Let's divide 76305387 by 336
The aim is to understand the frequency of 336 in 76305387.

Moving on to step 1:
336 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 336

On to step 2:
336 goes into 76 0 times with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Bring next digit (3) of the dividend behind the 76 and repeat the process: 763 / 336

Advancing to step 3:
336 goes into 763 2 times with a remainder of 91.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 672 from 763 leaves us with 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 336

On to step 4:
910 divided by 336 is 2 with a remainder of 238.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 672 from 910 to get 238.
Bring next digit (5) of the dividend behind the 238 and repeat the process: 2385 / 336

Going ahead to step 5:
336 can be fit into 2385 7 times, resulting in a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 227.0
The remainder is 33 after subtracting 2352 from 2385.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 336

Advancing to step 6:
336 goes into 333 0 times with a remainder of 333.
Record the quotient 0 as the next digit in the result. 
Result so far: 2270.0
If we subtract 0 from 333, we get 333.
Append the next digit (8) from the dividend to 333 and continue with: 3338 / 336

Step 7:
3338 divided by 336 is 9 with a remainder of 314.
Use 9 as the next digit of our solution. 
Result so far: 22709.0
If we take 3024 away from 3338, we end up with 314.
Include the next digit (7) from the dividend after 314, then repeat: 3147 / 336

Going ahead to step 8:
When dividing 3147 by 336, we get 9 with a remainder of 123.
The number 9 becomes the next digit in our result. 
Result so far: 227099.0
The remainder is 123 after subtracting 3024 from 3147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 9:
336 can be fit into 1230 3 times, resulting in a remainder of 222.
Put 3 as the next digit of the answer. 
Result so far: 227099.3
Subtract 1008 from 1230 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 10:
336 can be fit into 2220 6 times, resulting in a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 227099.36
If we take 2016 away from 2220, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 11:
336 can be fit into 2040 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 227099.366
Subtract 2016 from 2040 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 227099.366, with a leftover of 0.0024.
