402597 ÷ 66 
We want to divide 402597 by 66.

Going ahead to step 1:
4 divided by 66 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 66

Advancing to step 2:
66 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 66

Going ahead to step 3:
When dividing 402 by 66, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 396 from 402 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 66

Moving on to step 4:
65 divided by 66 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 60.0
If we subtract 0 from 65, we get 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 66

Going ahead to step 5:
66 can be fit into 659 9 times, resulting in a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 609.0
Deduct 594 from 659 and we're left with 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 66

On to step 6:
When dividing 657 by 66, we get 9 with a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 6099.0
Deduct 594 from 657 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
66 goes into 630 9 times with a remainder of 36.
The next digit of our result is 9. 
Result so far: 6099.9
If we take 594 away from 630, we end up 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.

Let's proceed to step 8:
66 can be fit into 360 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 6099.95
Deduct 330 from 360 and we're left 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.

Let's proceed to step 9:
If we divide 300 by 66, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 6099.954
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 6099.9545
If we take 330 away from 360, 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 11:
When dividing 300 by 66, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 6099.95454
Subtract 264 from 300 to get 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 12:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 6099.954545
Deduct 330 from 360 and we're left 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 13:
66 goes into 300 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 6099.9545454
Subtracting 264 from 300 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.

Step 14:
66 goes into 360 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 6099.95454545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 6099.95454545 and a remainder of 3e-08.
