We're dividing 64543520 by 983 
Let's see how many times 983 fits into 64543520.

Moving on to step 1:
6 divided by 983 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 983

Let's proceed to step 2:
The number 983 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 983

Advancing to step 3:
If we divide 645 by 983, we get 0 and a remainder of 645.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 645 after subtracting 0 from 645.
Bring next digit (4) of the dividend behind the 645 and repeat the process: 6454 / 983

Moving on to step 4:
983 goes into 6454 6 times with a remainder of 556.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 5898 from 6454 and we're left with 556.
Include the next digit (3) from the dividend after 556, then repeat: 5563 / 983

On to step 5:
5563 divided by 983 is 5 with a remainder of 648.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 4915 from 5563 leaves us with 648.
Grab the next digit (5) from the dividend, add it to 648, then carry on: 6485 / 983

Moving on to step 6:
If we divide 6485 by 983, we get 6 and a remainder of 587.
The number 6 becomes the next digit in our result. 
Result so far: 656.0
Subtract 5898 from 6485 to get 587.
Append the next digit (2) from the dividend to 587 and continue with: 5872 / 983

Let's proceed to step 7:
When dividing 5872 by 983, we get 5 with a remainder of 957.
Write down 5 as next digit of the result. 
Result so far: 6565.0
If we take 4915 away from 5872, we end up with 957.
Append the next digit (0) from the dividend to 957 and continue with: 9570 / 983

On to step 8:
9570 divided by 983 is 9 with a remainder of 723.
Write down 9 as next digit of the result. 
Result so far: 65659.0
Subtract 8847 from 9570 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 9:
983 can be fit into 7230 7 times, resulting in a remainder of 349.
The number 7 becomes the next digit in our result. 
Result so far: 65659.7
Subtract 6881 from 7230 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

On to step 10:
983 goes into 3490 3 times with a remainder of 541.
Put 3 as the next digit of the answer. 
Result so far: 65659.73
If we subtract 2949 from 3490, we get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

On to step 11:
5410 divided by 983 is 5 with a remainder of 495.
Record the quotient 5 as the next digit in the result. 
Result so far: 65659.735
If we take 4915 away from 5410, we end up with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Advancing to step 12:
983 can be fit into 4950 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 65659.7355
If we take 4915 away from 4950, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 65659.7355, with a leftover of 0.00035.
