We look at the division of 40151839 by 949 
We want to divide 40151839 by 949.

Going ahead to step 1:
949 goes into 4 0 times 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.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 949

Let's proceed to step 2:
949 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 949

Let's proceed to step 3:
949 goes into 401 0 times with a remainder of 401.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 401 after subtracting 0 from 401.
Grab the next digit (5) from the dividend, add it to 401, then carry on: 4015 / 949

Let's proceed to step 4:
When dividing 4015 by 949, we get 4 with a remainder of 219.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3796 from 4015 leaves us with 219.
Fetch the next digit (1) from the dividend, attach it to 219 and continue: 2191 / 949

Step 5:
The number 949 fits into 2191 2 times, leaving a remainder of 293.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 1898 from 2191, we get 293.
Take the next digit (8) from the dividend and append it to 293, then repeat: 2938 / 949

On to step 6:
The number 949 fits into 2938 3 times, leaving a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 423.0
Subtract 2847 from 2938 to get 91.
Take the next digit (3) from the dividend and append it to 91, then repeat: 913 / 949

On to step 7:
If we divide 913 by 949, we get 0 and a remainder of 913.
The number 0 becomes the next digit in our result. 
Result so far: 4230.0
If we take 0 away from 913, we end up with 913.
Include the next digit (9) from the dividend after 913, then repeat: 9139 / 949

Step 8:
When dividing 9139 by 949, we get 9 with a remainder of 598.
Use 9 as the next digit of our solution. 
Result so far: 42309.0
If we subtract 8541 from 9139, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 9:
The number 949 fits into 5980 6 times, leaving a remainder of 286.
The number 6 becomes the next digit in our result. 
Result so far: 42309.6
Deduct 5694 from 5980 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 10:
The number 949 fits into 2860 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 42309.63
If we subtract 2847 from 2860, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
949 can be fit into 130 0 times, resulting in a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 42309.63
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 12:
949 can be fit into 1300 1 times, resulting in a remainder of 351.
Put 1 as the next digit of the answer. 
Result so far: 42309.6301
Subtracting 949 from 1300 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 13:
The number 949 fits into 3510 3 times, leaving a remainder of 663.
Put 3 as the next digit of the answer. 
Result so far: 42309.63013
Deduct 2847 from 3510 and we're left with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Advancing to step 14:
When dividing 6630 by 949, we get 6 with a remainder of 936.
The number 6 becomes the next digit in our result. 
Result so far: 42309.630136
Deduct 5694 from 6630 and we're left with 936.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9360, and continue the process.

On to step 15:
If we divide 9360 by 949, we get 9 and a remainder of 819.
Use 9 as the next digit of our solution. 
Result so far: 42309.6301369
The remainder is 819 after subtracting 8541 from 9360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

Step 16:
949 goes into 8190 8 times with a remainder of 598.
Use 8 as the next digit of our solution. 
Result so far: 42309.63013698
Deduct 7592 from 8190 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.

The final result is 42309.63013698 with a remainder of 5.98e-07.
