901169 divided by 78 
Our goal is to divide 901169 by 78.

Step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 78

Advancing to step 2:
When dividing 90 by 78, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 78 from 90 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 78

Going ahead to step 3:
If we divide 121 by 78, we get 1 and a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 78 from 121 and we're left with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 78

Going ahead to step 4:
431 divided by 78 is 5 with a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Deduct 390 from 431 and we're left with 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 78

Advancing to step 5:
78 can be fit into 416 5 times, resulting in a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 1155.0
Subtracting 390 from 416 leaves us with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 78

Let's proceed to step 6:
78 goes into 269 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 11553.0
If we take 234 away from 269, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
If we divide 350 by 78, we get 4 and a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 11553.4
Subtract 312 from 350 to get 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 8:
When dividing 380 by 78, we get 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 11553.44
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.

The final outcome is 11553.44, with a leftover of 0.068.
