Let's divide 40520491 by 555
Our goal is to divide 40520491 by 555.

Going ahead to step 1:
If we divide 4 by 555, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 555

On to step 2:
When dividing 40 by 555, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 555

Going ahead to step 3:
555 goes into 405 0 times with a remainder of 405.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 405 and we're left with 405.
Fetch the next digit (2) from the dividend, attach it to 405 and continue: 4052 / 555

Going ahead to step 4:
555 can be fit into 4052 7 times, resulting in a remainder of 167.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 3885 from 4052 leaves us with 167.
Grab the next digit (0) from the dividend, add it to 167, then carry on: 1670 / 555

Let's proceed to step 5:
555 can be fit into 1670 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 73.0
Deduct 1665 from 1670 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 555

Let's proceed to step 6:
555 can be fit into 54 0 times, resulting in a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 730.0
Subtracting 0 from 54 leaves us with 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 555

Let's proceed to step 7:
If we divide 549 by 555, we get 0 and a remainder of 549.
Use 0 as the next digit of our solution. 
Result so far: 7300.0
Deduct 0 from 549 and we're left with 549.
Append the next digit (1) from the dividend to 549 and continue with: 5491 / 555

On to step 8:
If we divide 5491 by 555, we get 9 and a remainder of 496.
The next digit of our result is 9. 
Result so far: 73009.0
Subtract 4995 from 5491 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 9:
555 goes into 4960 8 times with a remainder of 520.
The next digit of our result is 8. 
Result so far: 73009.8
Deduct 4440 from 4960 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 10:
When dividing 5200 by 555, we get 9 with a remainder of 205.
Record the quotient 9 as the next digit in the result. 
Result so far: 73009.89
Subtract 4995 from 5200 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 11:
If we divide 2050 by 555, we get 3 and a remainder of 385.
Put 3 as the next digit of the answer. 
Result so far: 73009.893
Deduct 1665 from 2050 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 12:
If we divide 3850 by 555, we get 6 and a remainder of 520.
The next digit of our result is 6. 
Result so far: 73009.8936
If we take 3330 away from 3850, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 13:
555 can be fit into 5200 9 times, resulting in a remainder of 205.
The next digit of our result is 9. 
Result so far: 73009.89369
Subtract 4995 from 5200 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 14:
2050 divided by 555 is 3 with a remainder of 385.
Put 3 as the next digit of the answer. 
Result so far: 73009.893693
If we subtract 1665 from 2050, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 15:
3850 divided by 555 is 6 with a remainder of 520.
Use 6 as the next digit of our solution. 
Result so far: 73009.8936936
If we take 3330 away from 3850, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 16:
When dividing 5200 by 555, we get 9 with a remainder of 205.
The number 9 becomes the next digit in our result. 
Result so far: 73009.89369369
Subtract 4995 from 5200 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Our division results in 73009.89369369 with a remaining 2.05e-07.
