Let's divide 39663641 by 305
Let's see how many times 305 fits into 39663641.

Advancing to step 1:
If we divide 3 by 305, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 305

Moving on to step 2:
When dividing 39 by 305, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 305

Let's proceed to step 3:
The number 305 fits into 396 1 times, leaving a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 305 away from 396, we end up with 91.
Bring next digit (6) of the dividend behind the 91 and repeat the process: 916 / 305

Advancing to step 4:
If we divide 916 by 305, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 915 from 916 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 305

Advancing to step 5:
13 divided by 305 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 130.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 305

Advancing to step 6:
136 divided by 305 is 0 with a remainder of 136.
Record the quotient 0 as the next digit in the result. 
Result so far: 1300.0
If we take 0 away from 136, we end up with 136.
Take the next digit (4) from the dividend and append it to 136, then repeat: 1364 / 305

Let's proceed to step 7:
305 can be fit into 1364 4 times, resulting in a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 13004.0
Subtracting 1220 from 1364 leaves us with 144.
Include the next digit (1) from the dividend after 144, then repeat: 1441 / 305

Step 8:
If we divide 1441 by 305, we get 4 and a remainder of 221.
Write down 4 as next digit of the result. 
Result so far: 130044.0
If we subtract 1220 from 1441, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 9:
305 can be fit into 2210 7 times, resulting in a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 130044.7
If we subtract 2135 from 2210, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
305 can be fit into 750 2 times, resulting in a remainder of 140.
The number 2 becomes the next digit in our result. 
Result so far: 130044.72
If we subtract 610 from 750, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
1400 divided by 305 is 4 with a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 130044.724
The remainder is 180 after subtracting 1220 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
1800 divided by 305 is 5 with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 130044.7245
The remainder is 275 after subtracting 1525 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 13:
If we divide 2750 by 305, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 130044.72459
Subtracting 2745 from 2750 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
50 divided by 305 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 130044.72459
If we take 0 away from 50, we end up 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.

Let's proceed to step 15:
The number 305 fits into 500 1 times, leaving a remainder of 195.
Use 1 as the next digit of our solution. 
Result so far: 130044.7245901
Subtracting 305 from 500 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 16:
305 can be fit into 1950 6 times, resulting in a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 130044.72459016
Subtracting 1830 from 1950 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 130044.72459016 with a balance of 1.2e-07.
