45159255 ÷ 189 
Our goal is to divide 45159255 by 189.

Let's proceed to step 1:
If we divide 4 by 189, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 189

Step 2:
The number 189 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 189

On to step 3:
If we divide 451 by 189, we get 2 and a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 378 from 451 to get 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 189

On to step 4:
189 can be fit into 735 3 times, resulting in a remainder of 168.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 567 away from 735, we end up with 168.
Include the next digit (9) from the dividend after 168, then repeat: 1689 / 189

Step 5:
The number 189 fits into 1689 8 times, leaving a remainder of 177.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
Deduct 1512 from 1689 and we're left with 177.
Fetch the next digit (2) from the dividend, attach it to 177 and continue: 1772 / 189

On to step 6:
189 goes into 1772 9 times with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 2389.0
Subtracting 1701 from 1772 leaves us with 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 189

Advancing to step 7:
When dividing 715 by 189, we get 3 with a remainder of 148.
Put 3 as the next digit of the answer. 
Result so far: 23893.0
The remainder is 148 after subtracting 567 from 715.
Include the next digit (5) from the dividend after 148, then repeat: 1485 / 189

Advancing to step 8:
189 goes into 1485 7 times with a remainder of 162.
Put 7 as the next digit of the answer. 
Result so far: 238937.0
If we subtract 1323 from 1485, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 9:
The number 189 fits into 1620 8 times, leaving a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 238937.8
Deduct 1512 from 1620 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
189 can be fit into 1080 5 times, resulting in a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 238937.85
Subtracting 945 from 1080 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 11:
The number 189 fits into 1350 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 238937.857
Subtract 1323 from 1350 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
189 can be fit into 270 1 times, resulting in a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 238937.8571
Deduct 189 from 270 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 13:
810 divided by 189 is 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 238937.85714
The remainder is 54 after subtracting 756 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
The number 189 fits into 540 2 times, leaving a remainder of 162.
Record the quotient 2 as the next digit in the result. 
Result so far: 238937.857142
If we subtract 378 from 540, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 15:
The number 189 fits into 1620 8 times, leaving a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 238937.8571428
Subtracting 1512 from 1620 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 16:
When dividing 1080 by 189, we get 5 with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 238937.85714285
Deduct 945 from 1080 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Our division results in 238937.85714285 with a remaining 1.35e-07.
