We're dividing 66589418 by 607 
We're looking to find how many times 607 goes into 66589418.

Step 1:
When dividing 6 by 607, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 607

Moving on to step 2:
66 divided by 607 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 607

Step 3:
665 divided by 607 is 1 with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 58 after subtracting 607 from 665.
Append the next digit (8) from the dividend to 58 and continue with: 588 / 607

Advancing to step 4:
If we divide 588 by 607, we get 0 and a remainder of 588.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 588, we get 588.
Fetch the next digit (9) from the dividend, attach it to 588 and continue: 5889 / 607

Let's proceed to step 5:
5889 divided by 607 is 9 with a remainder of 426.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Deduct 5463 from 5889 and we're left with 426.
Include the next digit (4) from the dividend after 426, then repeat: 4264 / 607

On to step 6:
If we divide 4264 by 607, we get 7 and a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 1097.0
Deduct 4249 from 4264 and we're left with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 607

Let's proceed to step 7:
151 divided by 607 is 0 with a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 10970.0
Subtract 0 from 151 to get 151.
Fetch the next digit (8) from the dividend, attach it to 151 and continue: 1518 / 607

On to step 8:
If we divide 1518 by 607, we get 2 and a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 109702.0
If we take 1214 away from 1518, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 9:
The number 607 fits into 3040 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 109702.5
Subtracting 3035 from 3040 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
If we divide 50 by 607, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 109702.5
If we subtract 0 from 50, we 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.

Going ahead to step 11:
If we divide 500 by 607, we get 0 and a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 109702.5
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 109702.5 with a remaining 0.05.
