We divide 66376669 by 389
We want to divide 66376669 by 389.

Advancing to step 1:
If we divide 6 by 389, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 389

Advancing to step 2:
389 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 389

Advancing to step 3:
389 can be fit into 663 1 times, resulting in a remainder of 274.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 274 after subtracting 389 from 663.
Append the next digit (7) from the dividend to 274 and continue with: 2747 / 389

Let's proceed to step 4:
The number 389 fits into 2747 7 times, leaving a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 2723 from 2747 leaves us with 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 389

Advancing to step 5:
389 can be fit into 246 0 times, resulting in a remainder of 246.
The next digit of our result is 0. 
Result so far: 170.0
Deduct 0 from 246 and we're left with 246.
Append the next digit (6) from the dividend to 246 and continue with: 2466 / 389

Step 6:
389 can be fit into 2466 6 times, resulting in a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 1706.0
If we subtract 2334 from 2466, we get 132.
Fetch the next digit (6) from the dividend, attach it to 132 and continue: 1326 / 389

On to step 7:
389 can be fit into 1326 3 times, resulting in a remainder of 159.
The number 3 becomes the next digit in our result. 
Result so far: 17063.0
If we subtract 1167 from 1326, we get 159.
Grab the next digit (9) from the dividend, add it to 159, then carry on: 1599 / 389

Step 8:
389 can be fit into 1599 4 times, resulting in a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 170634.0
Subtracting 1556 from 1599 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
389 can be fit into 430 1 times, resulting in a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 170634.1
Deduct 389 from 430 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
389 can be fit into 410 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 170634.11
Subtract 389 from 410 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 170634.11 with a remainder of 0.021.
