We divide 909778 by 78
We want to figure out the number of times 909778 can be divided by 78.

On to step 1:
9 divided by 78 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 78

Step 2:
If we divide 90 by 78, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we take 78 away from 90, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 78

Let's proceed to step 3:
If we divide 129 by 78, we get 1 and a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 78 from 129 and we're left with 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 78

Moving on to step 4:
The number 78 fits into 517 6 times, leaving a remainder of 49.
The next digit of our result is 6. 
Result so far: 116.0
Subtracting 468 from 517 leaves us with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 78

Step 5:
78 goes into 497 6 times with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 1166.0
The remainder is 29 after subtracting 468 from 497.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 78

Let's proceed to step 6:
The number 78 fits into 298 3 times, leaving a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 11663.0
Deduct 234 from 298 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
If we divide 640 by 78, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 11663.8
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
When dividing 160 by 78, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 11663.82
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11663.82
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11663.8205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 78, we get 1 and a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 11663.82051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 11663.820512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 11663.8205128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
78 goes into 160 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 11663.82051282
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 11663.82051282, with a leftover of 4e-09.
