We're dividing 18377720 by 166 
Let's see how many times 166 fits into 18377720.

Going ahead to step 1:
The number 166 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 166

On to step 2:
166 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 166

Let's proceed to step 3:
When dividing 183 by 166, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 166 away from 183, we end up with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 166

On to step 4:
When dividing 177 by 166, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 166 from 177 and we're left with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 166

Step 5:
166 can be fit into 117 0 times, resulting in a remainder of 117.
The next digit of our result is 0. 
Result so far: 110.0
The remainder is 117 after subtracting 0 from 117.
Take the next digit (7) from the dividend and append it to 117, then repeat: 1177 / 166

Advancing to step 6:
1177 divided by 166 is 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 1107.0
The remainder is 15 after subtracting 1162 from 1177.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 166

Going ahead to step 7:
152 divided by 166 is 0 with a remainder of 152.
Put 0 as the next digit of the answer. 
Result so far: 11070.0
Subtract 0 from 152 to get 152.
Grab the next digit (0) from the dividend, add it to 152, then carry on: 1520 / 166

Going ahead to step 8:
166 goes into 1520 9 times with a remainder of 26.
The next digit of our result is 9. 
Result so far: 110709.0
Subtracting 1494 from 1520 leaves us 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.

Let's proceed to step 9:
166 can be fit into 260 1 times, resulting in a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 110709.1
If we take 166 away from 260, we end up 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 10:
166 goes into 940 5 times with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 110709.15
If we subtract 830 from 940, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 11:
The number 166 fits into 1100 6 times, leaving a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 110709.156
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.

Moving on to step 12:
166 goes into 1040 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 110709.1566
If we take 996 away from 1040, we end up with 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 outcome is 110709.1566, with a leftover of 0.00044.
