We're dividing 39099209 by 166 
We want to divide 39099209 by 166.

Going ahead to step 1:
166 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 166

Step 2:
The number 166 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 166

Going ahead to step 3:
390 divided by 166 is 2 with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 332 from 390 to get 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 166

Step 4:
When dividing 589 by 166, we get 3 with a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 498 away from 589, we end up with 91.
Bring next digit (9) of the dividend behind the 91 and repeat the process: 919 / 166

Moving on to step 5:
919 divided by 166 is 5 with a remainder of 89.
The next digit of our result is 5. 
Result so far: 235.0
The remainder is 89 after subtracting 830 from 919.
Fetch the next digit (2) from the dividend, attach it to 89 and continue: 892 / 166

Advancing to step 6:
If we divide 892 by 166, we get 5 and a remainder of 62.
Put 5 as the next digit of the answer. 
Result so far: 2355.0
Subtract 830 from 892 to get 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 166

Moving on to step 7:
620 divided by 166 is 3 with a remainder of 122.
The number 3 becomes the next digit in our result. 
Result so far: 23553.0
Subtracting 498 from 620 leaves us with 122.
Grab the next digit (9) from the dividend, add it to 122, then carry on: 1229 / 166

Moving on to step 8:
1229 divided by 166 is 7 with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 235537.0
Subtracting 1162 from 1229 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 9:
166 goes into 670 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 235537.4
Subtract 664 from 670 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
166 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 235537.4
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
If we divide 600 by 166, we get 3 and a remainder of 102.
The number 3 becomes the next digit in our result. 
Result so far: 235537.403
Subtracting 498 from 600 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 12:
The number 166 fits into 1020 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 235537.4036
If we subtract 996 from 1020, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
If we divide 240 by 166, we get 1 and a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 235537.40361
Subtracting 166 from 240 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
740 divided by 166 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 235537.403614
If we subtract 664 from 740, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 15:
166 goes into 760 4 times with a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 235537.4036144
If we take 664 away from 760, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Our division results in 235537.4036144 with a remaining 9.6e-07.
