We look at the division of 66257620 by 385 
Let's see how many times 385 fits into 66257620.

Let's proceed to step 1:
When dividing 6 by 385, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 385

Moving on to step 2:
If we divide 66 by 385, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 385

Step 3:
662 divided by 385 is 1 with a remainder of 277.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 385 from 662 and we're left with 277.
Take the next digit (5) from the dividend and append it to 277, then repeat: 2775 / 385

Going ahead to step 4:
If we divide 2775 by 385, we get 7 and a remainder of 80.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 80 after subtracting 2695 from 2775.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 385

On to step 5:
If we divide 807 by 385, we get 2 and a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 172.0
The remainder is 37 after subtracting 770 from 807.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 385

Advancing to step 6:
376 divided by 385 is 0 with a remainder of 376.
Put 0 as the next digit of the answer. 
Result so far: 1720.0
Subtracting 0 from 376 leaves us with 376.
Take the next digit (2) from the dividend and append it to 376, then repeat: 3762 / 385

Step 7:
385 can be fit into 3762 9 times, resulting in a remainder of 297.
Use 9 as the next digit of our solution. 
Result so far: 17209.0
Deduct 3465 from 3762 and we're left with 297.
Fetch the next digit (0) from the dividend, attach it to 297 and continue: 2970 / 385

Moving on to step 8:
385 can be fit into 2970 7 times, resulting in a remainder of 275.
The number 7 becomes the next digit in our result. 
Result so far: 172097.0
Subtract 2695 from 2970 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 9:
385 can be fit into 2750 7 times, resulting in a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 172097.7
Deduct 2695 from 2750 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
The number 385 fits into 550 1 times, leaving a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 172097.71
Deduct 385 from 550 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 11:
385 can be fit into 1650 4 times, resulting in a remainder of 110.
Use 4 as the next digit of our solution. 
Result so far: 172097.714
The remainder is 110 after subtracting 1540 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 12:
1100 divided by 385 is 2 with a remainder of 330.
The next digit of our result is 2. 
Result so far: 172097.7142
Deduct 770 from 1100 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 13:
3300 divided by 385 is 8 with a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 172097.71428
If we subtract 3080 from 3300, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 14:
The number 385 fits into 2200 5 times, leaving a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 172097.714285
Subtracting 1925 from 2200 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 15:
When dividing 2750 by 385, we get 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 172097.7142857
If we subtract 2695 from 2750, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 16:
550 divided by 385 is 1 with a remainder of 165.
Put 1 as the next digit of the answer. 
Result so far: 172097.71428571
Deduct 385 from 550 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

In conclusion, the division gives 172097.71428571 with a balance of 1.65e-07.
