We look at the division of 77591931 by 608 
Let's see how many times 608 fits into 77591931.

On to step 1:
If we divide 7 by 608, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 608

Let's proceed to step 2:
608 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 608

On to step 3:
The number 608 fits into 775 1 times, leaving a remainder of 167.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 608 from 775, we get 167.
Append the next digit (9) from the dividend to 167 and continue with: 1679 / 608

Step 4:
The number 608 fits into 1679 2 times, leaving a remainder of 463.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1216 from 1679 and we're left with 463.
Include the next digit (1) from the dividend after 463, then repeat: 4631 / 608

Advancing to step 5:
If we divide 4631 by 608, we get 7 and a remainder of 375.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Subtracting 4256 from 4631 leaves us with 375.
Grab the next digit (9) from the dividend, add it to 375, then carry on: 3759 / 608

On to step 6:
If we divide 3759 by 608, we get 6 and a remainder of 111.
Use 6 as the next digit of our solution. 
Result so far: 1276.0
Subtract 3648 from 3759 to get 111.
Include the next digit (3) from the dividend after 111, then repeat: 1113 / 608

On to step 7:
If we divide 1113 by 608, we get 1 and a remainder of 505.
Use 1 as the next digit of our solution. 
Result so far: 12761.0
Subtract 608 from 1113 to get 505.
Grab the next digit (1) from the dividend, add it to 505, then carry on: 5051 / 608

Going ahead to step 8:
When dividing 5051 by 608, we get 8 with a remainder of 187.
The next digit of our result is 8. 
Result so far: 127618.0
If we take 4864 away from 5051, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
The number 608 fits into 1870 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 127618.3
Subtracting 1824 from 1870 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
460 divided by 608 is 0 with a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 127618.3
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 11:
The number 608 fits into 4600 7 times, leaving a remainder of 344.
Record the quotient 7 as the next digit in the result. 
Result so far: 127618.307
If we subtract 4256 from 4600, we get 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 12:
608 goes into 3440 5 times with a remainder of 400.
The next digit of our result is 5. 
Result so far: 127618.3075
Deduct 3040 from 3440 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
The number 608 fits into 4000 6 times, leaving a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 127618.30756
The remainder is 352 after subtracting 3648 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 14:
3520 divided by 608 is 5 with a remainder of 480.
Put 5 as the next digit of the answer. 
Result so far: 127618.307565
The remainder is 480 after subtracting 3040 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 15:
If we divide 4800 by 608, we get 7 and a remainder of 544.
Write down 7 as next digit of the result. 
Result so far: 127618.3075657
The remainder is 544 after subtracting 4256 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 16:
608 goes into 5440 8 times with a remainder of 576.
The number 8 becomes the next digit in our result. 
Result so far: 127618.30756578
Deduct 4864 from 5440 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final result is 127618.30756578 with a remainder of 5.76e-07.
