597637 ÷ 78 
Our goal is to divide 597637 by 78.

Let's proceed to step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 78

Step 2:
When dividing 59 by 78, we get 0 with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Bring next digit (7) of the dividend behind the 59 and repeat the process: 597 / 78

Step 3:
597 divided by 78 is 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 546 from 597, we get 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 78

Going ahead to step 4:
516 divided by 78 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 468 from 516 and we're left with 48.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 78

Advancing to step 5:
78 goes into 483 6 times with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 766.0
Deduct 468 from 483 and we're left with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 78

On to step 6:
157 divided by 78 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 7662.0
Subtract 156 from 157 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 78 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7662.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 7662.01
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 7662.012
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
When dividing 640 by 78, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7662.0128
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
If we divide 160 by 78, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7662.01282
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7662.01282
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
The number 78 fits into 400 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 7662.0128205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 7662.01282051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 7662.01282051 with a remainder of 2.2e-08.
