Let's divide 774561 by 78
We want to divide 774561 by 78.

Moving on to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 78

Advancing to step 2:
When dividing 77 by 78, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 78

Moving on to step 3:
If we divide 774 by 78, we get 9 and a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 702 away from 774, we end up with 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 78

Moving on to step 4:
If we divide 725 by 78, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 702 from 725 to get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 78

On to step 5:
236 divided by 78 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 993.0
Subtract 234 from 236 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 78

Going ahead to step 6:
When dividing 21 by 78, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 9930.0
The remainder is 21 after subtracting 0 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
78 can be fit into 210 2 times, resulting in a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 9930.2
Subtracting 156 from 210 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 9930.26
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
When dividing 720 by 78, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 9930.269
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 9930.2692
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
240 divided by 78 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 9930.26923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
If we divide 60 by 78, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 9930.26923
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
If we divide 600 by 78, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 9930.2692307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
540 divided by 78 is 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 9930.26923076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 9930.26923076, and the remainder is 7.2e-08.
