67691621 ÷ 830 
Our goal is to divide 67691621 by 830.

Step 1:
6 divided by 830 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 830

On to step 2:
830 can be fit into 67 0 times, resulting in a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 830

Step 3:
If we divide 676 by 830, we get 0 and a remainder of 676.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 676 after subtracting 0 from 676.
Include the next digit (9) from the dividend after 676, then repeat: 6769 / 830

Going ahead to step 4:
830 goes into 6769 8 times with a remainder of 129.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 6640 from 6769 to get 129.
Include the next digit (1) from the dividend after 129, then repeat: 1291 / 830

Moving on to step 5:
830 can be fit into 1291 1 times, resulting in a remainder of 461.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we subtract 830 from 1291, we get 461.
Fetch the next digit (6) from the dividend, attach it to 461 and continue: 4616 / 830

Going ahead to step 6:
830 goes into 4616 5 times with a remainder of 466.
Write down 5 as next digit of the result. 
Result so far: 815.0
If we subtract 4150 from 4616, we get 466.
Take the next digit (2) from the dividend and append it to 466, then repeat: 4662 / 830

Going ahead to step 7:
830 goes into 4662 5 times with a remainder of 512.
Use 5 as the next digit of our solution. 
Result so far: 8155.0
If we subtract 4150 from 4662, we get 512.
Append the next digit (1) from the dividend to 512 and continue with: 5121 / 830

Step 8:
5121 divided by 830 is 6 with a remainder of 141.
Record the quotient 6 as the next digit in the result. 
Result so far: 81556.0
If we subtract 4980 from 5121, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 9:
1410 divided by 830 is 1 with a remainder of 580.
Use 1 as the next digit of our solution. 
Result so far: 81556.1
If we subtract 830 from 1410, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 10:
The number 830 fits into 5800 6 times, leaving a remainder of 820.
Record the quotient 6 as the next digit in the result. 
Result so far: 81556.16
The remainder is 820 after subtracting 4980 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 11:
If we divide 8200 by 830, we get 9 and a remainder of 730.
Use 9 as the next digit of our solution. 
Result so far: 81556.169
If we take 7470 away from 8200, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Advancing to step 12:
If we divide 7300 by 830, we get 8 and a remainder of 660.
Record the quotient 8 as the next digit in the result. 
Result so far: 81556.1698
Subtract 6640 from 7300 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 13:
830 goes into 6600 7 times with a remainder of 790.
Record the quotient 7 as the next digit in the result. 
Result so far: 81556.16987
Subtract 5810 from 6600 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 14:
When dividing 7900 by 830, we get 9 with a remainder of 430.
Use 9 as the next digit of our solution. 
Result so far: 81556.169879
The remainder is 430 after subtracting 7470 from 7900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 15:
830 goes into 4300 5 times with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 81556.1698795
If we subtract 4150 from 4300, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 16:
If we divide 1500 by 830, we get 1 and a remainder of 670.
The number 1 becomes the next digit in our result. 
Result so far: 81556.16987951
Deduct 830 from 1500 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

After the division, we end up with 81556.16987951 and a remainder of 6.7e-07.
