5581483 ÷ 143 
We want to divide 5581483 by 143.

On to step 1:
When dividing 5 by 143, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 143

Moving on to step 2:
55 divided by 143 is 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 143

Moving on to step 3:
558 divided by 143 is 3 with a remainder of 129.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 429 away from 558, we end up with 129.
Grab the next digit (1) from the dividend, add it to 129, then carry on: 1291 / 143

Moving on to step 4:
143 goes into 1291 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 1287 from 1291, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 143

Moving on to step 5:
If we divide 44 by 143, we get 0 and a remainder of 44.
The next digit of our result is 0. 
Result so far: 390.0
Subtract 0 from 44 to get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 143

Advancing to step 6:
The number 143 fits into 448 3 times, leaving a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 3903.0
The remainder is 19 after subtracting 429 from 448.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 143

On to step 7:
143 goes into 193 1 times with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 39031.0
Subtracting 143 from 193 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
The number 143 fits into 500 3 times, leaving a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 39031.3
Subtract 429 from 500 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
143 goes into 710 4 times with a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 39031.34
If we subtract 572 from 710, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 10:
The number 143 fits into 1380 9 times, leaving a remainder of 93.
Write down 9 as next digit of the result. 
Result so far: 39031.349
The remainder is 93 after subtracting 1287 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 11:
930 divided by 143 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 39031.3496
Deduct 858 from 930 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
If we divide 720 by 143, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 39031.34965
If we subtract 715 from 720, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
50 divided by 143 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 39031.34965
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
When dividing 500 by 143, we get 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 39031.3496503
Subtract 429 from 500 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 15:
The number 143 fits into 710 4 times, leaving a remainder of 138.
Use 4 as the next digit of our solution. 
Result so far: 39031.34965034
If we take 572 away from 710, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 39031.34965034 with a remainder of 1.38e-07.
