We look at the division of 50880863 by 40 
The aim is to understand the frequency of 40 in 50880863.

Step 1:
When dividing 5 by 40, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 40

Step 2:
When dividing 50 by 40, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 40 from 50 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 40

Advancing to step 3:
40 can be fit into 108 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 28 after subtracting 80 from 108.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 40

Going ahead to step 4:
The number 40 fits into 288 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 127.0
Subtracting 280 from 288 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 40

Moving on to step 5:
If we divide 80 by 40, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 1272.0
Subtracting 80 from 80 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 40

Step 6:
40 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 12720.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 40

Let's proceed to step 7:
40 can be fit into 86 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 127202.0
Subtract 80 from 86 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 40

On to step 8:
If we divide 63 by 40, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 1272021.0
Deduct 40 from 63 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
If we divide 230 by 40, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1272021.5
Subtracting 200 from 230 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 40 is 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 1272021.57
Subtract 280 from 300 to 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.

On to step 11:
200 divided by 40 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1272021.575
If we subtract 200 from 200, 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.

Moving on to step 12:
If we divide 0 by 40, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1272021.575
Subtract 0 from 0 to 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.

Let's proceed to step 13:
When dividing 0 by 40, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1272021.575
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.

After the division, we end up with 1272021.575 and a remainder of 0.0.
