989912 ÷ 78 
Let's see how many times 78 fits into 989912.

Advancing to step 1:
9 divided by 78 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 78

Going ahead to step 2:
98 divided by 78 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 78 from 98 leaves us with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 78

Step 3:
When dividing 209 by 78, we get 2 with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 156 from 209 and we're left with 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 78

On to step 4:
If we divide 539 by 78, we get 6 and a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 126.0
The remainder is 71 after subtracting 468 from 539.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 78

Let's proceed to step 5:
When dividing 711 by 78, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 1269.0
Deduct 702 from 711 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 78

On to step 6:
The number 78 fits into 92 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 12691.0
If we take 78 away from 92, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
The number 78 fits into 140 1 times, leaving a remainder of 62.
The next digit of our result is 1. 
Result so far: 12691.1
Deduct 78 from 140 and we're left 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:
If we divide 620 by 78, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 12691.17
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
740 divided by 78 is 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 12691.179
Deduct 702 from 740 and we're left 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:
When dividing 380 by 78, we get 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 12691.1794
Subtract 312 from 380 to get 68.
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:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 12691.17948
Subtracting 624 from 680 leaves us 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.

Step 12:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 12691.179487
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.

Moving on to step 13:
140 divided by 78 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 12691.1794871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
When dividing 620 by 78, we get 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 12691.17948717
Deduct 546 from 620 and we're left with 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 12691.17948717 with a remaining 7.4e-08.
