We look at the division of 40017989 by 888 
We want to figure out the number of times 40017989 can be divided by 888.

Step 1:
888 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 888

Moving on to step 2:
40 divided by 888 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 888

Advancing to step 3:
400 divided by 888 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 400, we end up with 400.
Bring next digit (1) of the dividend behind the 400 and repeat the process: 4001 / 888

Moving on to step 4:
888 goes into 4001 4 times with a remainder of 449.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3552 away from 4001, we end up with 449.
Append the next digit (7) from the dividend to 449 and continue with: 4497 / 888

Step 5:
The number 888 fits into 4497 5 times, leaving a remainder of 57.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
The remainder is 57 after subtracting 4440 from 4497.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 888

On to step 6:
888 goes into 579 0 times with a remainder of 579.
The next digit of our result is 0. 
Result so far: 450.0
Subtract 0 from 579 to get 579.
Bring next digit (8) of the dividend behind the 579 and repeat the process: 5798 / 888

On to step 7:
If we divide 5798 by 888, we get 6 and a remainder of 470.
Record the quotient 6 as the next digit in the result. 
Result so far: 4506.0
Subtracting 5328 from 5798 leaves us with 470.
Take the next digit (9) from the dividend and append it to 470, then repeat: 4709 / 888

Step 8:
888 goes into 4709 5 times with a remainder of 269.
Use 5 as the next digit of our solution. 
Result so far: 45065.0
Subtracting 4440 from 4709 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 9:
888 goes into 2690 3 times with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 45065.3
If we subtract 2664 from 2690, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
888 goes into 260 0 times with a remainder of 260.
The next digit of our result is 0. 
Result so far: 45065.3
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 11:
If we divide 2600 by 888, we get 2 and a remainder of 824.
Record the quotient 2 as the next digit in the result. 
Result so far: 45065.302
If we take 1776 away from 2600, we end up with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Going ahead to step 12:
When dividing 8240 by 888, we get 9 with a remainder of 248.
Use 9 as the next digit of our solution. 
Result so far: 45065.3029
Deduct 7992 from 8240 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 13:
888 can be fit into 2480 2 times, resulting in a remainder of 704.
Put 2 as the next digit of the answer. 
Result so far: 45065.30292
Subtract 1776 from 2480 to get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Going ahead to step 14:
7040 divided by 888 is 7 with a remainder of 824.
Use 7 as the next digit of our solution. 
Result so far: 45065.302927
Subtract 6216 from 7040 to get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Let's proceed to step 15:
8240 divided by 888 is 9 with a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 45065.3029279
If we take 7992 away from 8240, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 16:
The number 888 fits into 2480 2 times, leaving a remainder of 704.
The next digit of our result is 2. 
Result so far: 45065.30292792
Deduct 1776 from 2480 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

After the division, we end up with 45065.30292792 and a remainder of 7.04e-07.
