We look at the division of 621093 by 43 
We want to divide 621093 by 43.

Going ahead to step 1:
43 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 43

Advancing to step 2:
43 can be fit into 62 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 43 from 62 and we're left with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 43

Going ahead to step 3:
43 can be fit into 191 4 times, resulting in a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 172 from 191 to get 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 43

Let's proceed to step 4:
When dividing 190 by 43, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 144.0
If we take 172 away from 190, we end up with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 43

On to step 5:
The number 43 fits into 189 4 times, leaving a remainder of 17.
The next digit of our result is 4. 
Result so far: 1444.0
The remainder is 17 after subtracting 172 from 189.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 43

Advancing to step 6:
If we divide 173 by 43, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 14444.0
If we take 172 away from 173, 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.

Going ahead to step 7:
43 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 14444.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 43 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 14444.02
If we take 86 away from 100, we end up 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 9:
When dividing 140 by 43, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 14444.023
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
If we divide 110 by 43, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 14444.0232
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.

On to step 11:
If we divide 240 by 43, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 14444.02325
The remainder is 25 after subtracting 215 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
43 can be fit into 250 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 14444.023255
Subtracting 215 from 250 leaves us with 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 14444.023255 and a remainder of 3.5e-06.
