66507464 divided by 120 
Our goal is to divide 66507464 by 120.

Moving on to step 1:
120 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 120

Let's proceed to step 2:
66 divided by 120 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 120

Going ahead to step 3:
If we divide 665 by 120, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 600 from 665 leaves us with 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 120

Let's proceed to step 4:
650 divided by 120 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Deduct 600 from 650 and we're left with 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 120

Advancing to step 5:
The number 120 fits into 507 4 times, leaving a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 554.0
Deduct 480 from 507 and we're left with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 120

On to step 6:
When dividing 274 by 120, we get 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 5542.0
Subtracting 240 from 274 leaves us with 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 120

On to step 7:
120 goes into 346 2 times with a remainder of 106.
Use 2 as the next digit of our solution. 
Result so far: 55422.0
If we take 240 away from 346, we end up with 106.
Fetch the next digit (4) from the dividend, attach it to 106 and continue: 1064 / 120

Step 8:
When dividing 1064 by 120, we get 8 with a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 554228.0
The remainder is 104 after subtracting 960 from 1064.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 9:
1040 divided by 120 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 554228.8
Subtract 960 from 1040 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
If we divide 800 by 120, we get 6 and a remainder of 80.
The next digit of our result is 6. 
Result so far: 554228.86
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
The number 120 fits into 800 6 times, leaving a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 554228.866
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 554228.866, with a leftover of 0.008.
