We're dividing 40136651 by 905 
Our goal is to divide 40136651 by 905.

Going ahead to step 1:
When dividing 4 by 905, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 905

Step 2:
The number 905 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 905

Advancing to step 3:
The number 905 fits into 401 0 times, leaving a remainder of 401.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 401 after subtracting 0 from 401.
Take the next digit (3) from the dividend and append it to 401, then repeat: 4013 / 905

Going ahead to step 4:
If we divide 4013 by 905, we get 4 and a remainder of 393.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3620 from 4013, we get 393.
Include the next digit (6) from the dividend after 393, then repeat: 3936 / 905

Advancing to step 5:
If we divide 3936 by 905, we get 4 and a remainder of 316.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 3620 from 3936, we get 316.
Append the next digit (6) from the dividend to 316 and continue with: 3166 / 905

Let's proceed to step 6:
3166 divided by 905 is 3 with a remainder of 451.
The next digit of our result is 3. 
Result so far: 443.0
If we subtract 2715 from 3166, we get 451.
Include the next digit (5) from the dividend after 451, then repeat: 4515 / 905

Let's proceed to step 7:
4515 divided by 905 is 4 with a remainder of 895.
Record the quotient 4 as the next digit in the result. 
Result so far: 4434.0
The remainder is 895 after subtracting 3620 from 4515.
Grab the next digit (1) from the dividend, add it to 895, then carry on: 8951 / 905

Step 8:
If we divide 8951 by 905, we get 9 and a remainder of 806.
Record the quotient 9 as the next digit in the result. 
Result so far: 44349.0
If we take 8145 away from 8951, we end up with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Step 9:
905 goes into 8060 8 times with a remainder of 820.
The number 8 becomes the next digit in our result. 
Result so far: 44349.8
If we take 7240 away from 8060, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 10:
If we divide 8200 by 905, we get 9 and a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 44349.89
If we take 8145 away from 8200, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 11:
If we divide 550 by 905, we get 0 and a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 44349.89
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 12:
If we divide 5500 by 905, we get 6 and a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 44349.8906
Subtract 5430 from 5500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
When dividing 700 by 905, we get 0 with a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 44349.8906
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 14:
905 can be fit into 7000 7 times, resulting in a remainder of 665.
Put 7 as the next digit of the answer. 
Result so far: 44349.890607
Deduct 6335 from 7000 and we're left with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Advancing to step 15:
6650 divided by 905 is 7 with a remainder of 315.
Put 7 as the next digit of the answer. 
Result so far: 44349.8906077
Subtract 6335 from 6650 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final result is 44349.8906077 with a remainder of 3.15e-06.
