66607509 ÷ 652 
We want to figure out the number of times 66607509 can be divided by 652.

Advancing to step 1:
When dividing 6 by 652, 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 subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 652

Moving on to step 2:
The number 652 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 652

Moving on to step 3:
666 divided by 652 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 652 from 666 to get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 652

Let's proceed to step 4:
The number 652 fits into 140 0 times, leaving a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 140, we end up with 140.
Include the next digit (7) from the dividend after 140, then repeat: 1407 / 652

On to step 5:
The number 652 fits into 1407 2 times, leaving a remainder of 103.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtract 1304 from 1407 to get 103.
Take the next digit (5) from the dividend and append it to 103, then repeat: 1035 / 652

On to step 6:
The number 652 fits into 1035 1 times, leaving a remainder of 383.
The next digit of our result is 1. 
Result so far: 1021.0
Deduct 652 from 1035 and we're left with 383.
Grab the next digit (0) from the dividend, add it to 383, then carry on: 3830 / 652

Let's proceed to step 7:
3830 divided by 652 is 5 with a remainder of 570.
Write down 5 as next digit of the result. 
Result so far: 10215.0
Subtracting 3260 from 3830 leaves us with 570.
Fetch the next digit (9) from the dividend, attach it to 570 and continue: 5709 / 652

Let's proceed to step 8:
5709 divided by 652 is 8 with a remainder of 493.
Put 8 as the next digit of the answer. 
Result so far: 102158.0
Subtract 5216 from 5709 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Advancing to step 9:
652 goes into 4930 7 times with a remainder of 366.
The number 7 becomes the next digit in our result. 
Result so far: 102158.7
If we take 4564 away from 4930, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 10:
652 can be fit into 3660 5 times, resulting in a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 102158.75
The remainder is 400 after subtracting 3260 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
If we divide 4000 by 652, we get 6 and a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 102158.756
If we take 3912 away from 4000, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
652 can be fit into 880 1 times, resulting in a remainder of 228.
Put 1 as the next digit of the answer. 
Result so far: 102158.7561
Subtracting 652 from 880 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 13:
The number 652 fits into 2280 3 times, leaving a remainder of 324.
The next digit of our result is 3. 
Result so far: 102158.75613
Subtract 1956 from 2280 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 14:
652 can be fit into 3240 4 times, resulting in a remainder of 632.
Put 4 as the next digit of the answer. 
Result so far: 102158.756134
Deduct 2608 from 3240 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 15:
652 can be fit into 6320 9 times, resulting in a remainder of 452.
Record the quotient 9 as the next digit in the result. 
Result so far: 102158.7561349
If we take 5868 away from 6320, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 16:
652 goes into 4520 6 times with a remainder of 608.
Record the quotient 6 as the next digit in the result. 
Result so far: 102158.75613496
Subtract 3912 from 4520 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

In conclusion, the division gives 102158.75613496 with a balance of 6.08e-07.
