We're dividing 66270217 by 597 
Our goal is to divide 66270217 by 597.

Let's proceed to step 1:
If we divide 6 by 597, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 597

Moving on to step 2:
When dividing 66 by 597, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 597

Moving on to step 3:
597 can be fit into 662 1 times, resulting in a remainder of 65.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 65 after subtracting 597 from 662.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 597

On to step 4:
657 divided by 597 is 1 with a remainder of 60.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 597 from 657 to get 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 597

Moving on to step 5:
597 can be fit into 600 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 111.0
The remainder is 3 after subtracting 597 from 600.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 597

Advancing to step 6:
The number 597 fits into 32 0 times, leaving a remainder of 32.
The next digit of our result is 0. 
Result so far: 1110.0
If we take 0 away from 32, we end up with 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 597

Advancing to step 7:
597 goes into 321 0 times with a remainder of 321.
Write down 0 as next digit of the result. 
Result so far: 11100.0
Subtract 0 from 321 to get 321.
Grab the next digit (7) from the dividend, add it to 321, then carry on: 3217 / 597

Going ahead to step 8:
When dividing 3217 by 597, we get 5 with a remainder of 232.
The next digit of our result is 5. 
Result so far: 111005.0
If we subtract 2985 from 3217, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 9:
2320 divided by 597 is 3 with a remainder of 529.
Write down 3 as next digit of the result. 
Result so far: 111005.3
If we subtract 1791 from 2320, we get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Step 10:
If we divide 5290 by 597, we get 8 and a remainder of 514.
The number 8 becomes the next digit in our result. 
Result so far: 111005.38
Subtracting 4776 from 5290 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 11:
If we divide 5140 by 597, we get 8 and a remainder of 364.
Record the quotient 8 as the next digit in the result. 
Result so far: 111005.388
The remainder is 364 after subtracting 4776 from 5140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final result is 111005.388 with a remainder of 0.0364.
