We're dividing 65552596 by 166 
We want to figure out the number of times 65552596 can be divided by 166.

Advancing to step 1:
166 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 166

On to step 2:
If we divide 65 by 166, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 166

Going ahead to step 3:
If we divide 655 by 166, we get 3 and a remainder of 157.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 157 after subtracting 498 from 655.
Take the next digit (5) from the dividend and append it to 157, then repeat: 1575 / 166

On to step 4:
1575 divided by 166 is 9 with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 81 after subtracting 1494 from 1575.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 166

On to step 5:
812 divided by 166 is 4 with a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 394.0
Deduct 664 from 812 and we're left with 148.
Grab the next digit (5) from the dividend, add it to 148, then carry on: 1485 / 166

On to step 6:
1485 divided by 166 is 8 with a remainder of 157.
The next digit of our result is 8. 
Result so far: 3948.0
The remainder is 157 after subtracting 1328 from 1485.
Fetch the next digit (9) from the dividend, attach it to 157 and continue: 1579 / 166

Step 7:
The number 166 fits into 1579 9 times, leaving a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 39489.0
If we subtract 1494 from 1579, we get 85.
Grab the next digit (6) from the dividend, add it to 85, then carry on: 856 / 166

Let's proceed to step 8:
166 goes into 856 5 times with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 394895.0
If we take 830 away from 856, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
The number 166 fits into 260 1 times, leaving a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 394895.1
If we take 166 away from 260, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 10:
166 goes into 940 5 times with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 394895.15
Deduct 830 from 940 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 11:
166 goes into 1100 6 times with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 394895.156
If we take 996 away from 1100, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 12:
When dividing 1040 by 166, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 394895.1566
Deduct 996 from 1040 and we're left 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.

The final outcome is 394895.1566, with a leftover of 0.00044.
