986864 ÷ 78 
Let's see how many times 78 fits into 986864.

On to step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 78

On to step 2:
98 divided by 78 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 78 from 98 and we're left with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 78

Going ahead to step 3:
When dividing 206 by 78, we get 2 with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 156 from 206 to get 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 78

Going ahead to step 4:
78 can be fit into 508 6 times, resulting in a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtract 468 from 508 to get 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 78

On to step 5:
When dividing 406 by 78, we get 5 with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 1265.0
If we take 390 away from 406, we end up with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 78

Step 6:
The number 78 fits into 164 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12652.0
Subtract 156 from 164 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
When dividing 80 by 78, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 12652.1
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
If we divide 20 by 78, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12652.1
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 12652.102
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
When dividing 440 by 78, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 12652.1025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
If we divide 500 by 78, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 12652.10256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
78 goes into 320 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 12652.102564
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
80 divided by 78 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 12652.1025641
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
If we divide 20 by 78, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 12652.1025641
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 12652.1025641 with a remaining 2e-08.
