We look at the division of 396399 by 69 
We want to figure out the number of times 396399 can be divided by 69.

Going ahead to step 1:
The number 69 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 69

Going ahead to step 2:
If we divide 39 by 69, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 69

Advancing to step 3:
69 goes into 396 5 times with a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 345 from 396 to get 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 69

Moving on to step 4:
The number 69 fits into 513 7 times, leaving a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we take 483 away from 513, we end up with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 69

On to step 5:
69 can be fit into 309 4 times, resulting in a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 574.0
Subtract 276 from 309 to get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 69

Moving on to step 6:
If we divide 339 by 69, we get 4 and a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 5744.0
Deduct 276 from 339 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
630 divided by 69 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 5744.9
If we take 621 away from 630, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
69 can be fit into 90 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 5744.91
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
210 divided by 69 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 5744.913
Deduct 207 from 210 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
69 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5744.913
Deduct 0 from 30 and we're left with 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 11:
The number 69 fits into 300 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 5744.91304
The remainder is 24 after subtracting 276 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
69 goes into 240 3 times with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 5744.913043
Subtracting 207 from 240 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
69 goes into 330 4 times with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 5744.9130434
If we take 276 away from 330, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
69 goes into 540 7 times with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 5744.91304347
Subtracting 483 from 540 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 5744.91304347 with a remainder of 5.7e-08.
