We look at the division of 66505274 by 436 
We want to divide 66505274 by 436.

Advancing to step 1:
6 divided by 436 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 436

Going ahead to 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
If we take 0 away from 66, we end up with 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 436

Going ahead to step 3:
If we divide 665 by 436, we get 1 and a remainder of 229.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 436 from 665 to get 229.
Include the next digit (0) from the dividend after 229, then repeat: 2290 / 436

On to step 4:
If we divide 2290 by 436, we get 5 and a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 110 after subtracting 2180 from 2290.
Take the next digit (5) from the dividend and append it to 110, then repeat: 1105 / 436

Let's proceed to step 5:
1105 divided by 436 is 2 with a remainder of 233.
The next digit of our result is 2. 
Result so far: 152.0
If we take 872 away from 1105, we end up with 233.
Grab the next digit (2) from the dividend, add it to 233, then carry on: 2332 / 436

Going ahead to step 6:
The number 436 fits into 2332 5 times, leaving a remainder of 152.
Record the quotient 5 as the next digit in the result. 
Result so far: 1525.0
Subtracting 2180 from 2332 leaves us with 152.
Bring next digit (7) of the dividend behind the 152 and repeat the process: 1527 / 436

Going ahead to step 7:
If we divide 1527 by 436, we get 3 and a remainder of 219.
Record the quotient 3 as the next digit in the result. 
Result so far: 15253.0
If we take 1308 away from 1527, we end up with 219.
Append the next digit (4) from the dividend to 219 and continue with: 2194 / 436

Step 8:
436 can be fit into 2194 5 times, resulting in a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 152535.0
Subtract 2180 from 2194 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
If we divide 140 by 436, we get 0 and a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 152535.0
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
If we divide 1400 by 436, we get 3 and a remainder of 92.
The number 3 becomes the next digit in our result. 
Result so far: 152535.03
Deduct 1308 from 1400 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 11:
436 can be fit into 920 2 times, resulting in a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 152535.032
Subtracting 872 from 920 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
The number 436 fits into 480 1 times, leaving a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 152535.0321
If we take 436 away from 480, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
436 can be fit into 440 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 152535.03211
Subtracting 436 from 440 leaves us 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.

Our division results in 152535.03211 with a remaining 4e-06.
