77657505 ÷ 215 
Our goal is to divide 77657505 by 215.

On to step 1:
If we divide 7 by 215, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 215

Going ahead to step 2:
When dividing 77 by 215, we get 0 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.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 215

Going ahead to step 3:
215 can be fit into 776 3 times, resulting in a remainder of 131.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 645 from 776 leaves us with 131.
Append the next digit (5) from the dividend to 131 and continue with: 1315 / 215

Let's proceed to step 4:
1315 divided by 215 is 6 with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 1290 away from 1315, we end up with 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 215

Advancing to step 5:
If we divide 257 by 215, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 361.0
Subtracting 215 from 257 leaves us with 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 215

On to step 6:
215 can be fit into 425 1 times, resulting in a remainder of 210.
The number 1 becomes the next digit in our result. 
Result so far: 3611.0
If we take 215 away from 425, we end up with 210.
Append the next digit (0) from the dividend to 210 and continue with: 2100 / 215

On to step 7:
215 can be fit into 2100 9 times, resulting in a remainder of 165.
Put 9 as the next digit of the answer. 
Result so far: 36119.0
Subtract 1935 from 2100 to get 165.
Take the next digit (5) from the dividend and append it to 165, then repeat: 1655 / 215

Advancing to step 8:
215 can be fit into 1655 7 times, resulting in a remainder of 150.
Write down 7 as next digit of the result. 
Result so far: 361197.0
The remainder is 150 after subtracting 1505 from 1655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
215 goes into 1500 6 times with a remainder of 210.
The number 6 becomes the next digit in our result. 
Result so far: 361197.6
Subtract 1290 from 1500 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
215 goes into 2100 9 times with a remainder of 165.
Put 9 as the next digit of the answer. 
Result so far: 361197.69
Deduct 1935 from 2100 and we're left with 165.
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 11:
1650 divided by 215 is 7 with a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 361197.697
The remainder is 145 after subtracting 1505 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 12:
The number 215 fits into 1450 6 times, leaving a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 361197.6976
Subtract 1290 from 1450 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
215 can be fit into 1600 7 times, resulting in a remainder of 95.
Record the quotient 7 as the next digit in the result. 
Result so far: 361197.69767
If we subtract 1505 from 1600, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 14:
The number 215 fits into 950 4 times, leaving a remainder of 90.
Write down 4 as next digit of the result. 
Result so far: 361197.697674
If we subtract 860 from 950, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
215 can be fit into 900 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 361197.6976744
Subtracting 860 from 900 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 361197.6976744 with a balance of 4e-07.
