We're dividing 45115534 by 173 
Our goal is to divide 45115534 by 173.

Advancing to step 1:
If we divide 4 by 173, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 173

Advancing to step 2:
173 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 173

Let's proceed to step 3:
The number 173 fits into 451 2 times, leaving a remainder of 105.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 346 from 451, we get 105.
Bring next digit (1) of the dividend behind the 105 and repeat the process: 1051 / 173

Step 4:
173 can be fit into 1051 6 times, resulting in a remainder of 13.
The next digit of our result is 6. 
Result so far: 26.0
If we take 1038 away from 1051, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 173

Moving on to step 5:
173 goes into 135 0 times with a remainder of 135.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
Subtracting 0 from 135 leaves us with 135.
Bring next digit (5) of the dividend behind the 135 and repeat the process: 1355 / 173

Going ahead to step 6:
The number 173 fits into 1355 7 times, leaving a remainder of 144.
Use 7 as the next digit of our solution. 
Result so far: 2607.0
If we subtract 1211 from 1355, we get 144.
Take the next digit (3) from the dividend and append it to 144, then repeat: 1443 / 173

Step 7:
When dividing 1443 by 173, we get 8 with a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 26078.0
If we take 1384 away from 1443, we end up with 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 173

Advancing to step 8:
When dividing 594 by 173, we get 3 with a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 260783.0
Subtracting 519 from 594 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
173 can be fit into 750 4 times, resulting in a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 260783.4
Subtract 692 from 750 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
When dividing 580 by 173, we get 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 260783.43
The remainder is 61 after subtracting 519 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 11:
The number 173 fits into 610 3 times, leaving a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 260783.433
Subtracting 519 from 610 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The final result is 260783.433 with a remainder of 0.0091.
