We look at the division of 987728 by 78 
Our goal is to divide 987728 by 78.

Step 1:
If we divide 9 by 78, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 78

Let's proceed to step 2:
If we divide 98 by 78, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 78 from 98 leaves us with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 78

On to step 3:
If we divide 207 by 78, we get 2 and a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 156 from 207, we get 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 78

On to step 4:
517 divided by 78 is 6 with a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtract 468 from 517 to get 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 78

On to step 5:
78 can be fit into 492 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1266.0
The remainder is 24 after subtracting 468 from 492.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 78

On to step 6:
78 can be fit into 248 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 12663.0
Subtract 234 from 248 to 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.

Advancing to step 7:
If we divide 140 by 78, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 12663.1
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
78 goes into 620 7 times with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 12663.17
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
When dividing 740 by 78, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 12663.179
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
78 goes into 380 4 times with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 12663.1794
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
680 divided by 78 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 12663.17948
Deduct 624 from 680 and we're left 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.

Advancing to step 12:
If we divide 560 by 78, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 12663.179487
Subtract 546 from 560 to 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 13:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 12663.1794871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
78 goes into 620 7 times with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 12663.17948717
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 12663.17948717 with a remaining 7.4e-08.
