We look at the division of 30593777 by 645 
Let's see how many times 645 fits into 30593777.

Step 1:
645 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 645

On to step 2:
The number 645 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 645

Step 3:
If we divide 305 by 645, we get 0 and a remainder of 305.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 305, we get 305.
Take the next digit (9) from the dividend and append it to 305, then repeat: 3059 / 645

Step 4:
The number 645 fits into 3059 4 times, leaving a remainder of 479.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 2580 from 3059 to get 479.
Bring next digit (3) of the dividend behind the 479 and repeat the process: 4793 / 645

Going ahead to step 5:
645 can be fit into 4793 7 times, resulting in a remainder of 278.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 4515 away from 4793, we end up with 278.
Take the next digit (7) from the dividend and append it to 278, then repeat: 2787 / 645

Let's proceed to step 6:
When dividing 2787 by 645, we get 4 with a remainder of 207.
Put 4 as the next digit of the answer. 
Result so far: 474.0
If we take 2580 away from 2787, we end up with 207.
Grab the next digit (7) from the dividend, add it to 207, then carry on: 2077 / 645

Step 7:
645 can be fit into 2077 3 times, resulting in a remainder of 142.
The next digit of our result is 3. 
Result so far: 4743.0
If we take 1935 away from 2077, we end up with 142.
Fetch the next digit (7) from the dividend, attach it to 142 and continue: 1427 / 645

Let's proceed to step 8:
If we divide 1427 by 645, we get 2 and a remainder of 137.
The number 2 becomes the next digit in our result. 
Result so far: 47432.0
Subtracting 1290 from 1427 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 9:
1370 divided by 645 is 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 47432.2
The remainder is 80 after subtracting 1290 from 1370.
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 10:
If we divide 800 by 645, we get 1 and a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 47432.21
Deduct 645 from 800 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 11:
1550 divided by 645 is 2 with a remainder of 260.
The number 2 becomes the next digit in our result. 
Result so far: 47432.212
Deduct 1290 from 1550 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 12:
When dividing 2600 by 645, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 47432.2124
Subtract 2580 from 2600 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.

On to step 13:
If we divide 200 by 645, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 47432.2124
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
When dividing 2000 by 645, we get 3 with a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 47432.212403
If we take 1935 away from 2000, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 15:
When dividing 650 by 645, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 47432.2124031
The remainder is 5 after subtracting 645 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 16:
645 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 47432.2124031
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.

Our division results in 47432.2124031 with a remaining 5e-08.
