64627251 ÷ 818 
The aim is to understand the frequency of 818 in 64627251.

Going ahead to step 1:
818 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 818

Moving on to step 2:
64 divided by 818 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 818

Let's proceed to step 3:
818 goes into 646 0 times with a remainder of 646.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 646 after subtracting 0 from 646.
Include the next digit (2) from the dividend after 646, then repeat: 6462 / 818

Going ahead to step 4:
6462 divided by 818 is 7 with a remainder of 736.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 5726 away from 6462, we end up with 736.
Bring next digit (7) of the dividend behind the 736 and repeat the process: 7367 / 818

On to step 5:
When dividing 7367 by 818, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 79.0
If we subtract 7362 from 7367, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 818

Step 6:
When dividing 52 by 818, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 790.0
If we take 0 away from 52, we end up with 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 818

Going ahead to step 7:
525 divided by 818 is 0 with a remainder of 525.
Use 0 as the next digit of our solution. 
Result so far: 7900.0
If we subtract 0 from 525, we get 525.
Append the next digit (1) from the dividend to 525 and continue with: 5251 / 818

Let's proceed to step 8:
5251 divided by 818 is 6 with a remainder of 343.
The next digit of our result is 6. 
Result so far: 79006.0
If we subtract 4908 from 5251, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 9:
818 goes into 3430 4 times with a remainder of 158.
Write down 4 as next digit of the result. 
Result so far: 79006.4
Subtracting 3272 from 3430 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 10:
When dividing 1580 by 818, we get 1 with a remainder of 762.
Use 1 as the next digit of our solution. 
Result so far: 79006.41
If we subtract 818 from 1580, we get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

On to step 11:
The number 818 fits into 7620 9 times, leaving a remainder of 258.
Write down 9 as next digit of the result. 
Result so far: 79006.419
Subtracting 7362 from 7620 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 12:
When dividing 2580 by 818, we get 3 with a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 79006.4193
Deduct 2454 from 2580 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 13:
818 goes into 1260 1 times with a remainder of 442.
Use 1 as the next digit of our solution. 
Result so far: 79006.41931
The remainder is 442 after subtracting 818 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 14:
818 goes into 4420 5 times with a remainder of 330.
The number 5 becomes the next digit in our result. 
Result so far: 79006.419315
The remainder is 330 after subtracting 4090 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 15:
3300 divided by 818 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 79006.4193154
Subtracting 3272 from 3300 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 16:
When dividing 280 by 818, we get 0 with a remainder of 280.
The next digit of our result is 0. 
Result so far: 79006.4193154
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 79006.4193154 with a remainder of 2.8e-07.
