We look at the division of 393596 by 43 
We want to figure out the number of times 393596 can be divided by 43.

Advancing to step 1:
3 divided by 43 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 43

On 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.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 43

Advancing to step 3:
43 goes into 393 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 387 from 393 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 43

On to step 4:
43 can be fit into 65 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 91.0
Subtracting 43 from 65 leaves us with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 43

Step 5:
When dividing 229 by 43, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 915.0
If we take 215 away from 229, we end up with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 43

Advancing to step 6:
The number 43 fits into 146 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 9153.0
Deduct 129 from 146 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
170 divided by 43 is 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 9153.3
The remainder is 41 after subtracting 129 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
43 can be fit into 410 9 times, resulting in a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 9153.39
If we take 387 away from 410, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
If we divide 230 by 43, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 9153.395
Deduct 215 from 230 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
150 divided by 43 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 9153.3953
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
43 can be fit into 210 4 times, resulting in a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 9153.39534
Subtract 172 from 210 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
43 goes into 380 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 9153.395348
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.

Step 13:
The number 43 fits into 360 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 9153.3953488
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 9153.3953488 and a remainder of 1.6e-07.
