We're dividing 515351 by 69 
We want to figure out the number of times 515351 can be divided by 69.

Going ahead to step 1:
5 divided by 69 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 69

Let's proceed to step 2:
51 divided by 69 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 69

On to step 3:
The number 69 fits into 515 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 483 from 515 leaves us with 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 69

On to step 4:
69 can be fit into 323 4 times, resulting in a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 47 after subtracting 276 from 323.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 69

Advancing to step 5:
69 goes into 475 6 times with a remainder of 61.
Use 6 as the next digit of our solution. 
Result so far: 746.0
If we take 414 away from 475, we end up with 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 69

Advancing to step 6:
69 goes into 611 8 times with a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 7468.0
Subtracting 552 from 611 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
When dividing 590 by 69, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 7468.8
If we take 552 away from 590, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
The number 69 fits into 380 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 7468.85
The remainder is 35 after subtracting 345 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
The number 69 fits into 350 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 7468.855
Subtracting 345 from 350 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 7468.855, with a leftover of 0.0005.
