525913 divided by 66 
Our goal is to divide 525913 by 66.

On to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 66

Advancing to step 2:
66 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 66

Moving on to step 3:
When dividing 525 by 66, we get 7 with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 462 from 525 leaves us with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 66

Moving on to step 4:
66 can be fit into 639 9 times, resulting in a remainder of 45.
The next digit of our result is 9. 
Result so far: 79.0
If we subtract 594 from 639, we get 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 66

Advancing to step 5:
66 goes into 451 6 times with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 796.0
Subtracting 396 from 451 leaves us with 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 66

Moving on to step 6:
66 can be fit into 553 8 times, resulting in a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 7968.0
If we take 528 away from 553, we end up with 25.

On to step 7:
When dividing 250 by 66, we get 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 7968.3
Subtract 198 from 250 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
The number 66 fits into 520 7 times, leaving a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 7968.37
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
When dividing 580 by 66, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 7968.378
If we take 528 away from 580, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
If we divide 520 by 66, we get 7 and a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 7968.3787
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
580 divided by 66 is 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 7968.37878
If we take 528 away from 580, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
If we divide 520 by 66, we get 7 and a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 7968.378787
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 13:
580 divided by 66 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 7968.3787878
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 14:
66 goes into 520 7 times with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 7968.37878787
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.
