We look at the division of 40493818 by 849 
We want to divide 40493818 by 849.

Going ahead to step 1:
4 divided by 849 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 849

Step 2:
849 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 849

On to step 3:
If we divide 404 by 849, we get 0 and a remainder of 404.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 404 leaves us with 404.
Fetch the next digit (9) from the dividend, attach it to 404 and continue: 4049 / 849

On to step 4:
When dividing 4049 by 849, we get 4 with a remainder of 653.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 3396 from 4049 leaves us with 653.
Append the next digit (3) from the dividend to 653 and continue with: 6533 / 849

Step 5:
849 goes into 6533 7 times with a remainder of 590.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 5943 from 6533 leaves us with 590.
Include the next digit (8) from the dividend after 590, then repeat: 5908 / 849

On to step 6:
849 can be fit into 5908 6 times, resulting in a remainder of 814.
The number 6 becomes the next digit in our result. 
Result so far: 476.0
Deduct 5094 from 5908 and we're left with 814.
Bring next digit (1) of the dividend behind the 814 and repeat the process: 8141 / 849

On to step 7:
8141 divided by 849 is 9 with a remainder of 500.
The next digit of our result is 9. 
Result so far: 4769.0
Subtract 7641 from 8141 to get 500.
Include the next digit (8) from the dividend after 500, then repeat: 5008 / 849

Let's proceed to step 8:
849 goes into 5008 5 times with a remainder of 763.
Put 5 as the next digit of the answer. 
Result so far: 47695.0
The remainder is 763 after subtracting 4245 from 5008.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Let's proceed to step 9:
849 can be fit into 7630 8 times, resulting in a remainder of 838.
Use 8 as the next digit of our solution. 
Result so far: 47695.8
If we subtract 6792 from 7630, we get 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Going ahead to step 10:
If we divide 8380 by 849, we get 9 and a remainder of 739.
Record the quotient 9 as the next digit in the result. 
Result so far: 47695.89
If we take 7641 away from 8380, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Advancing to step 11:
The number 849 fits into 7390 8 times, leaving a remainder of 598.
Record the quotient 8 as the next digit in the result. 
Result so far: 47695.898
Deduct 6792 from 7390 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 12:
849 can be fit into 5980 7 times, resulting in a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 47695.8987
If we take 5943 away from 5980, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
849 goes into 370 0 times with a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 47695.8987
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 14:
If we divide 3700 by 849, we get 4 and a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 47695.898704
If we subtract 3396 from 3700, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 15:
849 goes into 3040 3 times with a remainder of 493.
Record the quotient 3 as the next digit in the result. 
Result so far: 47695.8987043
Subtracting 2547 from 3040 leaves us with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

On to step 16:
The number 849 fits into 4930 5 times, leaving a remainder of 685.
The next digit of our result is 5. 
Result so far: 47695.89870435
If we subtract 4245 from 4930, we get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

After the division, we end up with 47695.89870435 and a remainder of 6.85e-07.
