68976716 ÷ 421 
Our goal is to divide 68976716 by 421.

Step 1:
When dividing 6 by 421, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 421

Going ahead to step 2:
The number 421 fits into 68 0 times, leaving a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 421

Going ahead to step 3:
421 goes into 689 1 times with a remainder of 268.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 421 from 689 to get 268.
Include the next digit (7) from the dividend after 268, then repeat: 2687 / 421

Moving on to step 4:
421 goes into 2687 6 times with a remainder of 161.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2526 from 2687 leaves us with 161.
Grab the next digit (6) from the dividend, add it to 161, then carry on: 1616 / 421

Going ahead to step 5:
421 goes into 1616 3 times with a remainder of 353.
The next digit of our result is 3. 
Result so far: 163.0
Deduct 1263 from 1616 and we're left with 353.
Bring next digit (7) of the dividend behind the 353 and repeat the process: 3537 / 421

Step 6:
421 goes into 3537 8 times with a remainder of 169.
Record the quotient 8 as the next digit in the result. 
Result so far: 1638.0
If we take 3368 away from 3537, we end up with 169.
Take the next digit (1) from the dividend and append it to 169, then repeat: 1691 / 421

Let's proceed to step 7:
1691 divided by 421 is 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 16384.0
Subtracting 1684 from 1691 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 421

Advancing to step 8:
421 can be fit into 76 0 times, resulting in a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 163840.0
If we subtract 0 from 76, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
When dividing 760 by 421, we get 1 with a remainder of 339.
Record the quotient 1 as the next digit in the result. 
Result so far: 163840.1
The remainder is 339 after subtracting 421 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 10:
421 can be fit into 3390 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 163840.18
Subtract 3368 from 3390 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
421 goes into 220 0 times with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 163840.18
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 12:
When dividing 2200 by 421, we get 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 163840.1805
If we subtract 2105 from 2200, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 13:
421 can be fit into 950 2 times, resulting in a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 163840.18052
If we take 842 away from 950, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 14:
1080 divided by 421 is 2 with a remainder of 238.
The next digit of our result is 2. 
Result so far: 163840.180522
Subtracting 842 from 1080 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final result is 163840.180522 with a remainder of 2.38e-05.
