We're dividing 66429066 by 178 
We want to divide 66429066 by 178.

Advancing to step 1:
6 divided by 178 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 178

Moving on to step 2:
When dividing 66 by 178, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 178

Let's proceed to step 3:
178 can be fit into 664 3 times, resulting in a remainder of 130.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 130 after subtracting 534 from 664.
Include the next digit (2) from the dividend after 130, then repeat: 1302 / 178

On to step 4:
178 can be fit into 1302 7 times, resulting in a remainder of 56.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 1246 from 1302 to get 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 178

Advancing to step 5:
The number 178 fits into 569 3 times, leaving a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 373.0
If we subtract 534 from 569, we get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 178

Going ahead to step 6:
350 divided by 178 is 1 with a remainder of 172.
The number 1 becomes the next digit in our result. 
Result so far: 3731.0
The remainder is 172 after subtracting 178 from 350.
Grab the next digit (6) from the dividend, add it to 172, then carry on: 1726 / 178

Advancing to step 7:
178 can be fit into 1726 9 times, resulting in a remainder of 124.
Use 9 as the next digit of our solution. 
Result so far: 37319.0
If we take 1602 away from 1726, we end up with 124.
Grab the next digit (6) from the dividend, add it to 124, then carry on: 1246 / 178

Going ahead to step 8:
1246 divided by 178 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 373197.0
Subtract 1246 from 1246 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.

Advancing to step 9:
0 divided by 178 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 373197.0
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.

Let's proceed to step 10:
178 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 373197.0
The remainder is 0 after subtracting 0 from 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 373197.0, with a leftover of 0.0.
