We look at the division of 905120 by 78 
We want to divide 905120 by 78.

On to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 78

Going ahead to step 2:
78 can be fit into 90 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 78 from 90 and we're left with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 78

Advancing to step 3:
When dividing 125 by 78, we get 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 78 from 125 and we're left with 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 78

Let's proceed to step 4:
471 divided by 78 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 116.0
If we take 468 away from 471, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 78

Going ahead to step 5:
78 can be fit into 32 0 times, resulting in a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 1160.0
Subtract 0 from 32 to get 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 78

Advancing to step 6:
When dividing 320 by 78, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11604.0
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 11604.1
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 78 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11604.1
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
If we divide 200 by 78, we get 2 and a remainder of 44.
The next digit of our result is 2. 
Result so far: 11604.102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11604.1025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
78 goes into 500 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 11604.10256
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
320 divided by 78 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11604.102564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
78 goes into 80 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11604.1025641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
20 divided by 78 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11604.1025641
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 11604.1025641 with a remainder of 2e-08.
