641400 divided by 82 
We want to figure out the number of times 641400 can be divided by 82.

Step 1:
When dividing 6 by 82, 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.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 82

On to step 2:
If we divide 64 by 82, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 82

Going ahead to step 3:
641 divided by 82 is 7 with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 574 away from 641, we end up with 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 82

Let's proceed to step 4:
The number 82 fits into 674 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 656 from 674 and we're left with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 82

Moving on to step 5:
When dividing 180 by 82, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 782.0
Subtract 164 from 180 to get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 82

Moving on to step 6:
The number 82 fits into 160 1 times, leaving a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 7821.0
Deduct 82 from 160 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 7:
780 divided by 82 is 9 with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 7821.9
Subtract 738 from 780 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
When dividing 420 by 82, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 7821.95
Subtract 410 from 420 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
82 goes into 100 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 7821.951
The remainder is 18 after subtracting 82 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
82 goes into 180 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 7821.9512
If we take 164 away from 180, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
160 divided by 82 is 1 with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 7821.95121
If we take 82 away from 160, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 12:
82 can be fit into 780 9 times, resulting in a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 7821.951219
Deduct 738 from 780 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
82 goes into 420 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 7821.9512195
The remainder is 10 after subtracting 410 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
100 divided by 82 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 7821.95121951
If we take 82 away from 100, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 7821.95121951 with a remaining 1.8e-08.
