We're dividing 90241964 by 166 
Our goal is to divide 90241964 by 166.

On to step 1:
166 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 166

Going ahead to step 2:
90 divided by 166 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 166

Let's proceed to step 3:
The number 166 fits into 902 5 times, leaving a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 830 from 902 and we're left with 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 166

On to step 4:
If we divide 724 by 166, we get 4 and a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we subtract 664 from 724, we get 60.
Fetch the next digit (1) from the dividend, attach it to 60 and continue: 601 / 166

Moving on to step 5:
If we divide 601 by 166, we get 3 and a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 543.0
If we subtract 498 from 601, we get 103.
Fetch the next digit (9) from the dividend, attach it to 103 and continue: 1039 / 166

Going ahead to step 6:
166 goes into 1039 6 times with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 5436.0
The remainder is 43 after subtracting 996 from 1039.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 166

Going ahead to step 7:
166 goes into 436 2 times with a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 54362.0
Deduct 332 from 436 and we're left with 104.
Fetch the next digit (4) from the dividend, attach it to 104 and continue: 1044 / 166

Going ahead to step 8:
If we divide 1044 by 166, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 543626.0
If we take 996 away from 1044, we end up 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 9:
166 can be fit into 480 2 times, resulting in a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 543626.2
Subtract 332 from 480 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 10:
The number 166 fits into 1480 8 times, leaving a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 543626.28
Subtracting 1328 from 1480 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
166 can be fit into 1520 9 times, resulting in a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 543626.289
If we take 1494 away from 1520, 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.

On to step 12:
When dividing 260 by 166, we get 1 with a remainder of 94.
Write down 1 as next digit of the result. 
Result so far: 543626.2891
Deduct 166 from 260 and we're left 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.

Advancing to step 13:
166 can be fit into 940 5 times, resulting in a remainder of 110.
The next digit of our result is 5. 
Result so far: 543626.28915
Subtracting 830 from 940 leaves us 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 14:
The number 166 fits into 1100 6 times, leaving a remainder of 104.
The next digit of our result is 6. 
Result so far: 543626.289156
The remainder is 104 after subtracting 996 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 15:
If we divide 1040 by 166, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 543626.2891566
Subtract 996 from 1040 to get 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 result is 543626.2891566 with a remainder of 4.4e-07.
