420643 divided by 36 
Let's see how many times 36 fits into 420643.

Advancing to step 1:
When dividing 4 by 36, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 36

Let's proceed to step 2:
42 divided by 36 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 36 from 42 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 36

Step 3:
If we divide 60 by 36, we get 1 and a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 36 from 60 to get 24.
Take the next digit (6) from the dividend and append it to 24, then repeat: 246 / 36

On to step 4:
The number 36 fits into 246 6 times, leaving a remainder of 30.
The next digit of our result is 6. 
Result so far: 116.0
If we take 216 away from 246, we end up with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 36

Step 5:
If we divide 304 by 36, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1168.0
If we subtract 288 from 304, we get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 36

Let's proceed to step 6:
36 can be fit into 163 4 times, resulting in a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 11684.0
Subtracting 144 from 163 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
If we divide 190 by 36, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11684.5
If we subtract 180 from 190, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 36 fits into 100 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 11684.52
Deduct 72 from 100 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
When dividing 280 by 36, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 11684.527
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
36 goes into 280 7 times with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 11684.5277
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 11684.5277 with a remainder of 0.00028.
