We look at the division of 78111638 by 493 
We want to divide 78111638 by 493.

Let's proceed to step 1:
493 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 493

Step 2:
The number 493 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 493

Going ahead to step 3:
493 goes into 781 1 times with a remainder of 288.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 288 after subtracting 493 from 781.
Grab the next digit (1) from the dividend, add it to 288, then carry on: 2881 / 493

Advancing to step 4:
493 goes into 2881 5 times with a remainder of 416.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2465 away from 2881, we end up with 416.
Append the next digit (1) from the dividend to 416 and continue with: 4161 / 493

Let's proceed to step 5:
When dividing 4161 by 493, we get 8 with a remainder of 217.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Subtract 3944 from 4161 to get 217.
Append the next digit (6) from the dividend to 217 and continue with: 2176 / 493

On to step 6:
493 goes into 2176 4 times with a remainder of 204.
Record the quotient 4 as the next digit in the result. 
Result so far: 1584.0
Subtract 1972 from 2176 to get 204.
Append the next digit (3) from the dividend to 204 and continue with: 2043 / 493

Step 7:
493 goes into 2043 4 times with a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 15844.0
Subtracting 1972 from 2043 leaves us with 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 493

Let's proceed to step 8:
493 goes into 718 1 times with a remainder of 225.
Record the quotient 1 as the next digit in the result. 
Result so far: 158441.0
The remainder is 225 after subtracting 493 from 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 9:
493 can be fit into 2250 4 times, resulting in a remainder of 278.
Put 4 as the next digit of the answer. 
Result so far: 158441.4
Deduct 1972 from 2250 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 10:
When dividing 2780 by 493, we get 5 with a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 158441.45
If we take 2465 away from 2780, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 11:
3150 divided by 493 is 6 with a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 158441.456
The remainder is 192 after subtracting 2958 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 12:
When dividing 1920 by 493, we get 3 with a remainder of 441.
Write down 3 as next digit of the result. 
Result so far: 158441.4563
The remainder is 441 after subtracting 1479 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Moving on to step 13:
When dividing 4410 by 493, we get 8 with a remainder of 466.
Put 8 as the next digit of the answer. 
Result so far: 158441.45638
Subtracting 3944 from 4410 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 14:
The number 493 fits into 4660 9 times, leaving a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 158441.456389
If we subtract 4437 from 4660, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Moving on to step 15:
2230 divided by 493 is 4 with a remainder of 258.
The next digit of our result is 4. 
Result so far: 158441.4563894
The remainder is 258 after subtracting 1972 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 16:
When dividing 2580 by 493, we get 5 with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 158441.45638945
Subtracting 2465 from 2580 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final result is 158441.45638945 with a remainder of 1.15e-07.
