We divide 672197 by 51
The aim is to understand the frequency of 51 in 672197.

Going ahead to step 1:
The number 51 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 51

Let's proceed to step 2:
When dividing 67 by 51, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 16 after subtracting 51 from 67.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 51

Going ahead to step 3:
When dividing 162 by 51, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 153 from 162 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 51

Going ahead to step 4:
If we divide 91 by 51, we get 1 and a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Subtracting 51 from 91 leaves us with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 51

Step 5:
If we divide 409 by 51, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 1318.0
Subtracting 408 from 409 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 51

Going ahead to step 6:
When dividing 17 by 51, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 13180.0
The remainder is 17 after subtracting 0 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 51 fits into 170 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 13180.3
If we take 153 away from 170, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
The number 51 fits into 170 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 13180.33
Deduct 153 from 170 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 13180.33, with a leftover of 0.017.
