We divide 61866 by 78
We want to figure out the number of times 61866 can be divided by 78.

Let's proceed to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 78

Let's proceed to step 2:
78 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 78

Let's proceed to step 3:
If we divide 618 by 78, we get 7 and a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 546 from 618, we get 72.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 78

Moving on to step 4:
If we divide 726 by 78, we get 9 and a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtracting 702 from 726 leaves us with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 78

Advancing to step 5:
78 goes into 246 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 793.0
Deduct 234 from 246 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 6:
120 divided by 78 is 1 with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 793.1
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
If we divide 420 by 78, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 793.15
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
78 goes into 300 3 times with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 793.153
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
When dividing 660 by 78, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 793.1538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
78 goes into 360 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 793.15384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
When dividing 480 by 78, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 793.153846
If we take 468 away from 480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
78 goes into 120 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 793.1538461
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
If we divide 420 by 78, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 793.15384615
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 793.15384615 with a remainder of 3e-08.
