149971 divided by 43 
Let's see how many times 43 fits into 149971.

On to step 1:
43 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 43

On to step 2:
When dividing 14 by 43, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 43

Advancing to step 3:
43 goes into 149 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 129 from 149 to get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 43

Let's proceed to step 4:
43 goes into 209 4 times with a remainder of 37.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 172 from 209, we get 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 43

Step 5:
When dividing 377 by 43, we get 8 with a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 348.0
If we take 344 away from 377, we end up with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 43

Moving on to step 6:
43 goes into 331 7 times with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 3487.0
If we take 301 away from 331, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
43 can be fit into 300 6 times, resulting in a remainder of 42.
The next digit of our result is 6. 
Result so far: 3487.6
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
When dividing 420 by 43, we get 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 3487.69
Deduct 387 from 420 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
330 divided by 43 is 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 3487.697
The remainder is 29 after subtracting 301 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
If we divide 290 by 43, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 3487.6976
If we take 258 away from 290, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
320 divided by 43 is 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 3487.69767
If we take 301 away from 320, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
If we divide 190 by 43, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 3487.697674
If we subtract 172 from 190, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
When dividing 180 by 43, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 3487.6976744
Deduct 172 from 180 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 3487.6976744 with a remaining 8e-08.
