496637 divided by 40 
The aim is to understand the frequency of 40 in 496637.

Going ahead to step 1:
The number 40 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 40

Let's proceed to step 2:
If we divide 49 by 40, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 40 from 49 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 40

Let's proceed to step 3:
The number 40 fits into 96 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 80 from 96 to get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 40

Going ahead to step 4:
If we divide 166 by 40, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Deduct 160 from 166 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 40

Going ahead to step 5:
63 divided by 40 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1241.0
Deduct 40 from 63 and we're left with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 40

Going ahead to step 6:
237 divided by 40 is 5 with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 12415.0
If we subtract 200 from 237, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
If we divide 370 by 40, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 12415.9
Deduct 360 from 370 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 40, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 12415.92
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12415.925
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12415.925
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
When dividing 0 by 40, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12415.925
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 12415.925 with a remaining 0.0.
