Let's divide 19795059 by 166
We want to divide 19795059 by 166.

Moving on to step 1:
The number 166 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 166

Let's proceed to step 2:
The number 166 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 166

On to step 3:
166 goes into 197 1 times with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 166 from 197, we get 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 166

Let's proceed to step 4:
166 can be fit into 319 1 times, resulting in a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 166 away from 319, we end up with 153.
Include the next digit (5) from the dividend after 153, then repeat: 1535 / 166

Step 5:
166 goes into 1535 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Subtract 1494 from 1535 to get 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 166

Going ahead to step 6:
166 goes into 410 2 times with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 1192.0
Subtracting 332 from 410 leaves us with 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 166

Step 7:
The number 166 fits into 785 4 times, leaving a remainder of 121.
Record the quotient 4 as the next digit in the result. 
Result so far: 11924.0
If we take 664 away from 785, we end up with 121.
Grab the next digit (9) from the dividend, add it to 121, then carry on: 1219 / 166

On to step 8:
The number 166 fits into 1219 7 times, leaving a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 119247.0
Deduct 1162 from 1219 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
When dividing 570 by 166, we get 3 with a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 119247.3
If we subtract 498 from 570, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
When dividing 720 by 166, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 119247.34
Subtracting 664 from 720 leaves us 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.

Let's proceed to step 11:
166 goes into 560 3 times with a remainder of 62.
The next digit of our result is 3. 
Result so far: 119247.343
If we subtract 498 from 560, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
The number 166 fits into 620 3 times, leaving a remainder of 122.
The number 3 becomes the next digit in our result. 
Result so far: 119247.3433
If we subtract 498 from 620, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final result is 119247.3433 with a remainder of 0.00122.
