554194 ÷ 66 
We're looking to find how many times 66 goes into 554194.

On to step 1:
66 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 66

Moving on to step 2:
66 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 66

Step 3:
If we divide 554 by 66, we get 8 and a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 26 after subtracting 528 from 554.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 66

Going ahead to step 4:
If we divide 261 by 66, we get 3 and a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we take 198 away from 261, we end up with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 66

Advancing to step 5:
639 divided by 66 is 9 with a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 839.0
If we take 594 away from 639, we end up with 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 66

Going ahead to step 6:
454 divided by 66 is 6 with a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 8396.0
If we take 396 away from 454, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 8396.8
Subtract 528 from 580 to 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.

Going ahead to step 8:
The number 66 fits into 520 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 8396.87
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 8396.878
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
66 goes into 520 7 times with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 8396.8787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
The number 66 fits into 580 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 8396.87878
Subtract 528 from 580 to 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 12:
66 can be fit into 520 7 times, resulting in a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 8396.878787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 8396.8787878
Subtract 528 from 580 to 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.

Moving on to step 14:
The number 66 fits into 520 7 times, leaving a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 8396.87878787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 8396.87878787, with a leftover of 5.8e-08.
