We look at the division of 66668263 by 436 
We're looking to find how many times 436 goes into 66668263.

On to step 1:
436 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 436

Step 2:
When dividing 66 by 436, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 436

On to step 3:
436 can be fit into 666 1 times, resulting in a remainder of 230.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 436 from 666 leaves us with 230.
Grab the next digit (6) from the dividend, add it to 230, then carry on: 2306 / 436

Going ahead to step 4:
If we divide 2306 by 436, we get 5 and a remainder of 126.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2180 from 2306 to get 126.
Append the next digit (8) from the dividend to 126 and continue with: 1268 / 436

Going ahead to step 5:
When dividing 1268 by 436, we get 2 with a remainder of 396.
Write down 2 as next digit of the result. 
Result so far: 152.0
The remainder is 396 after subtracting 872 from 1268.
Grab the next digit (2) from the dividend, add it to 396, then carry on: 3962 / 436

Step 6:
When dividing 3962 by 436, we get 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 1529.0
Subtract 3924 from 3962 to get 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 436

Let's proceed to step 7:
386 divided by 436 is 0 with a remainder of 386.
Put 0 as the next digit of the answer. 
Result so far: 15290.0
Deduct 0 from 386 and we're left with 386.
Fetch the next digit (3) from the dividend, attach it to 386 and continue: 3863 / 436

Going ahead to step 8:
3863 divided by 436 is 8 with a remainder of 375.
The next digit of our result is 8. 
Result so far: 152908.0
If we take 3488 away from 3863, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 9:
When dividing 3750 by 436, we get 8 with a remainder of 262.
Put 8 as the next digit of the answer. 
Result so far: 152908.8
Deduct 3488 from 3750 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 10:
When dividing 2620 by 436, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 152908.86
If we take 2616 away from 2620, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
436 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 152908.86
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
436 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 152908.86
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 152908.86 with a remainder of 0.004.
