We look at the division of 40085605 by 906 
We want to divide 40085605 by 906.

Advancing to step 1:
If we divide 4 by 906, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 906

Going ahead to step 2:
906 goes into 40 0 times with 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.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 906

Advancing to step 3:
The number 906 fits into 400 0 times, leaving a remainder of 400.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 400 and we're left with 400.
Fetch the next digit (8) from the dividend, attach it to 400 and continue: 4008 / 906

Advancing to step 4:
The number 906 fits into 4008 4 times, leaving a remainder of 384.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3624 away from 4008, we end up with 384.
Append the next digit (5) from the dividend to 384 and continue with: 3845 / 906

Step 5:
The number 906 fits into 3845 4 times, leaving a remainder of 221.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we take 3624 away from 3845, we end up with 221.
Bring next digit (6) of the dividend behind the 221 and repeat the process: 2216 / 906

Let's proceed to step 6:
The number 906 fits into 2216 2 times, leaving a remainder of 404.
Record the quotient 2 as the next digit in the result. 
Result so far: 442.0
Deduct 1812 from 2216 and we're left with 404.
Take the next digit (0) from the dividend and append it to 404, then repeat: 4040 / 906

Advancing to step 7:
The number 906 fits into 4040 4 times, leaving a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 4424.0
The remainder is 416 after subtracting 3624 from 4040.
Include the next digit (5) from the dividend after 416, then repeat: 4165 / 906

Going ahead to step 8:
4165 divided by 906 is 4 with a remainder of 541.
The number 4 becomes the next digit in our result. 
Result so far: 44244.0
Subtract 3624 from 4165 to get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 9:
If we divide 5410 by 906, we get 5 and a remainder of 880.
Write down 5 as next digit of the result. 
Result so far: 44244.5
If we subtract 4530 from 5410, we get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

On to step 10:
8800 divided by 906 is 9 with a remainder of 646.
Record the quotient 9 as the next digit in the result. 
Result so far: 44244.59
Subtracting 8154 from 8800 leaves us with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 11:
When dividing 6460 by 906, we get 7 with a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 44244.597
The remainder is 118 after subtracting 6342 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 12:
906 goes into 1180 1 times with a remainder of 274.
Use 1 as the next digit of our solution. 
Result so far: 44244.5971
Subtract 906 from 1180 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 13:
The number 906 fits into 2740 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 44244.59713
If we take 2718 away from 2740, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
If we divide 220 by 906, we get 0 and a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 44244.59713
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 15:
906 can be fit into 2200 2 times, resulting in a remainder of 388.
The next digit of our result is 2. 
Result so far: 44244.5971302
Deduct 1812 from 2200 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 16:
906 goes into 3880 4 times with a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 44244.59713024
The remainder is 256 after subtracting 3624 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final result is 44244.59713024 with a remainder of 2.56e-07.
