We're dividing 77073499 by 506 
We want to figure out the number of times 77073499 can be divided by 506.

On to step 1:
506 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 506

On to step 2:
506 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 506

Going ahead to step 3:
The number 506 fits into 770 1 times, leaving a remainder of 264.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 506 away from 770, we end up with 264.
Fetch the next digit (7) from the dividend, attach it to 264 and continue: 2647 / 506

Let's proceed to step 4:
506 can be fit into 2647 5 times, resulting in a remainder of 117.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 2530 from 2647 leaves us with 117.
Take the next digit (3) from the dividend and append it to 117, then repeat: 1173 / 506

Let's proceed to step 5:
506 goes into 1173 2 times with a remainder of 161.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we subtract 1012 from 1173, we get 161.
Take the next digit (4) from the dividend and append it to 161, then repeat: 1614 / 506

On to step 6:
The number 506 fits into 1614 3 times, leaving a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 1523.0
Subtract 1518 from 1614 to get 96.
Append the next digit (9) from the dividend to 96 and continue with: 969 / 506

Going ahead to step 7:
506 can be fit into 969 1 times, resulting in a remainder of 463.
The next digit of our result is 1. 
Result so far: 15231.0
Subtracting 506 from 969 leaves us with 463.
Take the next digit (9) from the dividend and append it to 463, then repeat: 4639 / 506

On to step 8:
4639 divided by 506 is 9 with a remainder of 85.
Record the quotient 9 as the next digit in the result. 
Result so far: 152319.0
The remainder is 85 after subtracting 4554 from 4639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 9:
506 goes into 850 1 times with a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 152319.1
If we take 506 away from 850, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 10:
When dividing 3440 by 506, we get 6 with a remainder of 404.
Put 6 as the next digit of the answer. 
Result so far: 152319.16
The remainder is 404 after subtracting 3036 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 11:
When dividing 4040 by 506, we get 7 with a remainder of 498.
Use 7 as the next digit of our solution. 
Result so far: 152319.167
Subtract 3542 from 4040 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 12:
4980 divided by 506 is 9 with a remainder of 426.
The number 9 becomes the next digit in our result. 
Result so far: 152319.1679
The remainder is 426 after subtracting 4554 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 13:
The number 506 fits into 4260 8 times, leaving a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 152319.16798
Subtracting 4048 from 4260 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 14:
When dividing 2120 by 506, we get 4 with a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 152319.167984
Subtracting 2024 from 2120 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 15:
If we divide 960 by 506, we get 1 and a remainder of 454.
Record the quotient 1 as the next digit in the result. 
Result so far: 152319.1679841
Subtract 506 from 960 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 16:
506 can be fit into 4540 8 times, resulting in a remainder of 492.
Put 8 as the next digit of the answer. 
Result so far: 152319.16798418
Subtract 4048 from 4540 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Our division results in 152319.16798418 with a remaining 4.92e-07.
