49151129 ÷ 143 
We're looking to find how many times 143 goes into 49151129.

Step 1:
If we divide 4 by 143, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 143

Let's proceed to step 2:
When dividing 49 by 143, we get 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 143

Moving on to step 3:
491 divided by 143 is 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 429 from 491 to get 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 143

Advancing to step 4:
143 goes into 625 4 times with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 572 from 625 leaves us with 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 143

Let's proceed to step 5:
143 can be fit into 531 3 times, resulting in a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 343.0
Deduct 429 from 531 and we're left with 102.
Grab the next digit (1) from the dividend, add it to 102, then carry on: 1021 / 143

Going ahead to step 6:
When dividing 1021 by 143, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 3437.0
If we take 1001 away from 1021, we end up with 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 143

Going ahead to step 7:
The number 143 fits into 202 1 times, leaving a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 34371.0
If we subtract 143 from 202, we get 59.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 143

Advancing to step 8:
The number 143 fits into 599 4 times, leaving a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 343714.0
If we subtract 572 from 599, we 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.

On to step 9:
If we divide 270 by 143, we get 1 and a remainder of 127.
Put 1 as the next digit of the answer. 
Result so far: 343714.1
If we subtract 143 from 270, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 10:
1270 divided by 143 is 8 with a remainder of 126.
Use 8 as the next digit of our solution. 
Result so far: 343714.18
If we subtract 1144 from 1270, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 11:
When dividing 1260 by 143, we get 8 with a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 343714.188
Subtracting 1144 from 1260 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 343714.188 and a remainder of 0.0116.
