40647684 divided by 40 
The aim is to understand the frequency of 40 in 40647684.

Let's proceed to step 1:
If we divide 4 by 40, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 40

Moving on to step 2:
40 divided by 40 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 40 away from 40, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 40

Step 3:
40 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 40

Step 4:
64 divided by 40 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 101.0
The remainder is 24 after subtracting 40 from 64.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 40

On to step 5:
When dividing 247 by 40, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 1016.0
Subtract 240 from 247 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 40

Advancing to step 6:
If we divide 76 by 40, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 10161.0
Subtract 40 from 76 to get 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 40

On to step 7:
40 goes into 368 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 101619.0
Subtracting 360 from 368 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 40

Let's proceed to step 8:
If we divide 84 by 40, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1016192.0
Subtract 80 from 84 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 goes into 40 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1016192.1
If we subtract 40 from 40, 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.

On to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1016192.1
Subtracting 0 from 0 leaves us with 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:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1016192.1
If we take 0 away from 0, we end up with 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 1016192.1 with a remaining 0.0.
