3583799 ÷ 143 
We want to figure out the number of times 3583799 can be divided by 143.

Advancing to step 1:
If we divide 3 by 143, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 143

On to step 2:
143 goes into 35 0 times with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 143

On to step 3:
143 can be fit into 358 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 286 away from 358, we end up with 72.
Fetch the next digit (3) from the dividend, attach it to 72 and continue: 723 / 143

Step 4:
723 divided by 143 is 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 715 from 723 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 143

Moving on to step 5:
143 goes into 87 0 times with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 250.0
Subtract 0 from 87 to get 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 143

Let's proceed to step 6:
879 divided by 143 is 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 2506.0
Subtract 858 from 879 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 143

Going ahead to step 7:
The number 143 fits into 219 1 times, leaving a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 25061.0
If we take 143 away from 219, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 8:
If we divide 760 by 143, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 25061.5
The remainder is 45 after subtracting 715 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
143 can be fit into 450 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 25061.53
Deduct 429 from 450 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
210 divided by 143 is 1 with a remainder of 67.
The next digit of our result is 1. 
Result so far: 25061.531
The remainder is 67 after subtracting 143 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 11:
When dividing 670 by 143, we get 4 with a remainder of 98.
Record the quotient 4 as the next digit in the result. 
Result so far: 25061.5314
Deduct 572 from 670 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 12:
143 goes into 980 6 times with a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 25061.53146
Deduct 858 from 980 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 13:
If we divide 1220 by 143, we get 8 and a remainder of 76.
The next digit of our result is 8. 
Result so far: 25061.531468
If we subtract 1144 from 1220, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
143 goes into 760 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 25061.5314685
Subtract 715 from 760 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 15:
If we divide 450 by 143, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 25061.53146853
If we take 429 away from 450, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 25061.53146853 with a remaining 2.1e-08.
