66329900 divided by 166 
We want to figure out the number of times 66329900 can be divided by 166.

Step 1:
The number 166 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 166

Moving on to step 2:
The number 166 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 166

Advancing to step 3:
166 goes into 663 3 times with a remainder of 165.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 498 away from 663, we end up with 165.
Bring next digit (2) of the dividend behind the 165 and repeat the process: 1652 / 166

Moving on to step 4:
If we divide 1652 by 166, we get 9 and a remainder of 158.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 158 after subtracting 1494 from 1652.
Fetch the next digit (9) from the dividend, attach it to 158 and continue: 1589 / 166

Moving on to step 5:
1589 divided by 166 is 9 with a remainder of 95.
Record the quotient 9 as the next digit in the result. 
Result so far: 399.0
Subtracting 1494 from 1589 leaves us with 95.
Take the next digit (9) from the dividend and append it to 95, then repeat: 959 / 166

Going ahead to step 6:
When dividing 959 by 166, we get 5 with a remainder of 129.
Record the quotient 5 as the next digit in the result. 
Result so far: 3995.0
The remainder is 129 after subtracting 830 from 959.
Append the next digit (0) from the dividend to 129 and continue with: 1290 / 166

Moving on to step 7:
1290 divided by 166 is 7 with a remainder of 128.
Write down 7 as next digit of the result. 
Result so far: 39957.0
If we subtract 1162 from 1290, we get 128.
Grab the next digit (0) from the dividend, add it to 128, then carry on: 1280 / 166

Moving on to step 8:
If we divide 1280 by 166, we get 7 and a remainder of 118.
The next digit of our result is 7. 
Result so far: 399577.0
Subtract 1162 from 1280 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 9:
1180 divided by 166 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 399577.7
The remainder is 18 after subtracting 1162 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
The number 166 fits into 180 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 399577.71
Subtracting 166 from 180 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
166 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 399577.71
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
If we divide 1400 by 166, we get 8 and a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 399577.7108
Subtracting 1328 from 1400 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
The number 166 fits into 720 4 times, leaving a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 399577.71084
If we subtract 664 from 720, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
560 divided by 166 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 399577.710843
If we take 498 away from 560, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 15:
620 divided by 166 is 3 with a remainder of 122.
Use 3 as the next digit of our solution. 
Result so far: 399577.7108433
Deduct 498 from 620 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

After the division, we end up with 399577.7108433 and a remainder of 1.22e-06.
