58400542 ÷ 603 
We want to figure out the number of times 58400542 can be divided by 603.

Moving on to step 1:
603 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 603

Advancing to step 2:
603 can be fit into 58 0 times, resulting in a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 603

Step 3:
If we divide 584 by 603, we get 0 and a remainder of 584.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 584 leaves us with 584.
Fetch the next digit (0) from the dividend, attach it to 584 and continue: 5840 / 603

Advancing to step 4:
5840 divided by 603 is 9 with a remainder of 413.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 5427 from 5840, we get 413.
Fetch the next digit (0) from the dividend, attach it to 413 and continue: 4130 / 603

Step 5:
When dividing 4130 by 603, we get 6 with a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 96.0
The remainder is 512 after subtracting 3618 from 4130.
Include the next digit (5) from the dividend after 512, then repeat: 5125 / 603

Going ahead to step 6:
603 goes into 5125 8 times with a remainder of 301.
Put 8 as the next digit of the answer. 
Result so far: 968.0
Subtract 4824 from 5125 to get 301.
Grab the next digit (4) from the dividend, add it to 301, then carry on: 3014 / 603

Advancing to step 7:
603 goes into 3014 4 times with a remainder of 602.
Use 4 as the next digit of our solution. 
Result so far: 9684.0
Subtract 2412 from 3014 to get 602.
Append the next digit (2) from the dividend to 602 and continue with: 6022 / 603

Going ahead to step 8:
If we divide 6022 by 603, we get 9 and a remainder of 595.
The number 9 becomes the next digit in our result. 
Result so far: 96849.0
Subtract 5427 from 6022 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 9:
603 goes into 5950 9 times with a remainder of 523.
The next digit of our result is 9. 
Result so far: 96849.9
The remainder is 523 after subtracting 5427 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 10:
When dividing 5230 by 603, we get 8 with a remainder of 406.
Write down 8 as next digit of the result. 
Result so far: 96849.98
The remainder is 406 after subtracting 4824 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 11:
603 can be fit into 4060 6 times, resulting in a remainder of 442.
Use 6 as the next digit of our solution. 
Result so far: 96849.986
Subtracting 3618 from 4060 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 12:
The number 603 fits into 4420 7 times, leaving a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 96849.9867
Subtract 4221 from 4420 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 13:
If we divide 1990 by 603, we get 3 and a remainder of 181.
The next digit of our result is 3. 
Result so far: 96849.98673
If we subtract 1809 from 1990, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 14:
1810 divided by 603 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 96849.986733
The remainder is 1 after subtracting 1809 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 96849.986733, with a leftover of 1e-07.
