We look at the division of 45365195 by 166 
Let's see how many times 166 fits into 45365195.

Step 1:
4 divided by 166 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 166

On to step 2:
When dividing 45 by 166, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 166

On to step 3:
The number 166 fits into 453 2 times, leaving a remainder of 121.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 332 away from 453, we end up with 121.
Append the next digit (6) from the dividend to 121 and continue with: 1216 / 166

On to step 4:
166 can be fit into 1216 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 1162 from 1216 leaves us with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 166

Let's proceed to step 5:
When dividing 545 by 166, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 273.0
If we subtract 498 from 545, we get 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 166

Moving on to step 6:
When dividing 471 by 166, we get 2 with a remainder of 139.
The number 2 becomes the next digit in our result. 
Result so far: 2732.0
If we subtract 332 from 471, we get 139.
Bring next digit (9) of the dividend behind the 139 and repeat the process: 1399 / 166

Step 7:
1399 divided by 166 is 8 with a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 27328.0
If we subtract 1328 from 1399, we get 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 166

Moving on to step 8:
The number 166 fits into 715 4 times, leaving a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 273284.0
The remainder is 51 after subtracting 664 from 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
The number 166 fits into 510 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 273284.3
If we subtract 498 from 510, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
The number 166 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 273284.3
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
The number 166 fits into 1200 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 273284.307
Subtract 1162 from 1200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
166 goes into 380 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 273284.3072
If we take 332 away from 380, 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.

Advancing to step 13:
166 goes into 480 2 times with a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 273284.30722
If we take 332 away from 480, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

In conclusion, the division gives 273284.30722 with a balance of 0.000148.
