We're dividing 66618387 by 397 
We're looking to find how many times 397 goes into 66618387.

Moving on to step 1:
When dividing 6 by 397, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 397

Moving on to step 2:
If we divide 66 by 397, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 397

On to step 3:
666 divided by 397 is 1 with a remainder of 269.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 397 from 666, we get 269.
Append the next digit (1) from the dividend to 269 and continue with: 2691 / 397

Going ahead to step 4:
397 goes into 2691 6 times with a remainder of 309.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2382 from 2691 leaves us with 309.
Take the next digit (8) from the dividend and append it to 309, then repeat: 3098 / 397

Step 5:
397 can be fit into 3098 7 times, resulting in a remainder of 319.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
Deduct 2779 from 3098 and we're left with 319.
Grab the next digit (3) from the dividend, add it to 319, then carry on: 3193 / 397

Going ahead to step 6:
If we divide 3193 by 397, we get 8 and a remainder of 17.
The next digit of our result is 8. 
Result so far: 1678.0
Subtracting 3176 from 3193 leaves us with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 397

Advancing to step 7:
The number 397 fits into 178 0 times, leaving a remainder of 178.
The next digit of our result is 0. 
Result so far: 16780.0
Subtract 0 from 178 to get 178.
Append the next digit (7) from the dividend to 178 and continue with: 1787 / 397

On to step 8:
397 goes into 1787 4 times with a remainder of 199.
Record the quotient 4 as the next digit in the result. 
Result so far: 167804.0
The remainder is 199 after subtracting 1588 from 1787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 9:
If we divide 1990 by 397, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 167804.5
The remainder is 5 after subtracting 1985 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
397 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 167804.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
If we divide 500 by 397, we get 1 and a remainder of 103.
Record the quotient 1 as the next digit in the result. 
Result so far: 167804.501
Subtract 397 from 500 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 12:
When dividing 1030 by 397, we get 2 with a remainder of 236.
Write down 2 as next digit of the result. 
Result so far: 167804.5012
Subtracting 794 from 1030 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 13:
When dividing 2360 by 397, we get 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 167804.50125
Subtracting 1985 from 2360 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 14:
The number 397 fits into 3750 9 times, leaving a remainder of 177.
The next digit of our result is 9. 
Result so far: 167804.501259
Subtracting 3573 from 3750 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 15:
If we divide 1770 by 397, we get 4 and a remainder of 182.
The next digit of our result is 4. 
Result so far: 167804.5012594
Deduct 1588 from 1770 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 16:
When dividing 1820 by 397, we get 4 with a remainder of 232.
The next digit of our result is 4. 
Result so far: 167804.50125944
Subtracting 1588 from 1820 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The final outcome is 167804.50125944, with a leftover of 2.32e-07.
