We're dividing 76449777 by 515 
We're looking to find how many times 515 goes into 76449777.

Advancing to step 1:
7 divided by 515 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 515

Advancing to step 2:
515 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 515

Advancing to step 3:
515 can be fit into 764 1 times, resulting in a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 249 after subtracting 515 from 764.
Append the next digit (4) from the dividend to 249 and continue with: 2494 / 515

On to step 4:
515 can be fit into 2494 4 times, resulting in a remainder of 434.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2060 from 2494, we get 434.
Append the next digit (9) from the dividend to 434 and continue with: 4349 / 515

Moving on to step 5:
515 can be fit into 4349 8 times, resulting in a remainder of 229.
The next digit of our result is 8. 
Result so far: 148.0
If we subtract 4120 from 4349, we get 229.
Take the next digit (7) from the dividend and append it to 229, then repeat: 2297 / 515

On to step 6:
2297 divided by 515 is 4 with a remainder of 237.
The number 4 becomes the next digit in our result. 
Result so far: 1484.0
Subtracting 2060 from 2297 leaves us with 237.
Take the next digit (7) from the dividend and append it to 237, then repeat: 2377 / 515

Advancing to step 7:
If we divide 2377 by 515, we get 4 and a remainder of 317.
Use 4 as the next digit of our solution. 
Result so far: 14844.0
Deduct 2060 from 2377 and we're left with 317.
Fetch the next digit (7) from the dividend, attach it to 317 and continue: 3177 / 515

Moving on to step 8:
515 goes into 3177 6 times with a remainder of 87.
Record the quotient 6 as the next digit in the result. 
Result so far: 148446.0
If we subtract 3090 from 3177, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 9:
515 can be fit into 870 1 times, resulting in a remainder of 355.
Record the quotient 1 as the next digit in the result. 
Result so far: 148446.1
Subtracting 515 from 870 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 10:
If we divide 3550 by 515, we get 6 and a remainder of 460.
Record the quotient 6 as the next digit in the result. 
Result so far: 148446.16
If we subtract 3090 from 3550, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
When dividing 4600 by 515, we get 8 with a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 148446.168
If we take 4120 away from 4600, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
When dividing 4800 by 515, we get 9 with a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 148446.1689
The remainder is 165 after subtracting 4635 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 13:
The number 515 fits into 1650 3 times, leaving a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 148446.16893
Subtracting 1545 from 1650 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 14:
If we divide 1050 by 515, we get 2 and a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 148446.168932
If we subtract 1030 from 1050, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
The number 515 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 148446.168932
Subtract 0 from 200 to 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.

Let's proceed to step 16:
The number 515 fits into 2000 3 times, leaving a remainder of 455.
Put 3 as the next digit of the answer. 
Result so far: 148446.16893203
Subtract 1545 from 2000 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

The final outcome is 148446.16893203, with a leftover of 4.55e-07.
