We're dividing 78813338 by 636 
The aim is to understand the frequency of 636 in 78813338.

Going ahead to step 1:
636 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 636

Going ahead to step 2:
636 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 636

Step 3:
If we divide 788 by 636, we get 1 and a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 152 after subtracting 636 from 788.
Bring next digit (1) of the dividend behind the 152 and repeat the process: 1521 / 636

On to step 4:
636 goes into 1521 2 times with a remainder of 249.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 249 after subtracting 1272 from 1521.
Grab the next digit (3) from the dividend, add it to 249, then carry on: 2493 / 636

Advancing to step 5:
636 goes into 2493 3 times with a remainder of 585.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Subtracting 1908 from 2493 leaves us with 585.
Fetch the next digit (3) from the dividend, attach it to 585 and continue: 5853 / 636

Step 6:
636 can be fit into 5853 9 times, resulting in a remainder of 129.
The next digit of our result is 9. 
Result so far: 1239.0
The remainder is 129 after subtracting 5724 from 5853.
Include the next digit (3) from the dividend after 129, then repeat: 1293 / 636

Going ahead to step 7:
636 goes into 1293 2 times with a remainder of 21.
The next digit of our result is 2. 
Result so far: 12392.0
If we subtract 1272 from 1293, we get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 636

Step 8:
The number 636 fits into 218 0 times, leaving a remainder of 218.
The next digit of our result is 0. 
Result so far: 123920.0
The remainder is 218 after subtracting 0 from 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 9:
When dividing 2180 by 636, we get 3 with a remainder of 272.
Use 3 as the next digit of our solution. 
Result so far: 123920.3
If we subtract 1908 from 2180, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 10:
The number 636 fits into 2720 4 times, leaving a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 123920.34
If we subtract 2544 from 2720, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 11:
The number 636 fits into 1760 2 times, leaving a remainder of 488.
Write down 2 as next digit of the result. 
Result so far: 123920.342
Subtract 1272 from 1760 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 12:
If we divide 4880 by 636, we get 7 and a remainder of 428.
Record the quotient 7 as the next digit in the result. 
Result so far: 123920.3427
Deduct 4452 from 4880 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 13:
The number 636 fits into 4280 6 times, leaving a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 123920.34276
The remainder is 464 after subtracting 3816 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 14:
The number 636 fits into 4640 7 times, leaving a remainder of 188.
Use 7 as the next digit of our solution. 
Result so far: 123920.342767
If we take 4452 away from 4640, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 15:
If we divide 1880 by 636, we get 2 and a remainder of 608.
The number 2 becomes the next digit in our result. 
Result so far: 123920.3427672
The remainder is 608 after subtracting 1272 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 16:
When dividing 6080 by 636, we get 9 with a remainder of 356.
The number 9 becomes the next digit in our result. 
Result so far: 123920.34276729
Subtract 5724 from 6080 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Our division results in 123920.34276729 with a remaining 3.56e-07.
