887145 ÷ 40 
The aim is to understand the frequency of 40 in 887145.

Moving on to step 1:
The number 40 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 40

Let's proceed to step 2:
40 goes into 88 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 80 from 88, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 40

Let's proceed to step 3:
40 can be fit into 87 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 80 from 87, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 40

Step 4:
40 can be fit into 71 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 221.0
Deduct 40 from 71 and we're left with 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 40

Advancing to step 5:
40 goes into 314 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 2217.0
If we subtract 280 from 314, we get 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 40

Going ahead to step 6:
If we divide 345 by 40, we get 8 and a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 22178.0
Subtracting 320 from 345 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
40 goes into 250 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 22178.6
If we subtract 240 from 250, we get 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.
Use 2 as the next digit of our solution. 
Result so far: 22178.62
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 40, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 22178.625
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.

Step 10:
40 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22178.625
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.

On to step 11:
40 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22178.625
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.

After the division, we end up with 22178.625 and a remainder of 0.0.
