We're dividing 66758390 by 597 
We're looking to find how many times 597 goes into 66758390.

Step 1:
597 can be fit into 6 0 times, resulting in 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.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 597

Advancing to step 2:
66 divided by 597 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 597

Advancing to step 3:
597 can be fit into 667 1 times, resulting in a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 597 from 667, we get 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 597

Going ahead to step 4:
705 divided by 597 is 1 with a remainder of 108.
The next digit of our result is 1. 
Result so far: 11.0
If we take 597 away from 705, we end up with 108.
Bring next digit (8) of the dividend behind the 108 and repeat the process: 1088 / 597

Moving on to step 5:
The number 597 fits into 1088 1 times, leaving a remainder of 491.
Write down 1 as next digit of the result. 
Result so far: 111.0
Subtract 597 from 1088 to get 491.
Bring next digit (3) of the dividend behind the 491 and repeat the process: 4913 / 597

Let's proceed to step 6:
4913 divided by 597 is 8 with a remainder of 137.
Use 8 as the next digit of our solution. 
Result so far: 1118.0
If we subtract 4776 from 4913, we get 137.
Include the next digit (9) from the dividend after 137, then repeat: 1379 / 597

Advancing to step 7:
When dividing 1379 by 597, we get 2 with a remainder of 185.
Record the quotient 2 as the next digit in the result. 
Result so far: 11182.0
Subtract 1194 from 1379 to get 185.
Bring next digit (0) of the dividend behind the 185 and repeat the process: 1850 / 597

Advancing to step 8:
If we divide 1850 by 597, we get 3 and a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 111823.0
Subtract 1791 from 1850 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
597 can be fit into 590 0 times, resulting in a remainder of 590.
Put 0 as the next digit of the answer. 
Result so far: 111823.0
If we take 0 away from 590, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 10:
When dividing 5900 by 597, we get 9 with a remainder of 527.
The next digit of our result is 9. 
Result so far: 111823.09
If we take 5373 away from 5900, we end up with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Advancing to step 11:
The number 597 fits into 5270 8 times, leaving a remainder of 494.
Write down 8 as next digit of the result. 
Result so far: 111823.098
Subtracting 4776 from 5270 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 12:
When dividing 4940 by 597, we get 8 with a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 111823.0988
Subtracting 4776 from 4940 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

After the division, we end up with 111823.0988 and a remainder of 0.00164.
