Let's divide 390771 by 43
Our goal is to divide 390771 by 43.

Moving on to step 1:
43 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 43

Advancing to step 2:
39 divided by 43 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 43

Step 3:
390 divided by 43 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 387 from 390 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 43

Going ahead to step 4:
The number 43 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 90.0
Subtract 0 from 37 to get 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 43

Advancing to step 5:
If we divide 377 by 43, we get 8 and a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 908.0
If we subtract 344 from 377, we get 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 43

Going ahead to step 6:
331 divided by 43 is 7 with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 9087.0
Subtract 301 from 331 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
When dividing 300 by 43, we get 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 9087.6
Subtracting 258 from 300 leaves us 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.

Step 8:
The number 43 fits into 420 9 times, leaving a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 9087.69
If we take 387 away from 420, we end up 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.

Going ahead to step 9:
The number 43 fits into 330 7 times, leaving a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 9087.697
If we subtract 301 from 330, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
If we divide 290 by 43, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 9087.6976
Deduct 258 from 290 and we're left 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:
43 can be fit into 320 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 9087.69767
Subtract 301 from 320 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
190 divided by 43 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 9087.697674
Deduct 172 from 190 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
The number 43 fits into 180 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 9087.6976744
If we take 172 away from 180, we end up 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.

The final outcome is 9087.6976744, with a leftover of 8e-08.
