We're dividing 89603103 by 574 
Our goal is to divide 89603103 by 574.

Going ahead to step 1:
8 divided by 574 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 574

Step 2:
89 divided by 574 is 0 with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 574

Advancing to step 3:
When dividing 896 by 574, we get 1 with a remainder of 322.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 322 after subtracting 574 from 896.
Take the next digit (0) from the dividend and append it to 322, then repeat: 3220 / 574

On to step 4:
3220 divided by 574 is 5 with a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 2870 from 3220 leaves us with 350.
Grab the next digit (3) from the dividend, add it to 350, then carry on: 3503 / 574

Advancing to step 5:
The number 574 fits into 3503 6 times, leaving a remainder of 59.
Write down 6 as next digit of the result. 
Result so far: 156.0
Subtracting 3444 from 3503 leaves us with 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 574

Let's proceed to step 6:
591 divided by 574 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1561.0
If we subtract 574 from 591, we get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 574

Moving on to step 7:
The number 574 fits into 170 0 times, leaving a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 15610.0
If we take 0 away from 170, we end up with 170.
Take the next digit (3) from the dividend and append it to 170, then repeat: 1703 / 574

Step 8:
1703 divided by 574 is 2 with a remainder of 555.
Put 2 as the next digit of the answer. 
Result so far: 156102.0
If we subtract 1148 from 1703, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 9:
When dividing 5550 by 574, we get 9 with a remainder of 384.
Write down 9 as next digit of the result. 
Result so far: 156102.9
Deduct 5166 from 5550 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 10:
574 can be fit into 3840 6 times, resulting in a remainder of 396.
Use 6 as the next digit of our solution. 
Result so far: 156102.96
The remainder is 396 after subtracting 3444 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 11:
The number 574 fits into 3960 6 times, leaving a remainder of 516.
The next digit of our result is 6. 
Result so far: 156102.966
Subtract 3444 from 3960 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

After the division, we end up with 156102.966 and a remainder of 0.0516.
