55521419 ÷ 166 
Let's see how many times 166 fits into 55521419.

Moving on to step 1:
166 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 166

On to step 2:
The number 166 fits into 55 0 times, leaving a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 166

Let's proceed to step 3:
555 divided by 166 is 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 498 from 555 and we're left with 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 166

Step 4:
166 can be fit into 572 3 times, resulting in a remainder of 74.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtract 498 from 572 to get 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 166

On to step 5:
If we divide 741 by 166, we get 4 and a remainder of 77.
The next digit of our result is 4. 
Result so far: 334.0
If we subtract 664 from 741, we get 77.
Take the next digit (4) from the dividend and append it to 77, then repeat: 774 / 166

On to step 6:
166 goes into 774 4 times with a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 3344.0
The remainder is 110 after subtracting 664 from 774.
Bring next digit (1) of the dividend behind the 110 and repeat the process: 1101 / 166

Advancing to step 7:
If we divide 1101 by 166, we get 6 and a remainder of 105.
Record the quotient 6 as the next digit in the result. 
Result so far: 33446.0
If we take 996 away from 1101, we end up with 105.
Include the next digit (9) from the dividend after 105, then repeat: 1059 / 166

Let's proceed to step 8:
1059 divided by 166 is 6 with a remainder of 63.
Record the quotient 6 as the next digit in the result. 
Result so far: 334466.0
The remainder is 63 after subtracting 996 from 1059.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
630 divided by 166 is 3 with a remainder of 132.
Record the quotient 3 as the next digit in the result. 
Result so far: 334466.3
Subtracting 498 from 630 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 10:
1320 divided by 166 is 7 with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 334466.37
The remainder is 158 after subtracting 1162 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 11:
166 can be fit into 1580 9 times, resulting in a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 334466.379
Deduct 1494 from 1580 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 12:
The number 166 fits into 860 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 334466.3795
Deduct 830 from 860 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
The number 166 fits into 300 1 times, leaving a remainder of 134.
Record the quotient 1 as the next digit in the result. 
Result so far: 334466.37951
If we take 166 away from 300, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 14:
If we divide 1340 by 166, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 334466.379518
If we subtract 1328 from 1340, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
120 divided by 166 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 334466.379518
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 16:
If we divide 1200 by 166, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 334466.37951807
The remainder is 38 after subtracting 1162 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 334466.37951807 with a balance of 3.8e-08.
