40181145 ÷ 609 
We want to figure out the number of times 40181145 can be divided by 609.

On to step 1:
If we divide 4 by 609, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 609

On to step 2:
609 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 609

Let's proceed to step 3:
If we divide 401 by 609, we get 0 and a remainder of 401.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 401 after subtracting 0 from 401.
Bring next digit (8) of the dividend behind the 401 and repeat the process: 4018 / 609

On to step 4:
609 can be fit into 4018 6 times, resulting in a remainder of 364.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 3654 from 4018, we get 364.
Append the next digit (1) from the dividend to 364 and continue with: 3641 / 609

Advancing to step 5:
609 goes into 3641 5 times with a remainder of 596.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
If we subtract 3045 from 3641, we get 596.
Bring next digit (1) of the dividend behind the 596 and repeat the process: 5961 / 609

Moving on to step 6:
When dividing 5961 by 609, we get 9 with a remainder of 480.
The next digit of our result is 9. 
Result so far: 659.0
If we take 5481 away from 5961, we end up with 480.
Fetch the next digit (4) from the dividend, attach it to 480 and continue: 4804 / 609

Moving on to step 7:
609 goes into 4804 7 times with a remainder of 541.
Write down 7 as next digit of the result. 
Result so far: 6597.0
Subtracting 4263 from 4804 leaves us with 541.
Append the next digit (5) from the dividend to 541 and continue with: 5415 / 609

Step 8:
The number 609 fits into 5415 8 times, leaving a remainder of 543.
The number 8 becomes the next digit in our result. 
Result so far: 65978.0
If we subtract 4872 from 5415, we get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 9:
5430 divided by 609 is 8 with a remainder of 558.
Record the quotient 8 as the next digit in the result. 
Result so far: 65978.8
Subtract 4872 from 5430 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Advancing to step 10:
When dividing 5580 by 609, we get 9 with a remainder of 99.
The next digit of our result is 9. 
Result so far: 65978.89
Subtract 5481 from 5580 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 11:
609 can be fit into 990 1 times, resulting in a remainder of 381.
Write down 1 as next digit of the result. 
Result so far: 65978.891
Subtract 609 from 990 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 12:
609 can be fit into 3810 6 times, resulting in a remainder of 156.
Record the quotient 6 as the next digit in the result. 
Result so far: 65978.8916
Subtract 3654 from 3810 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 13:
609 can be fit into 1560 2 times, resulting in a remainder of 342.
Use 2 as the next digit of our solution. 
Result so far: 65978.89162
If we take 1218 away from 1560, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 14:
If we divide 3420 by 609, we get 5 and a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 65978.891625
Subtract 3045 from 3420 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 15:
When dividing 3750 by 609, we get 6 with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 65978.8916256
The remainder is 96 after subtracting 3654 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 16:
609 can be fit into 960 1 times, resulting in a remainder of 351.
Put 1 as the next digit of the answer. 
Result so far: 65978.89162561
If we subtract 609 from 960, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Our division results in 65978.89162561 with a remaining 3.51e-07.
