Let's divide 42375972 by 66
We're looking to find how many times 66 goes into 42375972.

Moving on to step 1:
4 divided by 66 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 66

Let's proceed to step 2:
When dividing 42 by 66, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 66

Advancing to step 3:
When dividing 423 by 66, we get 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 396 from 423 to get 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 66

Going ahead to step 4:
66 can be fit into 277 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 264 from 277 to get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 66

Going ahead to step 5:
66 can be fit into 135 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 642.0
Deduct 132 from 135 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 66

Moving on to step 6:
If we divide 39 by 66, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 6420.0
If we take 0 away from 39, we end up with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 66

On to step 7:
The number 66 fits into 397 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 64206.0
Deduct 396 from 397 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 66

Let's proceed to step 8:
The number 66 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 642060.0
Deduct 0 from 12 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
If we divide 120 by 66, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 642060.1
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 10:
If we divide 540 by 66, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 642060.18
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 642060.181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
66 goes into 540 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 642060.1818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
If we divide 120 by 66, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 642060.18181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 642060.181818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 15:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 642060.1818181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 16:
66 goes into 540 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 642060.18181818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 642060.18181818 with a balance of 1.2e-08.
