We look at the division of 66490099 by 4 
We want to divide 66490099 by 4.

Advancing to step 1:
6 divided by 4 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 4 from 6 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 4

Step 2:
The number 4 fits into 26 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 4

Step 3:
If we divide 24 by 4, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 166.0
Deduct 24 from 24 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 4

Going ahead to step 4:
The number 4 fits into 9 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 1662.0
If we subtract 8 from 9, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 4

Advancing to step 5:
4 goes into 10 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 16622.0
Subtracting 8 from 10 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 4

Moving on to step 6:
4 goes into 20 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 166225.0
If we subtract 20 from 20, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 4

Step 7:
4 can be fit into 9 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 1662252.0
The remainder is 1 after subtracting 8 from 9.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 4

Step 8:
19 divided by 4 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 16622524.0
Subtract 16 from 19 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 16622524.7
If we take 28 away from 30, 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.

Advancing to step 10:
When dividing 20 by 4, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 16622524.75
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16622524.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16622524.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 16622524.75, with a leftover of 0.0.
