We're dividing 453458 by 69 
We want to figure out the number of times 453458 can be divided by 69.

Advancing to step 1:
4 divided by 69 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 69

Advancing to step 2:
The number 69 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 69

Going ahead to step 3:
69 goes into 453 6 times with a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 414 away from 453, we end up with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 69

Advancing to step 4:
394 divided by 69 is 5 with a remainder of 49.
The next digit of our result is 5. 
Result so far: 65.0
Subtracting 345 from 394 leaves us with 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 69

Moving on to step 5:
When dividing 495 by 69, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 657.0
If we take 483 away from 495, we end up with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 69

On to step 6:
69 goes into 128 1 times with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 6571.0
If we subtract 69 from 128, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 7:
69 goes into 590 8 times with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 6571.8
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:
69 can be fit into 380 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 6571.85
If we take 345 away from 380, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
If we divide 350 by 69, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6571.855
If we subtract 345 from 350, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 6571.855 and a remainder of 0.0005.
