Going ahead to step 5:
The number 903 fits into 5963 6 times, leaving a remainder of 545.
Put 6 as the next digit of the answer. 
Result so far: 56.0
The remainder is 545 after subtracting 5418 from 5963.
Take the next digit (2) from the dividend and append it to 545, then repeat: 5452 / 903

Let's proceed to step 6:
When dividing 5452 by 903, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 566.0
If we subtract 5418 from 5452, we get 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 903

Moving on to step 7:
903 can be fit into 342 0 times, resulting in a remainder of 342.
Write down 0 as next digit of the result. 
Result so far: 5660.0
Deduct 0 from 342 and we're left with 342.
Bring next digit (9) of the dividend behind the 342 and repeat the process: 3429 / 903

Going ahead to step 8:
When dividing 3429 by 903, we get 3 with a remainder of 720.
The number 3 becomes the next digit in our result. 
Result so far: 56603.0
If we subtract 2709 from 3429, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 9:
If we divide 7200 by 903, we get 7 and a remainder of 879.
Put 7 as the next digit of the answer. 
Result so far: 56603.7
The remainder is 879 after subtracting 6321 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8790, and continue the process.

Step 10:
If we divide 8790 by 903, we get 9 and a remainder of 663.
Record the quotient 9 as the next digit in the result. 
Result so far: 56603.79
Deduct 8127 from 8790 and we're left with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Advancing to step 11:
If we divide 6630 by 903, we get 7 and a remainder of 309.
Record the quotient 7 as the next digit in the result. 
Result so far: 56603.797
The remainder is 309 after subtracting 6321 from 6630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 12:
3090 divided by 903 is 3 with a remainder of 381.
Record the quotient 3 as the next digit in the result. 
Result so far: 56603.7973
If we subtract 2709 from 3090, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Advancing to step 13:
903 can be fit into 3810 4 times, resulting in a remainder of 198.
Put 4 as the next digit of the answer. 
Result so far: 56603.79734
Subtracting 3612 from 3810 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 14:
1980 divided by 903 is 2 with a remainder of 174.
Put 2 as the next digit of the answer. 
Result so far: 56603.797342
If we subtract 1806 from 1980, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 15:
903 goes into 1740 1 times with a remainder of 837.
Use 1 as the next digit of our solution. 
Result so far: 56603.7973421
If we subtract 903 from 1740, we get 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

On to step 16:
If we divide 8370 by 903, we get 9 and a remainder of 243.
Put 9 as the next digit of the answer. 
Result so far: 56603.79734219
The remainder is 243 after subtracting 8127 from 8370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

The final outcome is 56603.79734219, with a leftover of 2.43e-07.
