66770 ÷ 48 
We're looking to find how many times 48 goes into 66770.

Let's proceed to step 1:
The number 48 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 48

Going ahead to step 2:
When dividing 66 by 48, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 48 away from 66, we end up with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 48

Advancing to step 3:
187 divided by 48 is 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 13.0
If we take 144 away from 187, we end up with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 48

Step 4:
48 can be fit into 437 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Deduct 432 from 437 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 48

On to step 5:
48 goes into 50 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1391.0
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
When dividing 20 by 48, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1391.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 48, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1391.04
Subtracting 192 from 200 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 48 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 1391.041
Deduct 48 from 80 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
When dividing 320 by 48, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1391.0416
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
48 can be fit into 320 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1391.04166
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 1391.04166 and a remainder of 3.2e-05.
