When dividing 85 by 51, we get 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtract 51 from 85 to get 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 51

Advancing to step 5:
341 divided by 51 is 6 with a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 416.0
If we subtract 306 from 341, we get 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 51

Advancing to step 6:
51 can be fit into 357 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 4167.0
Deduct 357 from 357 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
When dividing 0 by 51, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4167.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 51 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4167.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4167.0, with a leftover of 0.0.
