We look at the division of 905405 by 78 
We want to figure out the number of times 905405 can be divided by 78.

On to step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 78

Going ahead to step 2:
78 goes into 90 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 78 from 90 leaves us with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 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
The remainder is 47 after subtracting 78 from 125.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 78

Let's proceed to step 4:
If we divide 474 by 78, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Deduct 468 from 474 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 78

Advancing to step 5:
60 divided by 78 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 1160.0
If we take 0 away from 60, we end up with 60.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 78

Step 6:
The number 78 fits into 605 7 times, leaving a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 11607.0
Deduct 546 from 605 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
When dividing 590 by 78, we get 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 11607.7
If we subtract 546 from 590, we 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.

Step 8:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 11607.75
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
When dividing 500 by 78, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 11607.756
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
78 goes into 320 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 11607.7564
Deduct 312 from 320 and we're left 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.

On to step 11:
78 can be fit into 80 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 11607.75641
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.

Let's proceed to step 12:
78 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11607.75641
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
When dividing 200 by 78, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 11607.7564102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
78 goes into 440 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 11607.75641025
Subtracting 390 from 440 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 11607.75641025 with a remainder of 5e-08.
