We look at the division of 66696610 by 389 
We want to figure out the number of times 66696610 can be divided by 389.

Advancing to step 1:
When dividing 6 by 389, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 389

Step 2:
389 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 389

On to step 3:
389 can be fit into 666 1 times, resulting in a remainder of 277.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 389 away from 666, we end up with 277.
Include the next digit (9) from the dividend after 277, then repeat: 2779 / 389

Going ahead to step 4:
389 can be fit into 2779 7 times, resulting in a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 2723 from 2779 leaves us with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 389

Advancing to step 5:
566 divided by 389 is 1 with a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Deduct 389 from 566 and we're left with 177.
Include the next digit (6) from the dividend after 177, then repeat: 1776 / 389

Advancing to step 6:
The number 389 fits into 1776 4 times, leaving a remainder of 220.
Write down 4 as next digit of the result. 
Result so far: 1714.0
Deduct 1556 from 1776 and we're left with 220.
Grab the next digit (1) from the dividend, add it to 220, then carry on: 2201 / 389

Step 7:
2201 divided by 389 is 5 with a remainder of 256.
Write down 5 as next digit of the result. 
Result so far: 17145.0
Subtract 1945 from 2201 to get 256.
Take the next digit (0) from the dividend and append it to 256, then repeat: 2560 / 389

Moving on to step 8:
When dividing 2560 by 389, we get 6 with a remainder of 226.
Put 6 as the next digit of the answer. 
Result so far: 171456.0
The remainder is 226 after subtracting 2334 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 9:
2260 divided by 389 is 5 with a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 171456.5
Subtract 1945 from 2260 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 10:
389 goes into 3150 8 times with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 171456.58
The remainder is 38 after subtracting 3112 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
When dividing 380 by 389, we get 0 with a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 171456.58
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 12:
389 goes into 3800 9 times with a remainder of 299.
Record the quotient 9 as the next digit in the result. 
Result so far: 171456.5809
If we subtract 3501 from 3800, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 13:
389 can be fit into 2990 7 times, resulting in a remainder of 267.
Write down 7 as next digit of the result. 
Result so far: 171456.58097
Subtract 2723 from 2990 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Step 14:
389 goes into 2670 6 times with a remainder of 336.
Record the quotient 6 as the next digit in the result. 
Result so far: 171456.580976
Deduct 2334 from 2670 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 15:
The number 389 fits into 3360 8 times, leaving a remainder of 248.
Write down 8 as next digit of the result. 
Result so far: 171456.5809768
Deduct 3112 from 3360 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 16:
The number 389 fits into 2480 6 times, leaving a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 171456.58097686
Subtract 2334 from 2480 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final result is 171456.58097686 with a remainder of 1.46e-07.
