643164 ÷ 36 
We want to figure out the number of times 643164 can be divided by 36.

Step 1:
If we divide 6 by 36, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 36

Moving on to step 2:
64 divided by 36 is 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 28 after subtracting 36 from 64.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 36

Advancing to step 3:
36 goes into 283 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 252 away from 283, we end up with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 36

Step 4:
311 divided by 36 is 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 178.0
The remainder is 23 after subtracting 288 from 311.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 36

Moving on to step 5:
36 goes into 236 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 1786.0
Subtracting 216 from 236 leaves us with 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 36

Moving on to step 6:
When dividing 204 by 36, we get 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 17865.0
Subtract 180 from 204 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 7:
240 divided by 36 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 17865.6
Deduct 216 from 240 and we're left 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.

Advancing to step 8:
When dividing 240 by 36, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 17865.66
Deduct 216 from 240 and we're left 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.

After the division, we end up with 17865.66 and a remainder of 0.024.
