We're dividing 85963439 by 600 
We're looking to find how many times 600 goes into 85963439.

Moving on to step 1:
The number 600 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 600

Going ahead to step 2:
600 goes into 85 0 times with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 600

On to step 3:
If we divide 859 by 600, we get 1 and a remainder of 259.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 600 from 859, we get 259.
Include the next digit (6) from the dividend after 259, then repeat: 2596 / 600

On to step 4:
2596 divided by 600 is 4 with a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 2400 from 2596 to get 196.
Grab the next digit (3) from the dividend, add it to 196, then carry on: 1963 / 600

Step 5:
If we divide 1963 by 600, we get 3 and a remainder of 163.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Subtracting 1800 from 1963 leaves us with 163.
Bring next digit (4) of the dividend behind the 163 and repeat the process: 1634 / 600

On to step 6:
When dividing 1634 by 600, we get 2 with a remainder of 434.
The next digit of our result is 2. 
Result so far: 1432.0
Deduct 1200 from 1634 and we're left with 434.
Take the next digit (3) from the dividend and append it to 434, then repeat: 4343 / 600

Moving on to step 7:
600 goes into 4343 7 times with a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 14327.0
The remainder is 143 after subtracting 4200 from 4343.
Fetch the next digit (9) from the dividend, attach it to 143 and continue: 1439 / 600

Moving on to step 8:
1439 divided by 600 is 2 with a remainder of 239.
Use 2 as the next digit of our solution. 
Result so far: 143272.0
Deduct 1200 from 1439 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 9:
When dividing 2390 by 600, we get 3 with a remainder of 590.
Put 3 as the next digit of the answer. 
Result so far: 143272.3
Deduct 1800 from 2390 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 10:
600 can be fit into 5900 9 times, resulting in a remainder of 500.
The number 9 becomes the next digit in our result. 
Result so far: 143272.39
Subtracting 5400 from 5900 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 11:
The number 600 fits into 5000 8 times, leaving a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 143272.398
The remainder is 200 after subtracting 4800 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
The number 600 fits into 2000 3 times, leaving a remainder of 200.
Record the quotient 3 as the next digit in the result. 
Result so far: 143272.3983
If we subtract 1800 from 2000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
When dividing 2000 by 600, we get 3 with a remainder of 200.
Record the quotient 3 as the next digit in the result. 
Result so far: 143272.39833
The remainder is 200 after subtracting 1800 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 143272.39833 with a remaining 0.0002.
