We look at the division of 40135097 by 905 
We want to divide 40135097 by 905.

Step 1:
When dividing 4 by 905, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 905

Going ahead to step 2:
905 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 905

Step 3:
905 can be fit into 401 0 times, resulting in a remainder of 401.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 401, we end up with 401.
Take the next digit (3) from the dividend and append it to 401, then repeat: 4013 / 905

Going ahead to step 4:
905 goes into 4013 4 times with a remainder of 393.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 393 after subtracting 3620 from 4013.
Take the next digit (5) from the dividend and append it to 393, then repeat: 3935 / 905

Step 5:
If we divide 3935 by 905, we get 4 and a remainder of 315.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtract 3620 from 3935 to get 315.
Bring next digit (0) of the dividend behind the 315 and repeat the process: 3150 / 905

Moving on to step 6:
When dividing 3150 by 905, we get 3 with a remainder of 435.
Use 3 as the next digit of our solution. 
Result so far: 443.0
Subtracting 2715 from 3150 leaves us with 435.
Fetch the next digit (9) from the dividend, attach it to 435 and continue: 4359 / 905

Step 7:
4359 divided by 905 is 4 with a remainder of 739.
The number 4 becomes the next digit in our result. 
Result so far: 4434.0
Subtract 3620 from 4359 to get 739.
Fetch the next digit (7) from the dividend, attach it to 739 and continue: 7397 / 905

Going ahead to step 8:
905 goes into 7397 8 times with a remainder of 157.
Write down 8 as next digit of the result. 
Result so far: 44348.0
Subtract 7240 from 7397 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 9:
If we divide 1570 by 905, we get 1 and a remainder of 665.
The next digit of our result is 1. 
Result so far: 44348.1
If we subtract 905 from 1570, we get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Let's proceed to step 10:
6650 divided by 905 is 7 with a remainder of 315.
Put 7 as the next digit of the answer. 
Result so far: 44348.17
If we subtract 6335 from 6650, we 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.

Advancing to step 11:
905 goes into 3150 3 times with a remainder of 435.
Put 3 as the next digit of the answer. 
Result so far: 44348.173
Deduct 2715 from 3150 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 12:
If we divide 4350 by 905, we get 4 and a remainder of 730.
Use 4 as the next digit of our solution. 
Result so far: 44348.1734
If we subtract 3620 from 4350, we get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 13:
905 can be fit into 7300 8 times, resulting in a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 44348.17348
Deduct 7240 from 7300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
When dividing 600 by 905, we get 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 44348.17348
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 15:
905 can be fit into 6000 6 times, resulting in a remainder of 570.
Put 6 as the next digit of the answer. 
Result so far: 44348.1734806
If we subtract 5430 from 6000, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 16:
When dividing 5700 by 905, we get 6 with a remainder of 270.
The number 6 becomes the next digit in our result. 
Result so far: 44348.17348066
If we take 5430 away from 5700, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 44348.17348066, with a leftover of 2.7e-07.
