We divide 5420078 by 510
We want to divide 5420078 by 510.

On to step 1:
When dividing 5 by 510, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 510

Let's proceed to step 2:
510 can be fit into 54 0 times, resulting in a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 510

Let's proceed to step 3:
When dividing 542 by 510, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 510 from 542 to get 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 510

Moving on to step 4:
The number 510 fits into 320 0 times, leaving a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 320 to get 320.
Fetch the next digit (0) from the dividend, attach it to 320 and continue: 3200 / 510

Going ahead to step 5:
510 can be fit into 3200 6 times, resulting in a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we subtract 3060 from 3200, we get 140.
Include the next digit (7) from the dividend after 140, then repeat: 1407 / 510

Step 6:
1407 divided by 510 is 2 with a remainder of 387.
Put 2 as the next digit of the answer. 
Result so far: 1062.0
Deduct 1020 from 1407 and we're left with 387.
Include the next digit (8) from the dividend after 387, then repeat: 3878 / 510

Advancing to step 7:
510 goes into 3878 7 times with a remainder of 308.
The number 7 becomes the next digit in our result. 
Result so far: 10627.0
The remainder is 308 after subtracting 3570 from 3878.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 8:
The number 510 fits into 3080 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 10627.6
Subtracting 3060 from 3080 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
510 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 10627.6
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
510 can be fit into 2000 3 times, resulting in a remainder of 470.
The next digit of our result is 3. 
Result so far: 10627.603
If we subtract 1530 from 2000, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 11:
510 goes into 4700 9 times with a remainder of 110.
The next digit of our result is 9. 
Result so far: 10627.6039
Deduct 4590 from 4700 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 12:
510 can be fit into 1100 2 times, resulting in a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 10627.60392
If we take 1020 away from 1100, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
510 goes into 800 1 times with a remainder of 290.
Put 1 as the next digit of the answer. 
Result so far: 10627.603921
Subtract 510 from 800 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 14:
When dividing 2900 by 510, we get 5 with a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 10627.6039215
If we subtract 2550 from 2900, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 15:
If we divide 3500 by 510, we get 6 and a remainder of 440.
Write down 6 as next digit of the result. 
Result so far: 10627.60392156
If we take 3060 away from 3500, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 10627.60392156, with a leftover of 4.4e-07.
