55966618 ÷ 166 
Let's see how many times 166 fits into 55966618.

Let's proceed to step 1:
When dividing 5 by 166, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 166

Step 2:
166 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 166

Advancing to step 3:
The number 166 fits into 559 3 times, leaving a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 498 from 559 leaves us with 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 166

Going ahead to step 4:
166 goes into 616 3 times with a remainder of 118.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 118 after subtracting 498 from 616.
Fetch the next digit (6) from the dividend, attach it to 118 and continue: 1186 / 166

Going ahead to step 5:
166 goes into 1186 7 times with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 337.0
If we subtract 1162 from 1186, we get 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 166

On to step 6:
166 can be fit into 246 1 times, resulting in a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 3371.0
If we take 166 away from 246, we end up with 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 166

Advancing to step 7:
If we divide 801 by 166, we get 4 and a remainder of 137.
Put 4 as the next digit of the answer. 
Result so far: 33714.0
Subtract 664 from 801 to get 137.
Take the next digit (8) from the dividend and append it to 137, then repeat: 1378 / 166

On to step 8:
166 goes into 1378 8 times with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 337148.0
The remainder is 50 after subtracting 1328 from 1378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
166 can be fit into 500 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 337148.3
Subtract 498 from 500 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
20 divided by 166 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 337148.3
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
166 goes into 200 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 337148.301
Subtracting 166 from 200 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
166 goes into 340 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 337148.3012
If we take 332 away from 340, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
80 divided by 166 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 337148.3012
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
When dividing 800 by 166, we get 4 with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 337148.301204
Subtracting 664 from 800 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 15:
166 goes into 1360 8 times with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 337148.3012048
The remainder is 32 after subtracting 1328 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 16:
320 divided by 166 is 1 with a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 337148.30120481
If we subtract 166 from 320, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 337148.30120481 with a remainder of 1.54e-07.
