We look at the division of 81458471 by 600 
We're looking to find how many times 600 goes into 81458471.

On to step 1:
The number 600 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 600

Advancing to step 2:
The number 600 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 600

Step 3:
The number 600 fits into 814 1 times, leaving a remainder of 214.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 600 from 814, we get 214.
Bring next digit (5) of the dividend behind the 214 and repeat the process: 2145 / 600

Let's proceed to step 4:
600 goes into 2145 3 times with a remainder of 345.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1800 away from 2145, we end up with 345.
Fetch the next digit (8) from the dividend, attach it to 345 and continue: 3458 / 600

On to step 5:
The number 600 fits into 3458 5 times, leaving a remainder of 458.
The next digit of our result is 5. 
Result so far: 135.0
Subtracting 3000 from 3458 leaves us with 458.
Append the next digit (4) from the dividend to 458 and continue with: 4584 / 600

Going ahead to step 6:
If we divide 4584 by 600, we get 7 and a remainder of 384.
The number 7 becomes the next digit in our result. 
Result so far: 1357.0
Subtracting 4200 from 4584 leaves us with 384.
Take the next digit (7) from the dividend and append it to 384, then repeat: 3847 / 600

Advancing to step 7:
600 goes into 3847 6 times with a remainder of 247.
Use 6 as the next digit of our solution. 
Result so far: 13576.0
If we take 3600 away from 3847, we end up with 247.
Append the next digit (1) from the dividend to 247 and continue with: 2471 / 600

On to step 8:
2471 divided by 600 is 4 with a remainder of 71.
Write down 4 as next digit of the result. 
Result so far: 135764.0
Subtract 2400 from 2471 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
If we divide 710 by 600, we get 1 and a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 135764.1
If we subtract 600 from 710, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
The number 600 fits into 1100 1 times, leaving a remainder of 500.
Record the quotient 1 as the next digit in the result. 
Result so far: 135764.11
Subtracting 600 from 1100 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.

The quotient of the division is 135764.11, and the remainder is 0.5.
