79081209 ÷ 166 
Let's see how many times 166 fits into 79081209.

Going ahead to step 1:
7 divided by 166 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 166

Moving on to step 2:
79 divided by 166 is 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 166

On to step 3:
166 goes into 790 4 times with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 664 from 790 to get 126.
Bring next digit (8) of the dividend behind the 126 and repeat the process: 1268 / 166

Going ahead to step 4:
The number 166 fits into 1268 7 times, leaving a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 1162 from 1268 to get 106.
Bring next digit (1) of the dividend behind the 106 and repeat the process: 1061 / 166

Moving on to step 5:
166 can be fit into 1061 6 times, resulting in a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 476.0
Deduct 996 from 1061 and we're left with 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 166

Going ahead to step 6:
When dividing 652 by 166, we get 3 with a remainder of 154.
The next digit of our result is 3. 
Result so far: 4763.0
If we subtract 498 from 652, we get 154.
Append the next digit (0) from the dividend to 154 and continue with: 1540 / 166

Step 7:
166 goes into 1540 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 47639.0
Subtracting 1494 from 1540 leaves us with 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 166

Step 8:
469 divided by 166 is 2 with a remainder of 137.
Write down 2 as next digit of the result. 
Result so far: 476392.0
The remainder is 137 after subtracting 332 from 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 9:
1370 divided by 166 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 476392.8
Subtracting 1328 from 1370 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
If we divide 420 by 166, we get 2 and a remainder of 88.
The next digit of our result is 2. 
Result so far: 476392.82
If we subtract 332 from 420, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
The number 166 fits into 880 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 476392.825
If we subtract 830 from 880, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
When dividing 500 by 166, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 476392.8253
Subtracting 498 from 500 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
20 divided by 166 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 476392.8253
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
166 goes into 200 1 times with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 476392.825301
Subtract 166 from 200 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 15:
If we divide 340 by 166, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 476392.8253012
Subtract 332 from 340 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 16:
80 divided by 166 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 476392.8253012
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 476392.8253012 with a balance of 8e-08.
