391218 divided by 43 
We want to divide 391218 by 43.

Step 1:
43 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 43

Going ahead to step 2:
39 divided by 43 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 43

Let's proceed to step 3:
43 goes into 391 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 4 after subtracting 387 from 391.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 43

Step 4:
42 divided by 43 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 43

Advancing to step 5:
If we divide 421 by 43, we get 9 and a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 909.0
Deduct 387 from 421 and we're left with 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 43

Step 6:
43 goes into 348 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 9098.0
The remainder is 4 after subtracting 344 from 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
40 divided by 43 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9098.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
43 can be fit into 400 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 9098.09
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
When dividing 130 by 43, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 9098.093
If we take 129 away from 130, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
If we divide 10 by 43, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9098.093
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
If we divide 100 by 43, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 9098.09302
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
43 goes into 140 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 9098.093023
Deduct 129 from 140 and we're left 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.

Step 13:
The number 43 fits into 110 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9098.0930232
If we subtract 86 from 110, we 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 14:
43 goes into 240 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 9098.09302325
Subtract 215 from 240 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 9098.09302325 with a remaining 2.5e-08.
