We look at the division of 56603303 by 658 
Let's see how many times 658 fits into 56603303.

Step 1:
5 divided by 658 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 658

Going ahead to step 2:
The number 658 fits into 56 0 times, leaving a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Fetch the next digit (6) from the dividend, attach it to 56 and continue: 566 / 658

On to step 3:
658 can be fit into 566 0 times, resulting in a remainder of 566.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 566 leaves us with 566.
Fetch the next digit (0) from the dividend, attach it to 566 and continue: 5660 / 658

On to step 4:
5660 divided by 658 is 8 with a remainder of 396.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 396 after subtracting 5264 from 5660.
Take the next digit (3) from the dividend and append it to 396, then repeat: 3963 / 658

Advancing to step 5:
658 can be fit into 3963 6 times, resulting in a remainder of 15.
The next digit of our result is 6. 
Result so far: 86.0
Subtract 3948 from 3963 to get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 658

Advancing to step 6:
The number 658 fits into 153 0 times, leaving a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 860.0
Subtract 0 from 153 to get 153.
Take the next digit (0) from the dividend and append it to 153, then repeat: 1530 / 658

Moving on to step 7:
1530 divided by 658 is 2 with a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 8602.0
Subtracting 1316 from 1530 leaves us with 214.
Grab the next digit (3) from the dividend, add it to 214, then carry on: 2143 / 658

On to step 8:
When dividing 2143 by 658, we get 3 with a remainder of 169.
Write down 3 as next digit of the result. 
Result so far: 86023.0
Subtract 1974 from 2143 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Step 9:
658 can be fit into 1690 2 times, resulting in a remainder of 374.
Use 2 as the next digit of our solution. 
Result so far: 86023.2
Deduct 1316 from 1690 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 10:
When dividing 3740 by 658, we get 5 with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 86023.25
Deduct 3290 from 3740 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 11:
658 goes into 4500 6 times with a remainder of 552.
Put 6 as the next digit of the answer. 
Result so far: 86023.256
Subtract 3948 from 4500 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 12:
658 can be fit into 5520 8 times, resulting in a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 86023.2568
Subtracting 5264 from 5520 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 13:
658 goes into 2560 3 times with a remainder of 586.
The next digit of our result is 3. 
Result so far: 86023.25683
Subtracting 1974 from 2560 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 14:
When dividing 5860 by 658, we get 8 with a remainder of 596.
The next digit of our result is 8. 
Result so far: 86023.256838
The remainder is 596 after subtracting 5264 from 5860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 15:
5960 divided by 658 is 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 86023.2568389
If we subtract 5922 from 5960, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 16:
The number 658 fits into 380 0 times, leaving a remainder of 380.
The next digit of our result is 0. 
Result so far: 86023.2568389
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final outcome is 86023.2568389, with a leftover of 3.8e-07.
