69517957 divided by 818 
The aim is to understand the frequency of 818 in 69517957.

Step 1:
The number 818 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 818

On to step 2:
69 divided by 818 is 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Include the next digit (5) from the dividend after 69, then repeat: 695 / 818

Advancing to step 3:
If we divide 695 by 818, we get 0 and a remainder of 695.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 695 to get 695.
Include the next digit (1) from the dividend after 695, then repeat: 6951 / 818

On to step 4:
818 can be fit into 6951 8 times, resulting in a remainder of 407.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 407 after subtracting 6544 from 6951.
Bring next digit (7) of the dividend behind the 407 and repeat the process: 4077 / 818

Going ahead to step 5:
The number 818 fits into 4077 4 times, leaving a remainder of 805.
The next digit of our result is 4. 
Result so far: 84.0
If we take 3272 away from 4077, we end up with 805.
Include the next digit (9) from the dividend after 805, then repeat: 8059 / 818

Going ahead to step 6:
818 can be fit into 8059 9 times, resulting in a remainder of 697.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
The remainder is 697 after subtracting 7362 from 8059.
Fetch the next digit (5) from the dividend, attach it to 697 and continue: 6975 / 818

Going ahead to step 7:
When dividing 6975 by 818, we get 8 with a remainder of 431.
The number 8 becomes the next digit in our result. 
Result so far: 8498.0
Subtracting 6544 from 6975 leaves us with 431.
Include the next digit (7) from the dividend after 431, then repeat: 4317 / 818

Going ahead to step 8:
818 can be fit into 4317 5 times, resulting in a remainder of 227.
Put 5 as the next digit of the answer. 
Result so far: 84985.0
If we take 4090 away from 4317, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Let's proceed to step 9:
818 can be fit into 2270 2 times, resulting in a remainder of 634.
Use 2 as the next digit of our solution. 
Result so far: 84985.2
Subtracting 1636 from 2270 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Step 10:
818 goes into 6340 7 times with a remainder of 614.
The next digit of our result is 7. 
Result so far: 84985.27
Subtract 5726 from 6340 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Let's proceed to step 11:
If we divide 6140 by 818, we get 7 and a remainder of 414.
The next digit of our result is 7. 
Result so far: 84985.277
Subtract 5726 from 6140 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The final outcome is 84985.277, with a leftover of 0.0414.
