Let's divide 397893 by 43
We want to figure out the number of times 397893 can be divided by 43.

On to step 1:
3 divided by 43 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 43

Moving on to step 2:
39 divided by 43 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 43

On to step 3:
When dividing 397 by 43, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 387 from 397 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 43

Step 4:
43 can be fit into 108 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtracting 86 from 108 leaves us with 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 43

Going ahead to step 5:
229 divided by 43 is 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 925.0
If we take 215 away from 229, we end up with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 43

Advancing to step 6:
43 can be fit into 143 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 9253.0
If we subtract 129 from 143, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 9253.3
Subtracting 129 from 140 leaves us 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.

Moving on to step 8:
The number 43 fits into 110 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 9253.32
Subtract 86 from 110 to 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.

On to step 9:
If we divide 240 by 43, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9253.325
Deduct 215 from 240 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
250 divided by 43 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 9253.3255
If we subtract 215 from 250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 9253.3255 and a remainder of 0.00035.
