Let's divide 309148 by 43
We want to figure out the number of times 309148 can be divided by 43.

Step 1:
If we divide 3 by 43, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 43

Advancing to step 2:
If we divide 30 by 43, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 43

Moving on to step 3:
43 can be fit into 309 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 301 from 309 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 43

On to step 4:
43 can be fit into 81 1 times, resulting in a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we take 43 away from 81, we end up with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 43

Moving on to step 5:
When dividing 384 by 43, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 718.0
Subtract 344 from 384 to get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 43

Let's proceed to step 6:
408 divided by 43 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 7189.0
Deduct 387 from 408 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.

Advancing to step 7:
If we divide 210 by 43, we get 4 and a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 7189.4
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
380 divided by 43 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 7189.48
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
360 divided by 43 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 7189.488
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 7189.488, with a leftover of 0.0016.
