8597609 divided by 778 
We want to divide 8597609 by 778.

Step 1:
8 divided by 778 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 778

On to step 2:
778 can be fit into 85 0 times, resulting in a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 778

Moving on to step 3:
If we divide 859 by 778, we get 1 and a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 778 from 859 leaves us with 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 778

Let's proceed to step 4:
778 can be fit into 817 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 39 after subtracting 778 from 817.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 778

Advancing to step 5:
When dividing 396 by 778, we get 0 with a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtracting 0 from 396 leaves us with 396.
Grab the next digit (0) from the dividend, add it to 396, then carry on: 3960 / 778

Step 6:
The number 778 fits into 3960 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 1105.0
Deduct 3890 from 3960 and we're left with 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 778

Let's proceed to step 7:
When dividing 709 by 778, we get 0 with a remainder of 709.
Use 0 as the next digit of our solution. 
Result so far: 11050.0
Subtracting 0 from 709 leaves us with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Let's proceed to step 8:
When dividing 7090 by 778, we get 9 with a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 11050.9
Deduct 7002 from 7090 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 9:
880 divided by 778 is 1 with a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 11050.91
Deduct 778 from 880 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 10:
The number 778 fits into 1020 1 times, leaving a remainder of 242.
The next digit of our result is 1. 
Result so far: 11050.911
If we take 778 away from 1020, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

After the division, we end up with 11050.911 and a remainder of 0.0242.
