Let's divide 78117779 by 191
Let's see how many times 191 fits into 78117779.

Going ahead to step 1:
191 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 191

On to step 2:
If we divide 78 by 191, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 191

On to step 3:
191 can be fit into 781 4 times, resulting in a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 764 away from 781, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 191

Step 4:
191 goes into 171 0 times with a remainder of 171.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 171 after subtracting 0 from 171.
Include the next digit (7) from the dividend after 171, then repeat: 1717 / 191

Moving on to step 5:
If we divide 1717 by 191, we get 8 and a remainder of 189.
The next digit of our result is 8. 
Result so far: 408.0
Subtracting 1528 from 1717 leaves us with 189.
Grab the next digit (7) from the dividend, add it to 189, then carry on: 1897 / 191

Going ahead to step 6:
The number 191 fits into 1897 9 times, leaving a remainder of 178.
Write down 9 as next digit of the result. 
Result so far: 4089.0
Deduct 1719 from 1897 and we're left with 178.
Include the next digit (7) from the dividend after 178, then repeat: 1787 / 191

Moving on to step 7:
191 goes into 1787 9 times with a remainder of 68.
The next digit of our result is 9. 
Result so far: 40899.0
If we subtract 1719 from 1787, we get 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 191

Moving on to step 8:
When dividing 689 by 191, we get 3 with a remainder of 116.
Put 3 as the next digit of the answer. 
Result so far: 408993.0
If we take 573 away from 689, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 9:
When dividing 1160 by 191, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 408993.6
If we subtract 1146 from 1160, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
When dividing 140 by 191, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 408993.6
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
191 can be fit into 1400 7 times, resulting in a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 408993.607
If we subtract 1337 from 1400, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 12:
When dividing 630 by 191, we get 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 408993.6073
If we take 573 away from 630, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
191 goes into 570 2 times with a remainder of 188.
Write down 2 as next digit of the result. 
Result so far: 408993.60732
Subtracting 382 from 570 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 14:
191 goes into 1880 9 times with a remainder of 161.
The next digit of our result is 9. 
Result so far: 408993.607329
Subtracting 1719 from 1880 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 15:
The number 191 fits into 1610 8 times, leaving a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 408993.6073298
If we take 1528 away from 1610, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 16:
820 divided by 191 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 408993.60732984
If we take 764 away from 820, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 408993.60732984 with a balance of 5.6e-08.
