236668 ÷ 53 
Our goal is to divide 236668 by 53.

Step 1:
53 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 53

Going ahead to step 2:
53 goes into 23 0 times with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 53

Advancing to step 3:
When dividing 236 by 53, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 24 after subtracting 212 from 236.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 53

On to step 4:
53 goes into 246 4 times with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 212 from 246, we get 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 53

Step 5:
If we divide 346 by 53, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 446.0
If we subtract 318 from 346, we get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 53

Going ahead to step 6:
The number 53 fits into 288 5 times, leaving a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 4465.0
If we take 265 away from 288, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
230 divided by 53 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 4465.4
Subtracting 212 from 230 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
The number 53 fits into 180 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 4465.43
Subtract 159 from 180 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
53 goes into 210 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 4465.433
Subtract 159 from 210 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 4465.433, with a leftover of 0.0051.
