Let's divide 666520 by 69
Our goal is to divide 666520 by 69.

Going ahead to step 1:
When dividing 6 by 69, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 69

Let's proceed to step 2:
66 divided by 69 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 69

On to step 3:
69 goes into 666 9 times with a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 621 from 666 leaves us with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 69

Step 4:
455 divided by 69 is 6 with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we take 414 away from 455, we end up with 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 69

On to step 5:
69 goes into 412 5 times with a remainder of 67.
The number 5 becomes the next digit in our result. 
Result so far: 965.0
Deduct 345 from 412 and we're left with 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 69

Step 6:
69 goes into 670 9 times with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 9659.0
Deduct 621 from 670 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
When dividing 490 by 69, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 9659.7
The remainder is 7 after subtracting 483 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
70 divided by 69 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 9659.71
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
69 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 9659.71
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
69 can be fit into 100 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 9659.7101
Deduct 69 from 100 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
If we divide 310 by 69, we get 4 and a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 9659.71014
Deduct 276 from 310 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
69 can be fit into 340 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 9659.710144
If we take 276 away from 340, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 9659.710144, and the remainder is 6.4e-06.
