420511 ÷ 68 
We're looking to find how many times 68 goes into 420511.

Moving on to step 1:
68 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 68

Going ahead to step 2:
When dividing 42 by 68, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 68

Moving on to step 3:
68 goes into 420 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 12 after subtracting 408 from 420.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 68

Advancing to step 4:
68 goes into 125 1 times with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 61.0
The remainder is 57 after subtracting 68 from 125.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 68

Step 5:
If we divide 571 by 68, we get 8 and a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 618.0
The remainder is 27 after subtracting 544 from 571.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 68

Going ahead to step 6:
When dividing 271 by 68, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 6183.0
Deduct 204 from 271 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
68 can be fit into 670 9 times, resulting in a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 6183.9
The remainder is 58 after subtracting 612 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
If we divide 580 by 68, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 6183.98
If we take 544 away from 580, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
The number 68 fits into 360 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 6183.985
Deduct 340 from 360 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
68 goes into 200 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 6183.9852
If we take 136 away from 200, 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.

Moving on to step 11:
68 can be fit into 640 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 6183.98529
Subtract 612 from 640 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
280 divided by 68 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 6183.985294
If we take 272 away from 280, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
68 can be fit into 80 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 6183.9852941
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
68 goes into 120 1 times with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 6183.98529411
If we subtract 68 from 120, we 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.

The final result is 6183.98529411 with a remainder of 5.2e-08.
