166446 ÷ 19 
We want to figure out the number of times 166446 can be divided by 19.

On to step 1:
When dividing 1 by 19, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 19

Going ahead to step 2:
The number 19 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 19

On to step 3:
19 can be fit into 166 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 14 after subtracting 152 from 166.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 19

Step 4:
The number 19 fits into 144 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Deduct 133 from 144 and we're left with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 19

Let's proceed to step 5:
114 divided by 19 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 876.0
If we take 114 away from 114, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 19

Advancing to step 6:
19 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 8760.0
The remainder is 6 after subtracting 0 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
19 goes into 60 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 8760.3
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
19 goes into 30 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 8760.31
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
19 goes into 110 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8760.315
If we subtract 95 from 110, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
19 goes into 150 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 8760.3157
If we subtract 133 from 150, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 8760.31578
Subtracting 152 from 170 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 8760.315789
If we take 171 away from 180, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
19 goes into 90 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 8760.3157894
Deduct 76 from 90 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
The number 19 fits into 140 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 8760.31578947
Subtracting 133 from 140 leaves us 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.

In conclusion, the division gives 8760.31578947 with a balance of 7e-09.
