40909473 ÷ 636 
The aim is to understand the frequency of 636 in 40909473.

On to step 1:
636 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 636

Going ahead to step 2:
The number 636 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 636

Advancing to step 3:
636 can be fit into 409 0 times, resulting in a remainder of 409.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 409, we end up with 409.
Grab the next digit (0) from the dividend, add it to 409, then carry on: 4090 / 636

Advancing to step 4:
The number 636 fits into 4090 6 times, leaving a remainder of 274.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 3816 from 4090, we get 274.
Append the next digit (9) from the dividend to 274 and continue with: 2749 / 636

On to step 5:
If we divide 2749 by 636, we get 4 and a remainder of 205.
Write down 4 as next digit of the result. 
Result so far: 64.0
The remainder is 205 after subtracting 2544 from 2749.
Grab the next digit (4) from the dividend, add it to 205, then carry on: 2054 / 636

On to step 6:
636 goes into 2054 3 times with a remainder of 146.
Use 3 as the next digit of our solution. 
Result so far: 643.0
Subtract 1908 from 2054 to get 146.
Grab the next digit (7) from the dividend, add it to 146, then carry on: 1467 / 636

Advancing to step 7:
The number 636 fits into 1467 2 times, leaving a remainder of 195.
Use 2 as the next digit of our solution. 
Result so far: 6432.0
Subtract 1272 from 1467 to get 195.
Take the next digit (3) from the dividend and append it to 195, then repeat: 1953 / 636

Let's proceed to step 8:
636 can be fit into 1953 3 times, resulting in a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 64323.0
If we subtract 1908 from 1953, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
636 goes into 450 0 times with a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 64323.0
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
If we divide 4500 by 636, we get 7 and a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 64323.07
If we take 4452 away from 4500, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
The number 636 fits into 480 0 times, leaving a remainder of 480.
The next digit of our result is 0. 
Result so far: 64323.07
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 12:
4800 divided by 636 is 7 with a remainder of 348.
Record the quotient 7 as the next digit in the result. 
Result so far: 64323.0707
If we take 4452 away from 4800, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 13:
3480 divided by 636 is 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 64323.07075
If we subtract 3180 from 3480, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 14:
636 goes into 3000 4 times with a remainder of 456.
Record the quotient 4 as the next digit in the result. 
Result so far: 64323.070754
Subtracting 2544 from 3000 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 15:
4560 divided by 636 is 7 with a remainder of 108.
Write down 7 as next digit of the result. 
Result so far: 64323.0707547
Deduct 4452 from 4560 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 16:
636 goes into 1080 1 times with a remainder of 444.
Put 1 as the next digit of the answer. 
Result so far: 64323.07075471
Deduct 636 from 1080 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Our division results in 64323.07075471 with a remaining 4.44e-07.
