We look at the division of 89403788 by 600 
We want to figure out the number of times 89403788 can be divided by 600.

On to step 1:
When dividing 8 by 600, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 600

On to step 2:
When dividing 89 by 600, we get 0 with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Grab the next digit (4) from the dividend, add it to 89, then carry on: 894 / 600

Going ahead to step 3:
600 can be fit into 894 1 times, resulting in a remainder of 294.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 294 after subtracting 600 from 894.
Bring next digit (0) of the dividend behind the 294 and repeat the process: 2940 / 600

Let's proceed to step 4:
2940 divided by 600 is 4 with a remainder of 540.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2400 from 2940, we get 540.
Include the next digit (3) from the dividend after 540, then repeat: 5403 / 600

On to step 5:
The number 600 fits into 5403 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
The remainder is 3 after subtracting 5400 from 5403.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 600

Going ahead to step 6:
If we divide 37 by 600, we get 0 and a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 1490.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 600

Let's proceed to step 7:
If we divide 378 by 600, we get 0 and a remainder of 378.
Use 0 as the next digit of our solution. 
Result so far: 14900.0
Subtracting 0 from 378 leaves us with 378.
Bring next digit (8) of the dividend behind the 378 and repeat the process: 3788 / 600

Moving on to step 8:
The number 600 fits into 3788 6 times, leaving a remainder of 188.
The next digit of our result is 6. 
Result so far: 149006.0
Subtract 3600 from 3788 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 9:
When dividing 1880 by 600, we get 3 with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 149006.3
The remainder is 80 after subtracting 1800 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
The number 600 fits into 800 1 times, leaving a remainder of 200.
The next digit of our result is 1. 
Result so far: 149006.31
Subtracting 600 from 800 leaves us 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.

On to step 11:
If we divide 2000 by 600, we get 3 and a remainder of 200.
Record the quotient 3 as the next digit in the result. 
Result so far: 149006.313
Subtracting 1800 from 2000 leaves us 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.

Moving on to step 12:
2000 divided by 600 is 3 with a remainder of 200.
The next digit of our result is 3. 
Result so far: 149006.3133
Deduct 1800 from 2000 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.

The final outcome is 149006.3133, with a leftover of 0.002.
