166166 divided by 79 
Let's see how many times 79 fits into 166166.

On to step 1:
The number 79 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 79

On to step 2:
16 divided by 79 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 79

Step 3:
79 can be fit into 166 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 158 from 166 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 79

Going ahead to step 4:
When dividing 81 by 79, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 79 from 81 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 79

On to step 5:
When dividing 26 by 79, we get 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 210.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 79

Going ahead to step 6:
When dividing 266 by 79, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 2103.0
If we take 237 away from 266, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
290 divided by 79 is 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 2103.3
Deduct 237 from 290 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 8:
79 can be fit into 530 6 times, resulting in a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 2103.36
If we take 474 away from 530, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
If we divide 560 by 79, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 2103.367
If we take 553 away from 560, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
If we divide 70 by 79, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 2103.367
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
When dividing 700 by 79, we get 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 2103.36708
Deduct 632 from 700 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
79 can be fit into 680 8 times, resulting in a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 2103.367088
If we take 632 away from 680, 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.

The final outcome is 2103.367088, with a leftover of 4.8e-06.
