Let's divide 78186219 by 261
Our goal is to divide 78186219 by 261.

Going ahead to step 1:
261 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 261

Let's proceed to step 2:
261 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 261

Let's proceed to step 3:
261 can be fit into 781 2 times, resulting in a remainder of 259.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 522 from 781 leaves us with 259.
Append the next digit (8) from the dividend to 259 and continue with: 2598 / 261

Advancing to step 4:
261 can be fit into 2598 9 times, resulting in a remainder of 249.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 2349 from 2598 leaves us with 249.
Grab the next digit (6) from the dividend, add it to 249, then carry on: 2496 / 261

Going ahead to step 5:
2496 divided by 261 is 9 with a remainder of 147.
The number 9 becomes the next digit in our result. 
Result so far: 299.0
If we subtract 2349 from 2496, we get 147.
Append the next digit (2) from the dividend to 147 and continue with: 1472 / 261

Advancing to step 6:
The number 261 fits into 1472 5 times, leaving a remainder of 167.
The next digit of our result is 5. 
Result so far: 2995.0
Deduct 1305 from 1472 and we're left with 167.
Take the next digit (1) from the dividend and append it to 167, then repeat: 1671 / 261

Let's proceed to step 7:
If we divide 1671 by 261, we get 6 and a remainder of 105.
The number 6 becomes the next digit in our result. 
Result so far: 29956.0
Subtracting 1566 from 1671 leaves us with 105.
Bring next digit (9) of the dividend behind the 105 and repeat the process: 1059 / 261

Step 8:
261 goes into 1059 4 times with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 299564.0
Deduct 1044 from 1059 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
The number 261 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 299564.0
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
The number 261 fits into 1500 5 times, leaving a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 299564.05
If we take 1305 away from 1500, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 11:
261 can be fit into 1950 7 times, resulting in a remainder of 123.
Record the quotient 7 as the next digit in the result. 
Result so far: 299564.057
If we take 1827 away from 1950, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 12:
261 goes into 1230 4 times with a remainder of 186.
The number 4 becomes the next digit in our result. 
Result so far: 299564.0574
Subtracting 1044 from 1230 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 13:
When dividing 1860 by 261, we get 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 299564.05747
Deduct 1827 from 1860 and we're left 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.

On to step 14:
330 divided by 261 is 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 299564.057471
If we take 261 away from 330, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 15:
When dividing 690 by 261, we get 2 with a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 299564.0574712
Subtract 522 from 690 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 16:
1680 divided by 261 is 6 with a remainder of 114.
The next digit of our result is 6. 
Result so far: 299564.05747126
If we take 1566 away from 1680, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

After the division, we end up with 299564.05747126 and a remainder of 1.14e-07.
