We're dividing 40570549 by 999 
We're looking to find how many times 999 goes into 40570549.

Going ahead to step 1:
When dividing 4 by 999, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 999

Let's proceed to step 2:
The number 999 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 999

Step 3:
The number 999 fits into 405 0 times, leaving a remainder of 405.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 405, we end up with 405.
Bring next digit (7) of the dividend behind the 405 and repeat the process: 4057 / 999

Going ahead to step 4:
999 goes into 4057 4 times with a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3996 from 4057 to get 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 999

Let's proceed to step 5:
The number 999 fits into 610 0 times, leaving a remainder of 610.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 610 to get 610.
Fetch the next digit (5) from the dividend, attach it to 610 and continue: 6105 / 999

Step 6:
999 can be fit into 6105 6 times, resulting in a remainder of 111.
Use 6 as the next digit of our solution. 
Result so far: 406.0
If we take 5994 away from 6105, we end up with 111.
Include the next digit (4) from the dividend after 111, then repeat: 1114 / 999

Advancing to step 7:
999 can be fit into 1114 1 times, resulting in a remainder of 115.
The next digit of our result is 1. 
Result so far: 4061.0
Subtract 999 from 1114 to get 115.
Fetch the next digit (9) from the dividend, attach it to 115 and continue: 1159 / 999

Going ahead to step 8:
999 goes into 1159 1 times with a remainder of 160.
Use 1 as the next digit of our solution. 
Result so far: 40611.0
Subtracting 999 from 1159 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
999 goes into 1600 1 times with a remainder of 601.
Write down 1 as next digit of the result. 
Result so far: 40611.1
Subtract 999 from 1600 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

On to step 10:
999 goes into 6010 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 40611.16
If we take 5994 away from 6010, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 999 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 40611.16
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
1600 divided by 999 is 1 with a remainder of 601.
Record the quotient 1 as the next digit in the result. 
Result so far: 40611.1601
Subtracting 999 from 1600 leaves us with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Moving on to step 13:
The number 999 fits into 6010 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 40611.16016
Subtract 5994 from 6010 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.

On to step 14:
The number 999 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 40611.16016
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
When dividing 1600 by 999, we get 1 with a remainder of 601.
Put 1 as the next digit of the answer. 
Result so far: 40611.1601601
If we take 999 away from 1600, we end up with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

On to step 16:
If we divide 6010 by 999, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 40611.16016016
Deduct 5994 from 6010 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 40611.16016016, with a leftover of 1.6e-08.
