Let's divide 901878 by 78
We're looking to find how many times 78 goes into 901878.

Let's proceed to step 1:
78 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 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
If we take 78 away from 90, we end up with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 78

Let's proceed to step 3:
When dividing 121 by 78, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 43 after subtracting 78 from 121.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 78

Advancing to step 4:
438 divided by 78 is 5 with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtracting 390 from 438 leaves us with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 78

Step 5:
78 can be fit into 487 6 times, resulting in a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 1156.0
Subtract 468 from 487 to get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 78

Advancing to step 6:
If we divide 198 by 78, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 11562.0
If we subtract 156 from 198, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 78 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 11562.5
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 11562.53
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 11562.538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 11562.5384
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
When dividing 480 by 78, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 11562.53846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 11562.538461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 11562.5384615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
If we divide 300 by 78, we get 3 and a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 11562.53846153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 11562.53846153, with a leftover of 6.6e-08.
