39418830 ÷ 166 
We're looking to find how many times 166 goes into 39418830.

Going ahead to step 1:
166 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 166

Advancing to step 2:
When dividing 39 by 166, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 166

Step 3:
166 goes into 394 2 times with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 62 after subtracting 332 from 394.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 166

Step 4:
166 goes into 621 3 times with a remainder of 123.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 498 from 621 leaves us with 123.
Take the next digit (8) from the dividend and append it to 123, then repeat: 1238 / 166

Advancing to step 5:
When dividing 1238 by 166, we get 7 with a remainder of 76.
The next digit of our result is 7. 
Result so far: 237.0
Deduct 1162 from 1238 and we're left with 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 166

Advancing to step 6:
166 goes into 768 4 times with a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 2374.0
Subtract 664 from 768 to get 104.
Include the next digit (3) from the dividend after 104, then repeat: 1043 / 166

Advancing to step 7:
The number 166 fits into 1043 6 times, leaving a remainder of 47.
The next digit of our result is 6. 
Result so far: 23746.0
Subtracting 996 from 1043 leaves us with 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 166

Let's proceed to step 8:
166 goes into 470 2 times with a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 237462.0
Subtracting 332 from 470 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 9:
166 goes into 1380 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 237462.8
If we subtract 1328 from 1380, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
If we divide 520 by 166, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 237462.83
Deduct 498 from 520 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
If we divide 220 by 166, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 237462.831
If we take 166 away from 220, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
The number 166 fits into 540 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 237462.8313
Deduct 498 from 540 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
If we divide 420 by 166, we get 2 and a remainder of 88.
The next digit of our result is 2. 
Result so far: 237462.83132
Subtract 332 from 420 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 14:
The number 166 fits into 880 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 237462.831325
If we take 830 away from 880, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 15:
166 can be fit into 500 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 237462.8313253
If we take 498 away from 500, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 16:
166 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 237462.8313253
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 237462.8313253 and a remainder of 2e-08.
