We're dividing 4057909 by 519 
We're looking to find how many times 519 goes into 4057909.

Step 1:
The number 519 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 519

Advancing to step 2:
If we divide 40 by 519, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 519

Advancing to step 3:
The number 519 fits into 405 0 times, leaving a remainder of 405.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 405, we end up with 405.
Fetch the next digit (7) from the dividend, attach it to 405 and continue: 4057 / 519

Going ahead to step 4:
The number 519 fits into 4057 7 times, leaving a remainder of 424.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 3633 from 4057 leaves us with 424.
Take the next digit (9) from the dividend and append it to 424, then repeat: 4249 / 519

Advancing to step 5:
If we divide 4249 by 519, we get 8 and a remainder of 97.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 4152 from 4249 to get 97.
Grab the next digit (0) from the dividend, add it to 97, then carry on: 970 / 519

Moving on to step 6:
The number 519 fits into 970 1 times, leaving a remainder of 451.
Use 1 as the next digit of our solution. 
Result so far: 781.0
The remainder is 451 after subtracting 519 from 970.
Bring next digit (9) of the dividend behind the 451 and repeat the process: 4519 / 519

Going ahead to step 7:
4519 divided by 519 is 8 with a remainder of 367.
Record the quotient 8 as the next digit in the result. 
Result so far: 7818.0
If we take 4152 away from 4519, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 8:
The number 519 fits into 3670 7 times, leaving a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 7818.7
Subtract 3633 from 3670 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
519 can be fit into 370 0 times, resulting in a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 7818.7
If we take 0 away from 370, we end up 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 10:
The number 519 fits into 3700 7 times, leaving a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 7818.707
Subtracting 3633 from 3700 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 11:
When dividing 670 by 519, we get 1 with a remainder of 151.
Write down 1 as next digit of the result. 
Result so far: 7818.7071
The remainder is 151 after subtracting 519 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 12:
If we divide 1510 by 519, we get 2 and a remainder of 472.
Put 2 as the next digit of the answer. 
Result so far: 7818.70712
Subtract 1038 from 1510 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 13:
The number 519 fits into 4720 9 times, leaving a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 7818.707129
The remainder is 49 after subtracting 4671 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 14:
If we divide 490 by 519, we get 0 and a remainder of 490.
The next digit of our result is 0. 
Result so far: 7818.707129
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 15:
If we divide 4900 by 519, we get 9 and a remainder of 229.
The number 9 becomes the next digit in our result. 
Result so far: 7818.70712909
Subtract 4671 from 4900 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final outcome is 7818.70712909, with a leftover of 2.29e-07.
