66420075 divided by 610 
We want to figure out the number of times 66420075 can be divided by 610.

Let's proceed to step 1:
When dividing 6 by 610, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 610

Let's proceed to step 2:
610 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 610

Let's proceed to step 3:
610 goes into 664 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 610 from 664, we get 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 610

Moving on to step 4:
542 divided by 610 is 0 with a remainder of 542.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 542 and we're left with 542.
Append the next digit (0) from the dividend to 542 and continue with: 5420 / 610

Advancing to step 5:
610 goes into 5420 8 times with a remainder of 540.
The next digit of our result is 8. 
Result so far: 108.0
The remainder is 540 after subtracting 4880 from 5420.
Bring next digit (0) of the dividend behind the 540 and repeat the process: 5400 / 610

Going ahead to step 6:
5400 divided by 610 is 8 with a remainder of 520.
Write down 8 as next digit of the result. 
Result so far: 1088.0
Subtract 4880 from 5400 to get 520.
Bring next digit (7) of the dividend behind the 520 and repeat the process: 5207 / 610

On to step 7:
610 goes into 5207 8 times with a remainder of 327.
Record the quotient 8 as the next digit in the result. 
Result so far: 10888.0
Subtract 4880 from 5207 to get 327.
Bring next digit (5) of the dividend behind the 327 and repeat the process: 3275 / 610

Let's proceed to step 8:
3275 divided by 610 is 5 with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 108885.0
If we take 3050 away from 3275, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 9:
If we divide 2250 by 610, we get 3 and a remainder of 420.
The next digit of our result is 3. 
Result so far: 108885.3
Deduct 1830 from 2250 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 10:
610 goes into 4200 6 times with a remainder of 540.
The number 6 becomes the next digit in our result. 
Result so far: 108885.36
Subtracting 3660 from 4200 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 11:
The number 610 fits into 5400 8 times, leaving a remainder of 520.
Record the quotient 8 as the next digit in the result. 
Result so far: 108885.368
The remainder is 520 after subtracting 4880 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 12:
When dividing 5200 by 610, we get 8 with a remainder of 320.
Use 8 as the next digit of our solution. 
Result so far: 108885.3688
Subtract 4880 from 5200 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 108885.3688 and a remainder of 0.0032.
