Let's divide 66397992 by 130
We want to figure out the number of times 66397992 can be divided by 130.

Going ahead to step 1:
When dividing 6 by 130, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 130

Advancing to step 2:
66 divided by 130 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 130

Advancing to step 3:
When dividing 663 by 130, we get 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 650 from 663, we get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 130

Step 4:
139 divided by 130 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 9 after subtracting 130 from 139.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 130

Advancing to step 5:
97 divided by 130 is 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 510.0
If we subtract 0 from 97, we get 97.
Include the next digit (9) from the dividend after 97, then repeat: 979 / 130

On to step 6:
130 can be fit into 979 7 times, resulting in a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 5107.0
If we take 910 away from 979, we end up with 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 130

Going ahead to step 7:
130 can be fit into 699 5 times, resulting in a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 51075.0
Subtracting 650 from 699 leaves us with 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 130

On to step 8:
130 can be fit into 492 3 times, resulting in a remainder of 102.
Use 3 as the next digit of our solution. 
Result so far: 510753.0
The remainder is 102 after subtracting 390 from 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
1020 divided by 130 is 7 with a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 510753.7
Deduct 910 from 1020 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
When dividing 1100 by 130, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 510753.78
Subtract 1040 from 1100 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
130 can be fit into 600 4 times, resulting in a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 510753.784
Subtract 520 from 600 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
The number 130 fits into 800 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 510753.7846
Subtract 780 from 800 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
The number 130 fits into 200 1 times, leaving a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 510753.78461
Deduct 130 from 200 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
700 divided by 130 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 510753.784615
Subtracting 650 from 700 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 15:
When dividing 500 by 130, we get 3 with a remainder of 110.
Record the quotient 3 as the next digit in the result. 
Result so far: 510753.7846153
If we subtract 390 from 500, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 16:
130 can be fit into 1100 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 510753.78461538
If we take 1040 away from 1100, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 510753.78461538 with a remainder of 6e-08.
