40666919 ÷ 207 
We want to figure out the number of times 40666919 can be divided by 207.

Step 1:
The number 207 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 207

Moving on to step 2:
If we divide 40 by 207, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 207

Moving on to step 3:
If we divide 406 by 207, we get 1 and a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 207 from 406 to get 199.
Take the next digit (6) from the dividend and append it to 199, then repeat: 1996 / 207

Going ahead to step 4:
207 can be fit into 1996 9 times, resulting in a remainder of 133.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 133 after subtracting 1863 from 1996.
Grab the next digit (6) from the dividend, add it to 133, then carry on: 1336 / 207

Advancing to step 5:
If we divide 1336 by 207, we get 6 and a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 196.0
If we subtract 1242 from 1336, we get 94.
Include the next digit (9) from the dividend after 94, then repeat: 949 / 207

On to step 6:
949 divided by 207 is 4 with a remainder of 121.
Write down 4 as next digit of the result. 
Result so far: 1964.0
Subtract 828 from 949 to get 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 207

Moving on to step 7:
207 can be fit into 1211 5 times, resulting in a remainder of 176.
Write down 5 as next digit of the result. 
Result so far: 19645.0
Subtracting 1035 from 1211 leaves us with 176.
Fetch the next digit (9) from the dividend, attach it to 176 and continue: 1769 / 207

Going ahead to step 8:
207 goes into 1769 8 times with a remainder of 113.
Use 8 as the next digit of our solution. 
Result so far: 196458.0
Subtracting 1656 from 1769 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 9:
207 goes into 1130 5 times with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 196458.5
Deduct 1035 from 1130 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 10:
207 can be fit into 950 4 times, resulting in a remainder of 122.
The next digit of our result is 4. 
Result so far: 196458.54
Deduct 828 from 950 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 11:
207 goes into 1220 5 times with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 196458.545
Subtracting 1035 from 1220 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 12:
1850 divided by 207 is 8 with a remainder of 194.
Record the quotient 8 as the next digit in the result. 
Result so far: 196458.5458
Subtract 1656 from 1850 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 13:
The number 207 fits into 1940 9 times, leaving a remainder of 77.
The next digit of our result is 9. 
Result so far: 196458.54589
Subtract 1863 from 1940 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 14:
207 can be fit into 770 3 times, resulting in a remainder of 149.
The number 3 becomes the next digit in our result. 
Result so far: 196458.545893
If we take 621 away from 770, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 15:
1490 divided by 207 is 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 196458.5458937
Deduct 1449 from 1490 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 16:
The number 207 fits into 410 1 times, leaving a remainder of 203.
Write down 1 as next digit of the result. 
Result so far: 196458.54589371
If we subtract 207 from 410, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

The final result is 196458.54589371 with a remainder of 2.03e-07.
