Let's divide 77454846 by 510
Let's see how many times 510 fits into 77454846.

Going ahead to step 1:
7 divided by 510 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 510

Step 2:
510 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 510

Step 3:
774 divided by 510 is 1 with a remainder of 264.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 510 away from 774, we end up with 264.
Append the next digit (5) from the dividend to 264 and continue with: 2645 / 510

Let's proceed to step 4:
If we divide 2645 by 510, we get 5 and a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2550 from 2645 to get 95.
Append the next digit (4) from the dividend to 95 and continue with: 954 / 510

Going ahead to step 5:
510 can be fit into 954 1 times, resulting in a remainder of 444.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Subtract 510 from 954 to get 444.
Include the next digit (8) from the dividend after 444, then repeat: 4448 / 510

Let's proceed to step 6:
The number 510 fits into 4448 8 times, leaving a remainder of 368.
Use 8 as the next digit of our solution. 
Result so far: 1518.0
Deduct 4080 from 4448 and we're left with 368.
Fetch the next digit (4) from the dividend, attach it to 368 and continue: 3684 / 510

Going ahead to step 7:
When dividing 3684 by 510, we get 7 with a remainder of 114.
Put 7 as the next digit of the answer. 
Result so far: 15187.0
The remainder is 114 after subtracting 3570 from 3684.
Take the next digit (6) from the dividend and append it to 114, then repeat: 1146 / 510

Going ahead to step 8:
510 goes into 1146 2 times with a remainder of 126.
Put 2 as the next digit of the answer. 
Result so far: 151872.0
If we subtract 1020 from 1146, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 9:
If we divide 1260 by 510, we get 2 and a remainder of 240.
The next digit of our result is 2. 
Result so far: 151872.2
Deduct 1020 from 1260 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
510 can be fit into 2400 4 times, resulting in a remainder of 360.
Write down 4 as next digit of the result. 
Result so far: 151872.24
The remainder is 360 after subtracting 2040 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 11:
3600 divided by 510 is 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 151872.247
Subtracting 3570 from 3600 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
300 divided by 510 is 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 151872.247
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
When dividing 3000 by 510, we get 5 with a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 151872.24705
If we take 2550 away from 3000, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 14:
The number 510 fits into 4500 8 times, leaving a remainder of 420.
Put 8 as the next digit of the answer. 
Result so far: 151872.247058
Deduct 4080 from 4500 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 15:
510 goes into 4200 8 times with a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 151872.2470588
Subtracting 4080 from 4200 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 151872.2470588, with a leftover of 1.2e-06.
