We look at the division of 17788958 by 651 
The aim is to understand the frequency of 651 in 17788958.

Advancing to step 1:
651 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 651

Step 2:
If we divide 17 by 651, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 651

Moving on to step 3:
When dividing 177 by 651, we get 0 with a remainder of 177.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 177 and we're left with 177.
Fetch the next digit (8) from the dividend, attach it to 177 and continue: 1778 / 651

On to step 4:
651 goes into 1778 2 times with a remainder of 476.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1302 from 1778 leaves us with 476.
Include the next digit (8) from the dividend after 476, then repeat: 4768 / 651

Advancing to step 5:
The number 651 fits into 4768 7 times, leaving a remainder of 211.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 4557 from 4768 to get 211.
Include the next digit (9) from the dividend after 211, then repeat: 2119 / 651

Let's proceed to step 6:
2119 divided by 651 is 3 with a remainder of 166.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
Subtracting 1953 from 2119 leaves us with 166.
Fetch the next digit (5) from the dividend, attach it to 166 and continue: 1665 / 651

Moving on to step 7:
When dividing 1665 by 651, we get 2 with a remainder of 363.
The number 2 becomes the next digit in our result. 
Result so far: 2732.0
Deduct 1302 from 1665 and we're left with 363.
Bring next digit (8) of the dividend behind the 363 and repeat the process: 3638 / 651

On to step 8:
3638 divided by 651 is 5 with a remainder of 383.
The next digit of our result is 5. 
Result so far: 27325.0
Subtracting 3255 from 3638 leaves us with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Moving on to step 9:
If we divide 3830 by 651, we get 5 and a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 27325.5
If we take 3255 away from 3830, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Going ahead to step 10:
651 can be fit into 5750 8 times, resulting in a remainder of 542.
Use 8 as the next digit of our solution. 
Result so far: 27325.58
If we subtract 5208 from 5750, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Going ahead to step 11:
When dividing 5420 by 651, we get 8 with a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 27325.588
The remainder is 212 after subtracting 5208 from 5420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 27325.588 with a remainder of 0.0212.
