We look at the division of 73108903 by 558 
We want to divide 73108903 by 558.

Step 1:
558 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 558

Step 2:
The number 558 fits into 73 0 times, leaving a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 558

Going ahead to step 3:
When dividing 731 by 558, we get 1 with a remainder of 173.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 558 from 731 and we're left with 173.
Append the next digit (0) from the dividend to 173 and continue with: 1730 / 558

Step 4:
If we divide 1730 by 558, we get 3 and a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1674 away from 1730, we end up with 56.
Include the next digit (8) from the dividend after 56, then repeat: 568 / 558

Moving on to step 5:
When dividing 568 by 558, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 131.0
If we subtract 558 from 568, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 558

Advancing to step 6:
109 divided by 558 is 0 with a remainder of 109.
Write down 0 as next digit of the result. 
Result so far: 1310.0
If we subtract 0 from 109, we get 109.
Grab the next digit (0) from the dividend, add it to 109, then carry on: 1090 / 558

Step 7:
If we divide 1090 by 558, we get 1 and a remainder of 532.
Write down 1 as next digit of the result. 
Result so far: 13101.0
Subtracting 558 from 1090 leaves us with 532.
Fetch the next digit (3) from the dividend, attach it to 532 and continue: 5323 / 558

On to step 8:
558 can be fit into 5323 9 times, resulting in a remainder of 301.
Use 9 as the next digit of our solution. 
Result so far: 131019.0
The remainder is 301 after subtracting 5022 from 5323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 9:
The number 558 fits into 3010 5 times, leaving a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 131019.5
Deduct 2790 from 3010 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
The number 558 fits into 2200 3 times, leaving a remainder of 526.
Use 3 as the next digit of our solution. 
Result so far: 131019.53
Subtract 1674 from 2200 to get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 11:
When dividing 5260 by 558, we get 9 with a remainder of 238.
The next digit of our result is 9. 
Result so far: 131019.539
The remainder is 238 after subtracting 5022 from 5260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 12:
The number 558 fits into 2380 4 times, leaving a remainder of 148.
Record the quotient 4 as the next digit in the result. 
Result so far: 131019.5394
Deduct 2232 from 2380 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 13:
When dividing 1480 by 558, we get 2 with a remainder of 364.
Put 2 as the next digit of the answer. 
Result so far: 131019.53942
Subtracting 1116 from 1480 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 14:
The number 558 fits into 3640 6 times, leaving a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 131019.539426
Deduct 3348 from 3640 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 15:
The number 558 fits into 2920 5 times, leaving a remainder of 130.
The next digit of our result is 5. 
Result so far: 131019.5394265
If we subtract 2790 from 2920, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 16:
When dividing 1300 by 558, we get 2 with a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 131019.53942652
The remainder is 184 after subtracting 1116 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final result is 131019.53942652 with a remainder of 1.84e-07.
