We're dividing 623638 by 43 
We want to divide 623638 by 43.

Step 1:
43 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 43

Let's proceed to step 2:
The number 43 fits into 62 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 43 from 62 to get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 43

Going ahead to step 3:
193 divided by 43 is 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 172 from 193, we get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 43

Advancing to step 4:
216 divided by 43 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 145.0
Subtracting 215 from 216 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 43

Step 5:
13 divided by 43 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 1450.0
Subtract 0 from 13 to get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 43

Step 6:
If we divide 138 by 43, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 14503.0
Deduct 129 from 138 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 43 fits into 90 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 14503.2
Subtract 86 from 90 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 43, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 14503.2
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
43 goes into 400 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 14503.209
Subtracting 387 from 400 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
When dividing 130 by 43, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 14503.2093
The remainder is 1 after subtracting 129 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
43 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 14503.2093
If we take 0 away from 10, we end up 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.

Going ahead to step 12:
If we divide 100 by 43, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 14503.209302
Subtracting 86 from 100 leaves us 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.

Going ahead to step 13:
When dividing 140 by 43, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 14503.2093023
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.

Advancing to step 14:
If we divide 110 by 43, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 14503.20930232
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 14503.20930232, with a leftover of 2.4e-08.
