We're dividing 77700285 by 497 
We want to divide 77700285 by 497.

Advancing to step 1:
When dividing 7 by 497, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 497

Going ahead to step 2:
497 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 497

On to step 3:
497 can be fit into 777 1 times, resulting in a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 497 from 777 to get 280.
Fetch the next digit (0) from the dividend, attach it to 280 and continue: 2800 / 497

Advancing to step 4:
The number 497 fits into 2800 5 times, leaving a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 2485 from 2800 leaves us with 315.
Include the next digit (0) from the dividend after 315, then repeat: 3150 / 497

Going ahead to step 5:
If we divide 3150 by 497, we get 6 and a remainder of 168.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Subtracting 2982 from 3150 leaves us with 168.
Grab the next digit (2) from the dividend, add it to 168, then carry on: 1682 / 497

On to step 6:
497 can be fit into 1682 3 times, resulting in a remainder of 191.
The number 3 becomes the next digit in our result. 
Result so far: 1563.0
The remainder is 191 after subtracting 1491 from 1682.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 497

Let's proceed to step 7:
1918 divided by 497 is 3 with a remainder of 427.
Put 3 as the next digit of the answer. 
Result so far: 15633.0
If we take 1491 away from 1918, we end up with 427.
Grab the next digit (5) from the dividend, add it to 427, then carry on: 4275 / 497

Moving on to step 8:
497 goes into 4275 8 times with a remainder of 299.
The number 8 becomes the next digit in our result. 
Result so far: 156338.0
Subtracting 3976 from 4275 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 9:
2990 divided by 497 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 156338.6
The remainder is 8 after subtracting 2982 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 497, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 156338.6
Subtracting 0 from 80 leaves us 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 11:
497 goes into 800 1 times with a remainder of 303.
The next digit of our result is 1. 
Result so far: 156338.601
If we take 497 away from 800, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Let's proceed to step 12:
3030 divided by 497 is 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 156338.6016
The remainder is 48 after subtracting 2982 from 3030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
The number 497 fits into 480 0 times, leaving a remainder of 480.
The next digit of our result is 0. 
Result so far: 156338.6016
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 14:
When dividing 4800 by 497, we get 9 with a remainder of 327.
Record the quotient 9 as the next digit in the result. 
Result so far: 156338.601609
Subtract 4473 from 4800 to get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 15:
497 can be fit into 3270 6 times, resulting in a remainder of 288.
The number 6 becomes the next digit in our result. 
Result so far: 156338.6016096
The remainder is 288 after subtracting 2982 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 16:
497 can be fit into 2880 5 times, resulting in a remainder of 395.
The next digit of our result is 5. 
Result so far: 156338.60160965
Subtracting 2485 from 2880 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

The final outcome is 156338.60160965, with a leftover of 3.95e-07.
