Let's divide 78145251 by 191
Our goal is to divide 78145251 by 191.

On to step 1:
If we divide 7 by 191, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 191

Advancing to step 2:
78 divided by 191 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 191

Step 3:
If we divide 781 by 191, we get 4 and a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 764 from 781 to get 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 191

Advancing to step 4:
If we divide 174 by 191, we get 0 and a remainder of 174.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 174, we get 174.
Include the next digit (5) from the dividend after 174, then repeat: 1745 / 191

Let's proceed to step 5:
If we divide 1745 by 191, we get 9 and a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 409.0
Subtract 1719 from 1745 to get 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 191

Let's proceed to step 6:
191 goes into 262 1 times with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 4091.0
If we subtract 191 from 262, we get 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 191

Advancing to step 7:
The number 191 fits into 715 3 times, leaving a remainder of 142.
The next digit of our result is 3. 
Result so far: 40913.0
Subtracting 573 from 715 leaves us with 142.
Take the next digit (1) from the dividend and append it to 142, then repeat: 1421 / 191

Moving on to step 8:
191 can be fit into 1421 7 times, resulting in a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 409137.0
If we take 1337 away from 1421, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
The number 191 fits into 840 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 409137.4
The remainder is 76 after subtracting 764 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
191 goes into 760 3 times with a remainder of 187.
Put 3 as the next digit of the answer. 
Result so far: 409137.43
If we take 573 away from 760, 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.

Moving on to step 11:
If we divide 1870 by 191, we get 9 and a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 409137.439
If we subtract 1719 from 1870, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 12:
1510 divided by 191 is 7 with a remainder of 173.
Use 7 as the next digit of our solution. 
Result so far: 409137.4397
The remainder is 173 after subtracting 1337 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 13:
1730 divided by 191 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 409137.43979
Subtract 1719 from 1730 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
When dividing 110 by 191, we get 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 409137.43979
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 15:
When dividing 1100 by 191, we get 5 with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 409137.4397905
Deduct 955 from 1100 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 16:
1450 divided by 191 is 7 with a remainder of 113.
Write down 7 as next digit of the result. 
Result so far: 409137.43979057
Subtract 1337 from 1450 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

The final result is 409137.43979057 with a remainder of 1.13e-07.
