52635987 ÷ 66 
We want to divide 52635987 by 66.

Advancing to step 1:
5 divided by 66 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 66

Step 2:
When dividing 52 by 66, we get 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Include the next digit (6) from the dividend after 52, then repeat: 526 / 66

Let's proceed to step 3:
66 goes into 526 7 times with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 462 from 526, we get 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 66

Advancing to step 4:
When dividing 643 by 66, we get 9 with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 79.0
Deduct 594 from 643 and we're left with 49.
Append the next digit (5) from the dividend to 49 and continue with: 495 / 66

Going ahead to step 5:
If we divide 495 by 66, we get 7 and a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 797.0
If we take 462 away from 495, we end up with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 66

Moving on to step 6:
If we divide 339 by 66, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 7975.0
The remainder is 9 after subtracting 330 from 339.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 66

Going ahead to step 7:
If we divide 98 by 66, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 79751.0
Subtract 66 from 98 to get 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 66

Going ahead to step 8:
If we divide 327 by 66, we get 4 and a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 797514.0
If we subtract 264 from 327, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
The number 66 fits into 630 9 times, leaving a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 797514.9
If we subtract 594 from 630, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
If we divide 360 by 66, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 797514.95
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
300 divided by 66 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 797514.954
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
If we divide 360 by 66, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 797514.9545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 797514.95454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
66 goes into 360 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 797514.954545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 15:
When dividing 300 by 66, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 797514.9545454
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 16:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 797514.95454545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 797514.95454545 and a remainder of 3e-08.
