143148 ÷ 43 
We want to divide 143148 by 43.

On to step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 43

Let's proceed to step 2:
14 divided by 43 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 43

Step 3:
43 goes into 143 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 129 from 143, we get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 43

Going ahead to step 4:
141 divided by 43 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 12 after subtracting 129 from 141.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 43

Advancing to step 5:
124 divided by 43 is 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 332.0
Subtracting 86 from 124 leaves us with 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 43

Going ahead to step 6:
43 goes into 388 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 3329.0
If we subtract 387 from 388, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 43, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3329.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 43, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 3329.02
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
The number 43 fits into 140 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3329.023
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
When dividing 110 by 43, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 3329.0232
Subtract 86 from 110 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
When dividing 240 by 43, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 3329.02325
Deduct 215 from 240 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
If we divide 250 by 43, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3329.023255
Subtract 215 from 250 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 3329.023255 and a remainder of 3.5e-06.
