We divide 15255064 by 77
We're looking to find how many times 77 goes into 15255064.

Going ahead to step 1:
77 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 77

Moving on to step 2:
77 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 77

Advancing to step 3:
152 divided by 77 is 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 75 after subtracting 77 from 152.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 77

Going ahead to step 4:
77 goes into 755 9 times with a remainder of 62.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 693 from 755 and we're left with 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 77

Step 5:
77 can be fit into 625 8 times, resulting in a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 198.0
The remainder is 9 after subtracting 616 from 625.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 77

On to step 6:
77 goes into 90 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1981.0
Subtract 77 from 90 to get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 77

Step 7:
136 divided by 77 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 19811.0
If we take 77 away from 136, we end up with 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 77

Advancing to step 8:
The number 77 fits into 594 7 times, leaving a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 198117.0
Subtract 539 from 594 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
77 can be fit into 550 7 times, resulting in a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 198117.7
Deduct 539 from 550 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
If we divide 110 by 77, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 198117.71
If we take 77 away from 110, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
The number 77 fits into 330 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 198117.714
Subtracting 308 from 330 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
220 divided by 77 is 2 with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 198117.7142
Subtracting 154 from 220 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
The number 77 fits into 660 8 times, leaving a remainder of 44.
The next digit of our result is 8. 
Result so far: 198117.71428
The remainder is 44 after subtracting 616 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
77 goes into 440 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 198117.714285
Subtract 385 from 440 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 15:
If we divide 550 by 77, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 198117.7142857
If we take 539 away from 550, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 16:
77 can be fit into 110 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 198117.71428571
If we subtract 77 from 110, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

In conclusion, the division gives 198117.71428571 with a balance of 3.3e-08.
