We look at the division of 60308031 by 640 
Let's see how many times 640 fits into 60308031.

Step 1:
640 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 640

Moving on to step 2:
60 divided by 640 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 640

Step 3:
640 goes into 603 0 times with a remainder of 603.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 603 leaves us with 603.
Fetch the next digit (0) from the dividend, attach it to 603 and continue: 6030 / 640

Step 4:
6030 divided by 640 is 9 with a remainder of 270.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 5760 from 6030, we get 270.
Take the next digit (8) from the dividend and append it to 270, then repeat: 2708 / 640

Going ahead to step 5:
The number 640 fits into 2708 4 times, leaving a remainder of 148.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 2560 away from 2708, we end up with 148.
Take the next digit (0) from the dividend and append it to 148, then repeat: 1480 / 640

On to step 6:
640 goes into 1480 2 times with a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 942.0
If we take 1280 away from 1480, we end up with 200.
Include the next digit (3) from the dividend after 200, then repeat: 2003 / 640

Advancing to step 7:
If we divide 2003 by 640, we get 3 and a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 9423.0
If we take 1920 away from 2003, we end up with 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 640

Let's proceed to step 8:
If we divide 831 by 640, we get 1 and a remainder of 191.
The next digit of our result is 1. 
Result so far: 94231.0
If we take 640 away from 831, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 9:
640 can be fit into 1910 2 times, resulting in a remainder of 630.
Write down 2 as next digit of the result. 
Result so far: 94231.2
If we subtract 1280 from 1910, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 10:
640 goes into 6300 9 times with a remainder of 540.
The number 9 becomes the next digit in our result. 
Result so far: 94231.29
If we subtract 5760 from 6300, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 11:
640 can be fit into 5400 8 times, resulting in a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 94231.298
If we take 5120 away from 5400, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
If we divide 2800 by 640, we get 4 and a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 94231.2984
If we take 2560 away from 2800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
640 can be fit into 2400 3 times, resulting in a remainder of 480.
Write down 3 as next digit of the result. 
Result so far: 94231.29843
If we take 1920 away from 2400, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 14:
640 goes into 4800 7 times with a remainder of 320.
Use 7 as the next digit of our solution. 
Result so far: 94231.298437
If we subtract 4480 from 4800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 94231.2984375
If we take 3200 away from 3200, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 16:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 94231.2984375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 94231.2984375 and a remainder of 0.0.
