636420 divided by 43 
We want to figure out the number of times 636420 can be divided by 43.

Let's proceed to step 1:
The number 43 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 43

On to step 2:
If we divide 63 by 43, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 43 from 63 and we're left with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 43

Let's proceed to step 3:
43 can be fit into 206 4 times, resulting in a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 172 from 206 leaves us with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 43

On to step 4:
43 can be fit into 344 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 148.0
Deduct 344 from 344 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 43

On to step 5:
If we divide 2 by 43, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 1480.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 43

Advancing to step 6:
When dividing 20 by 43, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 14800.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
If we divide 200 by 43, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 14800.4
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
280 divided by 43 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 14800.46
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
43 goes into 220 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 14800.465
Subtracting 215 from 220 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
When dividing 50 by 43, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 14800.4651
Deduct 43 from 50 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
43 can be fit into 70 1 times, resulting in a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 14800.46511
Deduct 43 from 70 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 14800.46511, with a leftover of 2.7e-05.
