77270296 ÷ 507 
Our goal is to divide 77270296 by 507.

On to step 1:
If we divide 7 by 507, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 507

Step 2:
The number 507 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 507

Going ahead to step 3:
507 can be fit into 772 1 times, resulting in a remainder of 265.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 507 from 772 and we're left with 265.
Bring next digit (7) of the dividend behind the 265 and repeat the process: 2657 / 507

Going ahead to step 4:
If we divide 2657 by 507, we get 5 and a remainder of 122.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 2535 from 2657 to get 122.
Fetch the next digit (0) from the dividend, attach it to 122 and continue: 1220 / 507

Step 5:
507 can be fit into 1220 2 times, resulting in a remainder of 206.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we subtract 1014 from 1220, we get 206.
Append the next digit (2) from the dividend to 206 and continue with: 2062 / 507

On to step 6:
2062 divided by 507 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 1524.0
If we subtract 2028 from 2062, we get 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 507

Let's proceed to step 7:
507 can be fit into 349 0 times, resulting in a remainder of 349.
The number 0 becomes the next digit in our result. 
Result so far: 15240.0
Subtracting 0 from 349 leaves us with 349.
Fetch the next digit (6) from the dividend, attach it to 349 and continue: 3496 / 507

On to step 8:
507 can be fit into 3496 6 times, resulting in a remainder of 454.
The number 6 becomes the next digit in our result. 
Result so far: 152406.0
Deduct 3042 from 3496 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 9:
When dividing 4540 by 507, we get 8 with a remainder of 484.
The number 8 becomes the next digit in our result. 
Result so far: 152406.8
Deduct 4056 from 4540 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 10:
The number 507 fits into 4840 9 times, leaving a remainder of 277.
Record the quotient 9 as the next digit in the result. 
Result so far: 152406.89
The remainder is 277 after subtracting 4563 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 11:
507 goes into 2770 5 times with a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 152406.895
If we subtract 2535 from 2770, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 12:
507 can be fit into 2350 4 times, resulting in a remainder of 322.
Use 4 as the next digit of our solution. 
Result so far: 152406.8954
Subtract 2028 from 2350 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 13:
The number 507 fits into 3220 6 times, leaving a remainder of 178.
Put 6 as the next digit of the answer. 
Result so far: 152406.89546
Subtract 3042 from 3220 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 14:
507 goes into 1780 3 times with a remainder of 259.
Use 3 as the next digit of our solution. 
Result so far: 152406.895463
Subtract 1521 from 1780 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 15:
If we divide 2590 by 507, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 152406.8954635
Deduct 2535 from 2590 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 16:
550 divided by 507 is 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 152406.89546351
If we subtract 507 from 550, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

In conclusion, the division gives 152406.89546351 with a balance of 4.3e-08.
