419616 divided by 40 
The aim is to understand the frequency of 40 in 419616.

Let's proceed to step 1:
When dividing 4 by 40, we get 0 with 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.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 40

Step 2:
40 can be fit into 41 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 40 from 41, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 40

Step 3:
When dividing 19 by 40, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 19 and we're left with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 40

Advancing to step 4:
If we divide 196 by 40, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we take 160 away from 196, we end up with 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 40

Let's proceed to step 5:
40 goes into 361 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1049.0
If we subtract 360 from 361, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 40

Advancing to step 6:
The number 40 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 10490.0
Subtract 0 from 16 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
160 divided by 40 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 10490.4
Subtracting 160 from 160 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 8:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10490.4
Deduct 0 from 0 and we're left 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.

Moving on to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10490.4
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.

The quotient of the division is 10490.4, and the remainder is 0.0.
