78505358 divided by 336 
The aim is to understand the frequency of 336 in 78505358.

Advancing to step 1:
336 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 336

On to step 2:
336 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 336

Going ahead to step 3:
When dividing 785 by 336, we get 2 with a remainder of 113.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 672 from 785 leaves us with 113.
Grab the next digit (0) from the dividend, add it to 113, then carry on: 1130 / 336

Moving on to step 4:
If we divide 1130 by 336, we get 3 and a remainder of 122.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 1008 from 1130 and we're left with 122.
Grab the next digit (5) from the dividend, add it to 122, then carry on: 1225 / 336

Let's proceed to step 5:
When dividing 1225 by 336, we get 3 with a remainder of 217.
The number 3 becomes the next digit in our result. 
Result so far: 233.0
If we take 1008 away from 1225, we end up with 217.
Take the next digit (3) from the dividend and append it to 217, then repeat: 2173 / 336

Advancing to step 6:
When dividing 2173 by 336, we get 6 with a remainder of 157.
Use 6 as the next digit of our solution. 
Result so far: 2336.0
If we take 2016 away from 2173, we end up with 157.
Include the next digit (5) from the dividend after 157, then repeat: 1575 / 336

Going ahead to step 7:
1575 divided by 336 is 4 with a remainder of 231.
The number 4 becomes the next digit in our result. 
Result so far: 23364.0
Subtracting 1344 from 1575 leaves us with 231.
Bring next digit (8) of the dividend behind the 231 and repeat the process: 2318 / 336

Step 8:
If we divide 2318 by 336, we get 6 and a remainder of 302.
The number 6 becomes the next digit in our result. 
Result so far: 233646.0
Subtracting 2016 from 2318 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 9:
336 goes into 3020 8 times with a remainder of 332.
The number 8 becomes the next digit in our result. 
Result so far: 233646.8
If we subtract 2688 from 3020, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 10:
336 goes into 3320 9 times with a remainder of 296.
The next digit of our result is 9. 
Result so far: 233646.89
If we subtract 3024 from 3320, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 11:
The number 336 fits into 2960 8 times, leaving a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 233646.898
The remainder is 272 after subtracting 2688 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 12:
2720 divided by 336 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 233646.8988
Deduct 2688 from 2720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 233646.8988 and a remainder of 0.00032.
