66042069 ÷ 60 
Our goal is to divide 66042069 by 60.

Let's proceed to step 1:
When dividing 6 by 60, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the 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 / 60

Going ahead to step 2:
60 can be fit into 66 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 60 from 66, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 60

Going ahead to step 3:
If we divide 60 by 60, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 60 from 60 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 60

Step 4:
The number 60 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 60

Moving on to step 5:
The number 60 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 1100.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 60

Advancing to step 6:
When dividing 420 by 60, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 11007.0
If we subtract 420 from 420, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 60

Moving on to step 7:
The number 60 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 110070.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 60

Let's proceed to step 8:
60 goes into 69 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1100701.0
If we take 60 away from 69, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
The number 60 fits into 90 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1100701.1
Subtracting 60 from 90 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
When dividing 300 by 60, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1100701.15
Subtracting 300 from 300 leaves us with 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 11:
The number 60 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1100701.15
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.

Step 12:
When dividing 0 by 60, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1100701.15
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1100701.15 and a remainder of 0.0.
