78778617 divided by 236 
The aim is to understand the frequency of 236 in 78778617.

Let's proceed to step 1:
When dividing 7 by 236, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 236

On to step 2:
236 can be fit into 78 0 times, resulting in a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 236

Let's proceed to step 3:
The number 236 fits into 787 3 times, leaving a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 708 from 787 and we're left with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 236

On to step 4:
When dividing 797 by 236, we get 3 with a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtract 708 from 797 to get 89.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 236

Step 5:
If we divide 898 by 236, we get 3 and a remainder of 190.
The next digit of our result is 3. 
Result so far: 333.0
Deduct 708 from 898 and we're left with 190.
Fetch the next digit (6) from the dividend, attach it to 190 and continue: 1906 / 236

Step 6:
If we divide 1906 by 236, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 3338.0
The remainder is 18 after subtracting 1888 from 1906.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 236

Let's proceed to step 7:
The number 236 fits into 181 0 times, leaving a remainder of 181.
Write down 0 as next digit of the result. 
Result so far: 33380.0
The remainder is 181 after subtracting 0 from 181.
Include the next digit (7) from the dividend after 181, then repeat: 1817 / 236

Going ahead to step 8:
1817 divided by 236 is 7 with a remainder of 165.
The next digit of our result is 7. 
Result so far: 333807.0
If we subtract 1652 from 1817, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 9:
236 goes into 1650 6 times with a remainder of 234.
The next digit of our result is 6. 
Result so far: 333807.6
Subtract 1416 from 1650 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 10:
If we divide 2340 by 236, we get 9 and a remainder of 216.
Write down 9 as next digit of the result. 
Result so far: 333807.69
The remainder is 216 after subtracting 2124 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 11:
The number 236 fits into 2160 9 times, leaving a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 333807.699
If we take 2124 away from 2160, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 333807.699, and the remainder is 0.0036.
