We divide 985910 by 78
We want to figure out the number of times 985910 can be divided by 78.

Moving on to step 1:
The number 78 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 78

Step 2:
78 can be fit into 98 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 78 from 98 to get 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 78

Step 3:
205 divided by 78 is 2 with a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 49 after subtracting 156 from 205.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 78

Moving on to step 4:
499 divided by 78 is 6 with a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 126.0
If we take 468 away from 499, we end up with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 78

On to step 5:
78 goes into 311 3 times with a remainder of 77.
The next digit of our result is 3. 
Result so far: 1263.0
If we take 234 away from 311, we end up with 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 78

Step 6:
770 divided by 78 is 9 with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 12639.0
Subtract 702 from 770 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.

Step 7:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 12639.8
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 12639.87
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.

Going ahead to step 9:
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: 12639.871
If we take 78 away from 140, we end up 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.

Step 10:
620 divided by 78 is 7 with a remainder of 74.
The next digit of our result is 7. 
Result so far: 12639.8717
The remainder is 74 after subtracting 546 from 620.
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 11:
740 divided by 78 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 12639.87179
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.

Moving on to step 12:
380 divided by 78 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 12639.871794
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.

On to step 13:
680 divided by 78 is 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 12639.8717948
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.

Going ahead to step 14:
The number 78 fits into 560 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 12639.87179487
Deduct 546 from 560 and we're left 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.

The final outcome is 12639.87179487, with a leftover of 1.4e-08.
