78805438 ÷ 818 
The aim is to understand the frequency of 818 in 78805438.

Let's proceed to step 1:
818 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 818

Going ahead to step 2:
78 divided by 818 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 818

On to step 3:
818 goes into 788 0 times with a remainder of 788.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 788 after subtracting 0 from 788.
Append the next digit (0) from the dividend to 788 and continue with: 7880 / 818

Advancing to step 4:
7880 divided by 818 is 9 with a remainder of 518.
The next digit of our result is 9. 
Result so far: 9.0
If we take 7362 away from 7880, we end up with 518.
Bring next digit (5) of the dividend behind the 518 and repeat the process: 5185 / 818

Going ahead to step 5:
818 can be fit into 5185 6 times, resulting in a remainder of 277.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 4908 from 5185, we get 277.
Grab the next digit (4) from the dividend, add it to 277, then carry on: 2774 / 818

Step 6:
When dividing 2774 by 818, we get 3 with a remainder of 320.
Put 3 as the next digit of the answer. 
Result so far: 963.0
Deduct 2454 from 2774 and we're left with 320.
Bring next digit (3) of the dividend behind the 320 and repeat the process: 3203 / 818

Step 7:
818 goes into 3203 3 times with a remainder of 749.
Write down 3 as next digit of the result. 
Result so far: 9633.0
The remainder is 749 after subtracting 2454 from 3203.
Include the next digit (8) from the dividend after 749, then repeat: 7498 / 818

Step 8:
When dividing 7498 by 818, we get 9 with a remainder of 136.
The number 9 becomes the next digit in our result. 
Result so far: 96339.0
Deduct 7362 from 7498 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 9:
The number 818 fits into 1360 1 times, leaving a remainder of 542.
Record the quotient 1 as the next digit in the result. 
Result so far: 96339.1
The remainder is 542 after subtracting 818 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Advancing to step 10:
818 goes into 5420 6 times with a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 96339.16
Subtract 4908 from 5420 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 11:
818 can be fit into 5120 6 times, resulting in a remainder of 212.
Put 6 as the next digit of the answer. 
Result so far: 96339.166
The remainder is 212 after subtracting 4908 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

In conclusion, the division gives 96339.166 with a balance of 0.0212.
